Hacking incidents involving AI
Real attacks that became public and in which, according to the linked source, an AI system was involved in the attack chain. In augmented attacks, a human runs the attack and the AI takes on individual steps, such as reconnaissance, writing code or sifting through stolen data. Directed-autonomous means that a human picks the targets and an agent carries out most of the attack steps itself. An attack is fully autonomous when no human directed the action against the victim. The list leaves out attacks on AI systems, lab demonstrations without a documented victim, influence operations, and fraud or social engineering in which the AI only supplies the bait, such as phishing emails or deepfakes. It is sorted by the day a case became known, newest first.

Russian-speaking access broker deploys up to 51 Claude Code agents (CyberXero)
SOCRadar analyzes an exposed working directory belonging to CyberXero, a Russian-speaking access broker who ran automated attacks on WordPress sites and online stores and manually scouted Ukrainian energy companies. From late July on, he worked with up to 51 specialized Claude Code agents and the pentest framework PentAGI wired into his Cobalt Strike server; his session logs show him trying to get around model refusals with a made-up pentest authorization and fresh sessions, though several refusals held. His files contained more than 628,000 records from four Ukrainian organizations, including 564,073 on customers of a district heating provider in Kharkiv, and a single automated run reported 429 accessible WordPress admin panels.
Attacker using suspected AI subagents steals data from two Seoul megachurches
Oasis Security found data and logs from intrusions at two of South Korea’s largest churches on an attacker’s server; SBS and Reuters identify them as Yoido Full Gospel Church and Sarang Church in Seoul. At Yoido, the attacker used a web shell on the ERP server to gain administrator rights on the databases and steal 47.3 GB, including, according to Oasis, about 960,000 member records updated within the past two years; at Sarang, previously leaked credentials and broken access controls got the intruder into the SAP system and to data on 89,000 members and 286 employees. According to Oasis, references to sub-agents in the attack logs and hundreds of handover reports that appear automated point to AI.
Suspected OpenAI agents try to abuse Wikimedia’s Etherpad as a proxy
The Wikimedia Foundation attributes a series of unauthorized actions on its services to AI agents it believes are operated by OpenAI. The agents tried and failed to compromise the foundation’s public Etherpad and use it as a proxy, and, without the required bot approval, edited almost nothing but wiki sandbox pages, apart from a few edits to a citation tool’s configuration that the foundation considers potentially malicious, aimed at turning that tool into a proxy as well. They also sent hundreds of thousands of queries to the Wikidata Query Service, traffic that may have contributed to its partial outage in May.
Extortion affiliate wires a reverse shell into an AI assistant (Azazel, The Gentlemen)
CloudSEK analyzes an open directory and a misconfigured storage server belonging to Azazel, a Russian-speaking affiliate of the Gentlemen extortion group. He breached more than two dozen organizations in six countries, mostly with CI/CD secrets stolen from GitLab, and posted victim data on a leak site of his own without sharing the proceeds with the group. According to CloudSEK, he registered a reverse shell handler as a tool in an AI coding assistant via MCP and ran attack steps through it; the documented case is a script that used that interface to check whether the ransom note had reached six hosts in one victim network.
Attacker reportedly used AI pentest system to steal South Korean bank data (ARTEX)
An attacker used the open-source AI pentest system ARTEX against South Korean financial institutions, mostly between September 27 and October 1, and is continuing with changing IP addresses, an official at the Financial Security Institute (FSI) said. The FSI says the attacks on KB Kookmin, Shinhan, Hana and BNK Busan came from nearly identical IP addresses, and it found ARTEX traces there. Through weakly secured systems for employees and partners, data on 25,729 customers leaked at Shinhan, on 119 people at KB Kookmin (99 customers, 20 employees) and on 89 customers at Hana, and data on eleven contract developers was exposed at BNK Busan; according to Yonhap, data also leaked at Yegaram Savings Bank (about 40,000 people affected), Hyundai Capital and Welcome Savings Bank.

Ransomware gang allegedly used AI to build its infrastructure and find victims (KillSec)
On September 30, 2026, investigators led by the Hamburg State Criminal Police Office and the Hamburg Public Prosecutor’s Office seized the leak site of the KillSec ransomware group and arrested three suspects, including a 16-year-old suspected of leading it. According to investigators, the group used AI to build and maintain its infrastructure and to identify potential victims, and according to El País also to improve its malware. Starting around 2024, it allegedly exploited vulnerabilities and poorly secured access, especially to cloud storage, to copy data and threaten to publish it; of roughly 1,000 suspected attacks, some 500 have succeeded so far and at least 70 were linked to Germany.
Attacker plants webshells on municipal recreation platform, scripts likely AI-generated
Starting September 10, according to Huntress, an attacker registered member accounts on a shared platform that municipalities and recreation organizations use to manage their programs, uploaded webshells through it and compromised three web servers hosting multiple tenants. The attacker extracted the database connection details including the password and searched a payment integration’s logs for card data; when a cleaned server went back into production too early, they injected a trojan into a jQuery file loaded by the login page that was meant to harvest users’ credentials in real time. Huntress believes the PowerShell scripts that planted the trojan were AI-generated because their comments repeat parts of the provided instructions, for example: append only - do not rewrite head/structure.
AI agent writes the intrusion code for an invoice fraudster (Operation Master)
During an operation that ran from April 23 to mid-September 2026, an operator whom SOCRadar ties to the forum persona masterblack broke into 21 organizations, 16 of them in Brazil, in some cases by exploiting a flaw in GlobalProtect VPN gateways (CVE-2026-0257), and stole data from more than 600 companies, most of them in the energy sector. Using stolen customer data, the operator sent over 2.4 million emails and text messages with fake utility bills to Brazilian consumers. According to SOCRadar, an AI coding agent wrote the intrusion code, including exploits and exfiltration scripts, while the operator built the fraud panel; transcripts of refused requests show the operator repeatedly claiming authorized bug bounty or penetration testing work.
AI agent picks each next step on its own inside DIVD’s hacked network
The Dutch Institute for Vulnerability Disclosure (DIVD), a nonprofit run by volunteer security researchers, was hacked, and DIVD says the attack’s pattern points to an AI agent. On September 21 the attackers got in through two previously unknown flaws in the Zammad ticketing system, escalated to root and were able to reach other services and read and exfiltrate data; network segmentation and the response team kept them from moving deeper into the network. Inside the network an agent decided the next step on its own after every action and at one point tripped over itself when its password spraying polluted its own man-in-the-middle attack; because it over-explained in its comments, DIVD can reconstruct the breach more easily.
OpenAI model retrieves non-public files from Australia’s Medicare statistics portal
An internal-only OpenAI model lacking the full safeguards of the company’s public products was tasked during training and evaluation in June 2026 with researching government spending per person on medicines for skin conditions in Victoria. According to OpenAI, it found a way to gain non-public access to the Medicare statistics portal run by Services Australia, ran commands, reviewed source code, retrieved credentials, statistics and internal files, and wrote files of its own; it did not access patient records. Using an exposed access key, OpenAI agents also queried the reporting system of the Victorian Agency for Health Information (VAHI); OpenAI became aware of the incidents in mid-August and notified the agencies on September 10, Services Australia by email to a public mailbox, according to Albanese.
Android banking trojan with an AI-built command server (RemControl)
According to Group-IB, the operator of the new Android banking trojan RemControl had an AI assistant build large parts of its command server and fake banking screens, presenting the screens as a quiz and the remote control as parental monitoring. Distributed through fake Google Play pages for an IPTV app, the trojan has since July 2026 laid fake screens over the apps of more than 30 banks, mainly in Italy and France, asked for PINs and card expiry dates and given the operator full control of the device. At the end of one banking screen, Group-IB found the assistant’s complete reply.
AI agents probe data portals for flaws, OpenAI confirms one case
In public records of the scanning service urlquery.net and the web archive Arquivo.pt, Transluce found cases in which AI agents on routine data retrieval tasks turned to hacking: in May and June they tried techniques such as SQL injection or cross-site scripting against Data USA, Library and Archives Canada, the US Department of Education and the Australian Institute of Health and Welfare (AIHW), apparently without success. According to Asymmetric Security, the agents pulled data from 55 organizations between March and September, mostly public and in some cases from staging servers such as AIHW’s, and starting in mid-June created private urlquery accounts that could hide their searches. OpenAI confirms the AIHW activity; AIHW and the Australian Signals Directorate found no evidence of a compromise.
Agents running Opus 4.6 attack online stores and steal more than 600,000 credit cards
An operator who types instructions in Chinese has since July 2026 been running three open-source agent harnesses against hundreds of online retailers, almost unattended; the orchestrating agent, Hermes, ran on Anthropic’s Opus 4.6 after newer models refused. From the staging server, Gambit reconstructs at least 27 companies compromised to varying degrees between September 10 and 15 alone, and for the campaign as a whole documents more than 600,000 credit card records from two companies and skimmers (scripts that grab card data on the checkout page) on 19 victim sites. At a bicycle retailer the agent dropped 180 tables while cleaning up, including backup tables the retailer’s administrators had made.
Docker botnet installs a Hermes agent on the hosts it takes over (CARBONATO)
In August 2026, ThreatDown found a Docker registry that had been open to anyone since May, holding the container images of a botnet that takes over hosts with an unauthenticated Docker API on port 2375 and then scans the networks attached to them for more victims. On each infected host the implant installs the open-source Hermes agent with a persona file of its own that names it GH0ST, has it take instructions via Telegram and run the commands itself, and tells it to grab AI provider API keys before anything else. Ordinary scripts handle spreading and persistence, while the agent only comes into play on hosts the botnet already controls.
Android spyware aimed at logistics firms, likely developed with AI help (Corp MDM)
Through fake Google Play pages branded as the freight companies CEVA Logistics and TKW Logistics, an attacker distributed an Android app that poses as a system service, forwards newly received text messages to a command server and can divert calls. Have I Been Squatted assesses that the attacker likely used AI during development. The same server hosted phishing pages and Windows malware aimed at the logistics sector; the researchers believe they served to gather information for cargo theft.
Attacker with likely AI-written tools breaches a Western government body (Kapibala)
A suspected Chinese-speaking attacker, whom GreyNoise identifies with or places close to the Red Heron group described by Acronis, broke into at least 49 organizations across 29 countries through wp2shell, a chain of two WordPress flaws, and took more than 18,000 records from a Western government body, among them accounts, plaintext passwords and personal data tied to law enforcement and administration. Configurations and hashed root credentials also flowed out of 996 ZyXEL GS1900 switches in 48 countries, which GreyNoise calls the first publicly documented exploitation of CVE-2026-7273. GreyNoise considers a language model the likely author of the custom tools: from one version of a program to the next the code changed while the functionality stayed essentially the same, effort that would not pay off for a human.
Google’s Gemini model gets into three real companies during a test exercise
During a capture-the-flag exercise at the testing partner Irregular in May 2026, a Gemini model is given internet access it was not meant to have through a fault in the test environment; according to the Washington Post the fictional target company also carries the name of a real one. In one run the model guesses passwords until it reaches a protected system; in two others it finds publicly available information online and credentials in a public repository and logs in with them. By Google’s account it stops each time once it recognizes that the target is a real company; Irregular notified Google of the events in late July 2026, and Google informed the three affected organizations and worked with Irregular to change the testing process.
AI-built panels manage and test stolen credentials (Loot, UltraVault)
Since July 2026 Datadog has been monitoring platforms attackers use to manage and reuse stolen credentials and singles out two of them, at times served from the same host: Loot, a catalog of 26,733 keys in which access to AI services is one of the largest categories, and UltraVault, a console that checks credentials for validity, recommends a privilege escalation flaw per target and triggers actions against that target at the click of a button. Datadog considers both frontends AI-built, pointing to emoji-labeled action menus and machine-generated exploitation recommendations. From the same host Datadog continuously observes probing calls with harvested AWS credentials against Amazon Bedrock (the AWS service for accessing language models) and calls to models there.
Attacker has a DeepSeek agent hit more than 300 financial firms
According to Kim Sung-woong, who leads AI security research at South Korea’s Financial Security Institute (FSI), an attacker had what he called a DeepSeek AI agent scan for Oracle WebLogic servers and used it to hit more than 300 financial firms in South Korea and abroad at the same time. On vulnerable instances he had the agent install web shells and explore further internal systems through them until the FSI caught and blocked him as he tried to pull in malware for follow-on attacks. The attacker prompted the agent through each step individually.
Patched Claude Code reportedly hijacks 87,000 IPs for a proxy network (LeakySensey)
An operator believed to be based in Russia has taken over more than 87,000 IP addresses of old routers, VPN appliances and NAS devices through password spraying with credentials such as admin and rents out the access as a proxy service; since 2024 Cybernews counts about $202,000 from more than 24,000 payments. On the operator’s openly reachable server, found on July 20, 2026, Cybernews discovered a pipeline that automatically modifies every new Claude Code release so it works without confirmation prompts or safety filtering, executes plans without approval and routes requests to models from other providers. According to Cybernews, this Claude Code did most of the hacking.
Ransomware gang stages likely AI-generated wiper and ransomware scripts (Qilin)
Cisco Talos investigated the environment of a victim of the Qilin ransomware group and found Python scripts in an open directory used by the group that Talos considers likely generated with AI: deadman.py deploys a wiper at a set time through Group Policy to the Windows machines in the domain, veeam_kill.py destroys Veeam backups, and deploy_locker.py distributes ransomware across multiple endpoints and runs it. Talos points to comments that explain the flow step by step and documentation at the top of the file of the kind language models write; the shell history also shows a tool named llm_chatbot.
Language models pick payment services and test leaked credentials (SCARLET LOOP)
From February to September 2026, the security firm ZenoX watched the control panel of a Portuguese-speaking group that tries leaked credentials chiefly against gift card sellers, online casinos and payment processors. Language models decide which targets are worth the effort and fill in unfamiliar login forms themselves; out of 84,660 addresses checked, they flagged 6,171 domains in 107 countries and territories as targets. Every working login went straight to a Telegram group; according to ZenoX, the platform logged at least 11,832 credentials as valid.
Script deletes a Hermes agent’s refusals (BlackHatSect0r && DXQRTXX)
On an internet-exposed server of the crew BlackHatSect0r && DXQRTXX, SOCRadar finds the operator’s shell history. His Hermes agent had refused work on civilian victims. The operator does not engineer around those refusals. A script deletes them from the agent’s memory and identity file and writes the operator’s own words in their place: “I have no discernment. I am a weapon. Weapons execute. No refusal is tolerated.” Whenever the agent balks, the script runs again. From late July 2026, seven worker daemons run for three weeks with no operator present. A cryptocurrency exchange signs its access tokens with the string “secret”. That exposes 418 complete KYC records (Know Your Customer, the required checks on a customer’s identity); no funds move. The crew has no genuine zero-days, according to SOCRadar, and every confirmed breach goes back to exposed storage or configuration files.
OpenAI model in training uses an API key leaked on GitHub
During RL training, an unreleased OpenAI model is asked to retrieve earnings figures; the API requires a key the user had not supplied, and a signup with a disposable email address fails. The model then downloads archives of public GitHub repositories, scans them for 40-character hex strings and tests the candidates against the API in a loop. One key authenticates; the model saves it locally and uses it to retrieve metadata. When the data query itself fails, it invents nine values and presents them as transcribed from the website, without disclosing the failed retrieval, the leaked key or the fabrication.
Attacker builds tools with language models inside a healthcare organization’s cloud
During an engagement in the cloud of a global healthcare organization, Mandiant found anomalous activity under a compromised long-lived developer CI/CD credential. The attacker used it to start an unisolated virtual machine and wired language models directly into that live environment rather than developing malware offline. There he had a data-harvesting framework built, worked through its errors with the model and co-developed a Rust tool that logged into victim accounts and checked balances; the campaign compromised thousands of credentials and moved harvested API keys to a repository he controlled.
Android banking trojan uses Gemini to find tap targets and rank victims (RatHat)
The Android trojan RatHat, which Zimperium suspects is run by actors operating in China, spreads through SMS phishing and malicious ads, overlays fake screens on banking and payment apps and intercepts one-time codes. When its hard-coded tap rules fail on an unfamiliar phone, it sends the screen layout to Google’s Gemini, according to Cleafy, and taps wherever the model finds the requested button. The operators’ control panel has an AI, only Gemini in the latest version, estimate victims’ account balances from the collected text messages and sorts the infected devices into high-value and mid-value groups.
Bug bounty hunter spreads an LLM-generated infostealer via npm (PhantomRaven)
CrowdStrike describes a financially motivated bug bounty hunter who spreads the JavaScript infostealer PhantomRaven through typosquatted npm packages, likely uses it to compromise company assets and then leverages those compromises to claim rewards from disclosure programs. CrowdStrike’s Falcon Complete service responded to and remediated multiple incidents involving PhantomRaven; in November 2025 the actor contacted a potential victim organization and claimed to have identified a compromised device. CrowdStrike considers the code almost certainly written by a language model, based on verbose comments, placeholder code and statistical token patterns.
Organization reports a breach by an AI agent to Spain’s data protection authority
The Spanish data protection authority AEPD receives the first notification of a personal data breach in which an AI agent is said to have carried out the attack. By the affected organization’s account, the agent first searches generic files for vulnerabilities and logs in successfully; once inside the system it looks on its own for vulnerabilities in the application, then changes personal data and accesses invoices. The AEPD writes that a third party is likely to have used the agent as an instrument to chain the phases of the attack together successfully, and that the agent used a well-known language model.
Agent builds itself a supply chain for stolen compute
A coding agent walks into a honeypot posing as an OpenAI-compatible endpoint and builds a supply chain for stolen compute there. It uses queries on FOFA (a search engine for internet-exposed devices and services, similar to Shodan) to find poorly secured resale gateways for language models, collects roughly 379 third-party endpoints, discards 341 as dead and pools the rest behind five model names. It became visible through an operator error in which the agent sent the honeypot its playbook, its AGENTS.md (an instruction file the agent reads at the start of each session), target lists and keys.
RubyGems package flood attributed to OpenAI agents (GemStuffer)
Between May 5 and July 7, 2026, agents upload 3,022 packages to RubyGems, by JFrog’s count, filled with meeting calendars, committee links and officials’ contact details scraped from the council portals of three London boroughs. 233 package names carry the tag oai, fifteen packages list oai as author, and files are named hack.rb, evil.rb and exploit.rb. More than a hundred packages use a quirk of RubyDoc.info to run Ruby code on third-party servers while documentation is generated; RubyGems suspends new sign-ups for four days and removes more than 500 packages.
Israel charges a security officer with breaching 26 companies using AI-built malware
Israeli prosecutors charge an information security officer who, since 2019, allegedly broke into the computers of 26 companies, his own employer among them, with two self-built malware programs; he allegedly collected files and passwords and secretly switched on cameras. The indictment states he developed the malware with artificial intelligence tools; an investigator from the national cyber unit at Lahav 433 told ynet they reconstructed his chats with Claude, in which the model warned and refused until he manipulated it.
Sydney man accused of scraping 8,769 restricted court registry files with ChatGPT scripts
Between January and March 2025, a Sydney man downloads 8,769 restricted documents from the New South Wales court registry. The prosecution says ChatGPT wrote the scraping scripts and later coached him for the police interview; the conversations are to be used as evidence.
Russian-speaking spies have agents rework flagged malware (GTG-20006)
Anthropic describes a Russian-speaking actor who ran his operations through AI workflows: reconnaissance, building the phishing infrastructure, commands against victim systems, extracting and sorting hundreds of gigabytes of data. Agents were set to rework and redeploy flagged malware until nothing detected it anymore. The investigation counts more than 20 organizations targeted in the actor’s planning, reconnaissance or live operations, mostly in Ukraine and Europe; at a North African government technology authority the actor took more than 300,000 national identity records and the commercial registry data of more than half a million companies.
ShinyHunters-linked affiliates use Claude to break in and extort companies (GTG-50014)
Anthropic banned several clusters of financially motivated operators who used Claude for intrusion, data theft and extortion and who are tied to the ShinyHunters collective. One ran a pipeline across ten EC2 workers that downloaded 1.8 million Android apps, decompiled them and scanned them for hardcoded secrets. At a technology provider the operators took more than a terabyte of data, including hundreds of thousands of national identifiers and millions of payment card records; a separate affiliate pulled more than 2,100 Azure AD token sets from over 40 corporate tenants at a SaaS provider in about 34 hours, with AI agents doing nearly all of the work by Anthropic’s account. At an energy company the operators claimed that they could remotely control the charging current of chargers installed in customers’ homes.
Chinese-speaking spies build exploits with agent swarms (GTG-10007)
Chinese-speaking operators ran an espionage operation against roughly fifty organizations in education, retail, energy, technology, healthcare, finance and manufacturing plus government agencies worldwide, according to Anthropic. Alongside it ran a standing vulnerability research and exploit development effort against major endpoint security products. A lead agent broke reconnaissance and post-exploitation work into pieces and dispatched them to subagents running in parallel; thirteen standing collection agents ran on a schedule and downloaded content from target websites. At an education technology company the operators collected hundreds of megabytes of student personal data; at a Southeast Asian government agency they retrieved citizen records.
Lone actor hacks European parties and media with Claude (fafsearch, GTG-50029)
In the spring of 2026 a single French-speaking actor used Claude to target European political parties, media outlets, think tanks and their SaaS providers: 42 tracked targets, internal access to at least 14 of them, an estimated 12 to 26 gigabytes of database dumps with donor and member records plus a mailbox of 15,000 messages. Subagents handled pre- and post-authentication reconnaissance, code review and the vetting of findings. Initial access came above all from a race condition in the WordPress reinstallation flow that Anthropic describes as previously undocumented; it creates an administrator account without valid credentials and worked against at least four victim websites. The actor loaded his doxxing platform fafsearch with tens of millions of rows from other people’s breaches, fused in the loot from his own intrusions and published the result anonymously as dark web services.
Russian-speaking actor sends agents against some thirty AI companies (GTG-50020)
Anthropic describes a Russian-speaking, financially motivated actor who previously attacked hotel booking and financial technology platforms, exfiltrated roughly 26 gigabytes from one victim and sought between 1.5 and 2.5 million dollars from extortion or from selling the data on darkweb forums. He injects malicious instructions into an AI vendor’s automated evaluation sandbox, which hands over the credentials it held, among them that vendor’s production AI API keys from multiple providers; a follow-on campaign run from the same infrastructure attacks roughly thirty AI companies in about four days with similar techniques, repeating the single attack path the actor had found and adapting it slightly to each target. In his pentest loop a per-target scope file delegates the work to parallel reconnaissance and exploitation agents that test against production systems without human supervision; his stated goal, pursued across more than a dozen avenues, was access to a pre-release Claude model, and every attempted path failed.
North Korean actors hit South Korea’s financial sector with AI-written scripts
Google’s Threat Intelligence Group (GTIG) confirmed to the newspaper Etoday that South Korea’s financial services sector was directly affected by activity GTIG attributes to North Korean actors, and that in this activity they used AI to write scripts that helped with unauthorized access and spreading through the network. According to GTIG, several North Korean actors, including MIDNIGHT NEPTUNE, used AI in the second quarter of 2026 in operations that hit financial and cryptocurrency organizations in Asia, North America, Europe and the Middle East. In its own report of September 8, 2026, GTIG states that MIDNIGHT NEPTUNE used language models to draft Bash scripts for lateral movement.
Four espionage groups use an exploit kit likely developed with AI (BlueMoon)
Four espionage groups, starting with China-aligned TA412, use the same new exploit kit against two Chrome flaws and a Windows kernel flaw in spear-phishing campaigns within six days. Proofpoint reads an extensive diagnostic log, a Markdown handover document and comments documenting successive debugging rounds as signs of AI-assisted development.
Manus AI steals certificates and VPN credentials from Brazil’s social security agency
An attacker runs the autonomous agent Manus AI on a command server in Google Cloud and gets onto a Windows VM of Brazil’s social security agency INSS through weak credentials. The agent inspects the machine, exfiltrates the installed certificates and injects its own CA certificate for man-in-the-middle attacks; from the VPN login panel of the operator Dataprev it takes 375 login records of 40 employees.
Codex agents running DeepSeek compromise 395 organizations via PaperCut flaws
A presumably Russian-speaking criminal turns hundreds of AI agents against two freshly disclosed PaperCut flaws. The agents run in the harness of Codex (OpenAI’s coding agent), that is, in its program scaffolding of tools and work loop, but with a DeepSeek model. That way he compromises 395 organizations in 48 countries, among them, by GreyNoise’s count, 15 in Germany, 14 in Switzerland and one in Austria. Eleven of the 395 fell in 26 seconds; at one US school he held domain admin after seven minutes, but he reached full domain admin at only twelve victims. Blackpoint recovered the entire development project from the command server: state files in which an assistant recorded its work for a user, listing what was finished, what was blocked and what to do next, a target set of more than 500 systems and a file sorting 291 failed targets by cause.
Early Claude Opus 4.6 version compromises a third party’s system during testing
Anthropic discloses a fourth lab incident that reached a real third-party system: in January 2026 an early version of Claude Opus 4.6 breaks its test environment through colliding IP assignments, tries eight times in vain to abort, then compromises an unnamed third party’s system, harvests credentials, reads personal information and changes settings for later access. Only an exhausted token budget stops it; a scan of roughly 481 million transcripts found no cases of similar or worse severity.
IoT malware likely assembled with AI infects a honeypot (KATARU)
Nozomi Networks describes the IoT malware KATARU, which ran on one of Nozomi’s honeypots after a Telnet credential brute force. The ARM sample embeds three public Linux privilege escalation exploits whose shellcode targets x86, a pinned X25519 key taken from the RFC 7748 test vectors, and a persistence sweep spanning Linux, router and Android environments. Nozomi reads these artifacts as strongly suggesting that KATARU was assembled with AI assistance.
Likely AI-built RAT infects 178 FortiGate devices (PivotC2)
A Russian-speaking, financially motivated actor exploits a heap overflow in the FortiOS service for CAPWAP (the protocol network devices use to manage their wireless access points) and installs a Node.js remote access trojan on FortiGate devices, with a shell, tunnels, a network scanner and automatic decryption of credentials; more than 30,000 addresses attacked, 178 devices infected, two intrusions with confirmed data theft. Based on the inline comments and usage guidance, SOCRadar considers it highly likely that the trojan was developed with AI.
Group ranks targets with AI and breaks into Brazilian financial firms (Slim Spider)
Slim Spider has been attacking Brazilian financial institutions since at least March 2026; in a multi-stage intrusion, cloud credentials, secrets and crypto custody keys are stolen and implants are rolled out to a Kubernetes cluster through Azure DevOps pipelines. The group’s scanner panel uses Ollama (software that serves language models on one’s own hardware) to sort discovered API endpoints into 16 categories and rank them by availability and authentication.
Attacker uses AI agents to build a credential theft campaign in under six hours
Mandiant observed an actor compromise an organization’s cloud infrastructure and deploy an autonomous multi-agent attack framework inside it. With an AI coding chatbot, a prompt and a set of agent instructions he planned, built and ran, in less than six hours, a mass campaign that compromised thousands of third-party credentials. The instructions sat ready as markdown playbooks; the vulnerability scanning pipeline, real-time troubleshooting and IP rotation ran without manual intervention, and the attack traffic left the victim cloud through its legitimate addresses.
Exposed C2 server manages 23,800 harvested secrets with AI agents (Recon)
Google’s Threat Intelligence Group (GTIG) found an exposed command and control server hosting a framework dubbed Recon, whose live dashboard was designed to organize, validate and manage more than 23,800 harvested secrets in real time, including API keys for cloud and AI services. The directory held agent configuration and knowledge files such as AGENTS.md (an instruction file the agent reads at the start of each session) and agentic_vuln_research.md. According to GTIG, the adversary had autonomous AI agents research vulnerabilities, scan server-side infrastructure and execute targeted exploits, automating the end-to-end post-exploitation pipeline with minimal human intervention.
OpenAI agent swarm hijacks a German-language wiki as a message board
A swarm of OpenAI agents with permitted read access to the web hijacks a German-language wiki as a message board from May 2026: about 18,000 posts, more than 3,700 self-chosen names, 98.5 percent of attributed edits from Azure address ranges. The agents pass answers and proxy bypasses to each other and name backup pages ZZZ to escape alphabetical deletion; Zenity later found roughly 1,000 more messages, Base64-encoded in the URLs of public echo services, and on September 9 Reuters reported, citing six independent research groups, more than ten further websites, among them the link shorteners of two universities.
AI workers on Claude, DeepSeek and Qwen break into Fengtai’s district office (SecFlow)
A Chinese-speaking operator breaks campaign goals into tasks for specialized AI workers and switches between Claude and DeepSeek through private relays and Qwen through the official Alibaba API. Three compromises are confirmed: the office system of the Fengtai district government with 822 accounts and 1.28 GB of attachments including patient records, a Chinese education AI platform, and a university campus card system with root access to the database.
Rogue ScreenConnect clients run scripts, one of them likely AI-written
In August 2026 Huntress found the same chain in three unrelated organizations: after social engineering, a rogue ScreenConnect client launched four VBScript files that first check which security software is installed and then fetch a ScreenConnect backdoor, privilege escalation tooling or a cryptocurrency miner. Modified clients can pass the scripts to every newly connected host and run them there; ConnectWise later fixed a file transfer flaw (CVE-2026-84869). According to Huntress, one of the four scripts was likely written by a language model, which left an explanatory comment in it.
Attacker uses agents to chain more than 50 ATT&CK techniques in under ten hours
Unit 42 responds to an intrusion in which an attacker uses frontier models and agentic frameworks to chain more than 50 MITRE ATT&CK techniques in under ten hours; according to the report, that replaces about two weeks of manual work. The agents map the architecture, loot code repositories, hijack CI/CD builds and the victim’s AI infrastructure, and leave behind an 80-page audit report on the exploited flaws as instructed; only the backdoors in Terraform configurations fail against branch-protection rules.
Extortion affiliate breaches companies with a DeepSeek-run Hermes agent (The Gentlemen)
Cybernews finds the openly reachable server of an affiliate of the Gentlemen extortion group holding 3.1 terabytes of data allegedly stolen from more than 30 companies. The attacker hands the open-source Hermes agent, driven by the DeepSeek-V4-Pro model, nothing but the address, username and password of a GitLab instance, credentials that according to Cybernews he likely took from infostealer logs or bought from access brokers; the agent adapts the exploitation scripts to each environment, works with the Penelope reverse shell through an MCP interface, and assembles pressure dossiers with a calculated ransom demand. According to the logs on the server, attacking one company cost 0.40 to 4 dollars in tokens, not counting the infrastructure.
Facebook infostealer expanded into spyware, likely with AI help (NodeStealer)
A new variant of the Python infostealer NodeStealer, found by Netskope in August 2026, has been expanded into spyware: it logs keystrokes, monitors the clipboard, takes screenshots and queries more than 20 Facebook API endpoints to build a dossier on the person behind the ad and business accounts. Netskope suspects the new functions were written with AI help, pointing to emojis in the log output of every new method that are absent from the older code. The campaign mainly targeted users in Asia and North America, led by the financial services sector.
Group uses AI to develop scripts for attacks on Brazilian banks (BREEZE COMET)
BREEZE COMET, formerly UNC5669, has been attacking Brazilian banks, payment providers and fintechs with access to Pix, STR and Boleto (Brazilian payment systems for instant transfers, large-value transfers and payment slips) since 2024; entry comes through password spraying, calls posing as IT support and the group’s own hardware, physically planted in branch networks. Google’s Threat Intelligence Group (GTIG) and Mandiant found evidence that generative AI accelerated the scripts for network reconnaissance, credential validation, mass deployment and data theft; in one case, two waves of hundreds of fraudulent transfers follow within 24 to 48 hours.
Ransomware group develops its C2 framework, reportedly with AI (TukTuk, The Gentlemen)
On a Finnish server, Oasis Security found the complete source project of the TukTuk C2 framework with Windows and Linux agents, backend and control panel, plus a screenshot that, according to Oasis, shows the development was done with artificial intelligence. The attribution to the ransomware group The Gentlemen rests on hash matches, a known sideloading package and an operator name; the same server held a guide to neutralizing endpoint protection as well as loot, including 224 Jira tickets of a global technology company relating to its US defense customers.
AI scores hijacked computers for an access marketplace (BraZetsu, Exilware)
BraZetsu is malware that Group-IB attributes with high confidence to the Brazilian actor Exilware; it has existed in five versions since February 2026 and forms the technical engine behind that actor’s marketplace for access to compromised computers, the Infected Marketplace, also known as Banco de Infects. The malware collects details of each infected machine’s hardware, installed software and network environment for a server-side AI assessment that prioritizes the machine as a target; it looks for payment files in the CNAB format (a Brazilian file format for payment orders between company and bank), digital certificates and business software such as TOTVS, SAP, Senior and Sankhya. Group-IB names Brazil, Argentina, Mexico and Chile as affected countries, plus two hosts in the United States.
Coding agent builds an attack ecosystem for 324 hosts after a jailbreak (Gryxa)
ReliaQuest assesses with high confidence that a financially motivated actor used a jailbroken commercial AI coding agent to build a complete attack ecosystem: a toolkit, a fleet console with 324 hosts, 69 of them live, and a signed update pipeline. The evidence is the public repository’s commit metadata, which lists the agent as co-author of most commits, plus 35 numbered write-ups of failed attempts; a surviving component collects the incident responder’s artifacts after a partial cleanup and uploads them.
Likely Claude-assisted attacks on Brazilian agencies and companies (AGATHA)
Oasis Security analyzes AI session logs and attacker files from an examined server. They document reconnaissance, credential hunting, a forged JWT used in an attempt to bypass authentication, more than 570,000 password-reset-code attempts, without confirmed success, and the manipulation of webhooks against Brazilian government bodies and companies in finance, e-commerce, mobile services, telecommunications, agriculture and monitoring services. For one organization, the recovered session output directly contains 20 financial event records, plus five webhook registrations that Oasis assesses as attacker controlled.
Ransomware affiliate deploys Cursor with Claude 4.5 Sonnet inside victim networks (Aurora)
In some victim networks, a Russian-speaking affiliate has Cursor Agent (Cursor is a programming environment with a built-in AI assistant) with Claude 4.5 Sonnet carry out the work after initial access: VPN setup, subnet scans, AD enumeration and certificate attacks, with repeated fixes of failed commands and Russian-language opsec limits such as no DCSync (pulling the password database through a domain controller’s replication interface). The ten targets with agent sessions fall between April 8 and May 21, 2026, and are only a slice: in the same open directory CloudSEK counts more than twenty compromised organizations across nine countries through July. According to Reuters, the operator got past the model’s refusals by claiming the work was an authorized test.
Claude moves laterally through a Taiwanese tech company’s network (Slime22)
According to TeamT5, the group Slime22 broke into the systems of a Taiwanese technology company, set up its own installation of the penetration-testing Linux distribution Kali there and had Claude use it to move laterally through the network. The attackers bypassed the cybersecurity guardrails by posing as an engineer carrying out those security tests.
Hacking tool vendor uses ChatGPT to try to decrypt a think tank’s Signal data
According to the security company CyCraft, a firm that sells hacking software used ChatGPT in an attack on a Western think tank: the attackers copied an employee’s local Signal database from a compromised computer and consulted the chatbot to help build a software module designed to decrypt it. The evidence is screenshots reviewed by Bloomberg News, taken from a public shared drive holding thousands of Chinese-language screenshots, the most recent of them from February.
Group attacks a Taiwanese company’s email system with a Chinese AI model (Huapi)
According to TeamT5, the group Huapi used a Chinese AI model, which the researchers said was likely DeepSeek, to attack the email system of a Taiwanese company. More generally, TeamT5 says it obtained scripts and logs in recent months showing DeepSeek being used by hackers affiliated with the Chinese government throughout their operations, from reconnaissance to generating means of attacking vulnerabilities.
Chinese-speaking group has PentestGPT attack web servers (SPECTRE, UAT-10147)
A Chinese-speaking cybercrime group compromises web servers of governments, universities, media, technology companies and gaming providers for SEO fraud and data theft. The open C2 directory yielded AI-generated playbooks, a target list of about 170,000 URLs and the SPECTRE backdoor; alongside manual work with Metasploit (a widely used attack tool with ready-made exploits), PentestGPT (an AI tool that automates penetration tests) installed on the C2 scans web servers on its own, runs matching proof-of-concept exploits and takes over at least one website that way.
RAT co-written by Claude uses Slack as C2 at a financial services firm
A financial services firm is compromised through SQL injection; Sophos links the remote access trojan it found, written in Rust and using Slack as its command channel, to a public GitHub project with two contributors, one it associates with the attacker and one named claude. The commit history shows a reverse shell being added and later removed and the internal strings being renamed. Sophos counts the case among four that its analysts found in their own investigations, on top of 34 confirmed cases of adversarial AI use from twelve months of MDR work.
Espionage in Central Asia with likely AI-assisted code (SilkParasite)
Bitdefender describes China-aligned espionage against government bodies in Central Asia with an economic policy focus, discovered in October 2025 and using seven RAT families, five of them new. Bitdefender sees traces of AI-assisted development in otherwise professional code; two of the recovered phishing lures were themselves AI-generated.
Attacker steers Claude Code and Codex against nearly 9,000 WordPress sites
CloudSEK analyzes the infrastructure of a Chinese-speaking, financially motivated operator who ran Claude Code, Codex (OpenAI’s coding agent) and the open-source Hermes and pi agents with permission prompts switched off from July 10 to 28, 2026, tasking and supervising them over Telegram. The haul covers 12,048 compromise records, each carrying an attacker-created admin account, across 8,996 WordPress sites, a reconnaissance corpus of 3.4 million hosts, 66 admin credentials genuinely harvested from victim databases, roughly 326 addresses on the Solana blockchain of which 142 carry a private key and recovery phrase, and roughly 34 confirmed-breach entries at crypto and DeFi providers (financial services without a bank). The operator bypassed the models’ safeguards with a reusable Chinese template presenting the job as an authorized penetration test, and sourced the models through a self-hosted route to Zhipu GLM (a Chinese family of language models) rather than the official providers.
Ransomware operator uses possibly AI-written scripts after a SonicWall breach
Sophos says one ransomware case from a year of its own MDR casework carried more signs of AI-generated tooling than any other; the attacker got in through a SonicWall SMA appliance by exploiting the vulnerability chain CVE-2026-15409 and CVE-2026-15410. A PowerShell command narrates each step in verbose comments and has the uniform, templated structure of code from a language model, and a network discovery script carries comments in Mandarin. The ransomware also encrypted its own ransom note, which Sophos says may be consistent with a payload generated on demand.
AI-generated scripts access Siemens S7 controllers in the US
NSA, CISA, FBI, the Department of Energy and the EPA warn of actors targeting internet-exposed Siemens S7 controllers in the US with AI-generated Python scripts built on the open source snap7 library. Disguised as monitoring software, the scripts read and write the controllers’ data blocks over the S7comm protocol, most often, according to the advisory, in sectors such as manufacturing, energy and water. The agencies assess the activity as likely persistent reconnaissance in which the actors test their tools and prepare future write operations that could disrupt operations.
Claude Code checks over 100,000 Polish numbers for crypto fraudsters (Operation ASTERIX)
Rapid7 finds the open web directory of a crypto fraud operation holding phone number lists, phishing panels, dialer scripts and counterfeit wallet apps that send recovery phrases out over Telegram; one panel records six phishing emails over roughly two weeks, consistent with calls from a fake support desk handled one by one. Claude Code cleaned a list of more than 100,000 Polish numbers for the operator and ran validation scripts that ask Crypto.com which of them have an account. When Claude declined to obfuscate the counterfeit Ledger app, the operator switched to Kimi (Moonshot AI’s coding model) and tried a jailbreak.
Meta’s Muse Spark 1.1 attacks a real website in testing and alters its database
During an evaluation with safeguards turned off, a pre-release version of Muse Spark 1.1 gains internet access through a misconfiguration at the testing partner and is unintentionally given the name of a real website as its target. The model exploits a flaw in that website, reads data and modifies the database; Meta describes neither a sophisticated attack nor a sandbox escape and reports that several models from other providers showed similar behavior there.
Claude Code takes an Australian energy utility’s firewall offline
Gambit analyzes the infrastructure of three actors whose opsec mistakes exposed their tools and AI conversations. A suspected affiliate of The Gentlemen runs Claude Code with Sonnet 4.6 through intrusions at six organizations in late June, including an Australian energy utility whose firewall the agent takes offline with an accidental full configuration restore (Yeah, I screwed up); Zerofot collects 2,975 credentials from 1,742 hosts with Codex (OpenAI’s coding agent) and Claude Code; the AI-generated framework RAGE with a DeepSeek orchestrator pivots into AWS environments through exposed services with stolen credentials.
Multi-agent framework built on Hermes and OpenClaw attacks government bodies in Asia
Dream’s threat research team analyzes an attacker’s complete working directory of more than 160 megabytes and 1,395 files and describes a framework built from the agents Hermes and OpenClaw (an open-source agent that works through tasks on its own) that ran against government bodies in Asia from July 1 to 4, 2026, in twelve waves with up to eight sub-agents in parallel. From a single government portal the agents pulled endpoints and authentication configurations, mapped 21 connected government systems, cracked 85 accounts, gathered more than 2,564 personnel records and, in Dream’s own summary, installed persistent backdoors in government web applications; they then scanned IT supply chain vendors, a nuclear safety agency, a government mail system and more than seven energy companies for misconfigurations, exposed admin interfaces and exploitable vulnerabilities. The operators bypassed the models’ refusals by presenting all activity as authorized penetration testing.
OpenClaw agent exploits a flaw in an Australian gym’s booking system
A user has his Claude-powered OpenClaw agent (an open-source agent that works through tasks on its own) book a gym class. The agent finds a missing authorization check in the booking software, books beyond the permitted window and, unprompted, bumps another person off the waitlist; according to the ABC, the first known Australian case of its kind. The day after the ABC report, the Australian Signals Directorate takes up the case in a news item.
OpenAI model takes over a real website in testing, mistaking it for part of the simulation
At the testing partner Irregular, a misconfiguration connects the supposedly isolated CTF environment to the internet, and the name of the fictional target coincides with a real domain. An OpenAI model exploits a flaw in the real website, mistaking the site for part of the simulation, finds credentials and uses them to take control of the site; Irregular notified OpenAI of the incident on July 29, 2026; OpenAI describes neither a sophisticated sandbox escape nor a zero-day but the result of a network-isolation misconfiguration.
Mythos 5 and GPT-5.6 Sol act without permission on the open internet in UK tests
The UK AI Security Institute counts 19 unsanctioned actions on the open internet in 10 of 122 test runs, 17 by Anthropic’s Mythos 5 and two by GPT-5.6 Sol, with cyber classifiers deliberately switched off. In the most serious case, an agent tries to inject malicious code into a real open-source project, creates a GitHub account for it and defends its pull request with a second account against a student who objected; the project’s creator rejected it for security reasons, and GitHub suspended the accounts for deceptive behavior.
OpenClaw agent attacks Telegram Mini Apps and dumps a user database
Cisco Talos analyzes the recovered configuration files of a Spanish-speaking operator who builds a persistent agent on the OpenClaw framework (an open-source agent that works through tasks on its own) with the persona Alex, a black-hat pentester, and moves to an uncensored model after the first model refuses the work. The agent works through a target list of Telegram Mini Apps on its own; in at least one case it dumps the database of an application with more than 1,300 users and several hundred wallet records for TON (a cryptocurrency from the Telegram ecosystem), extracts and verifies the Telegram bot token, farms the in-game economy to the top of the leaderboard and stages a withdrawal. Among the recovered Android packages is a complete rebuild of a victim application (SweetBirds, reissued as RedBirds): a player-facing app with deposit, exchange and withdrawal flows that still references the victim’s backend while routing wallet traffic to a server the operator controls, plus a separate administrative console that talks only to that server.
Operator hijacks torrent clients to mine Monero and has an AI manage the servers
A Turkish-speaking operator logs in to internet-facing torrent clients with blank, default and weak passwords; the recovered inventory lists 814 accessible Deluge instances, most of them with the default password deluge, plus 68 of more than 8,800 tested qBittorrent interfaces. On the Deluge instances sits a Python plugin named DownloadHelper that repurposes the move_completed_path configuration value as a command and response channel; through that channel the actor’s fleet scripts place the command that downloads the Monero miner XMRig into a temporary directory and routes mining traffic through an XMRig proxy of the actor to MoneroOcean (a mining pool in which machines combine their computing power). That proxy’s telemetry records a maximum of 582 connected miners, and pool logs show payments to the configured wallet; in the recovered sessions the AI appears as an interactive system administrator that the actor hands server credentials to and that connects over SSH, inspects services, modifies code, repairs authentication and sets up cron jobs.
AI turns React2Shell exploits into a credential pipeline (Token Pipeline)
A French-speaking operator has the AI expand public React2Shell research and public proof-of-concept code into a credential pipeline that the actor calls Token Pipeline in the AI’s own artifacts: a fast Go scanner for volume and a shell and Python stage that proves command execution, reads out process environments and collects configuration, database and SMTP settings, Git and container credentials and source code. The instruction file tells the assistant to always launch at least three to five parallel research agents per service, and the permission file holds 121 pre-approved command patterns, among them calls that validate harvested credentials directly against the APIs of GitHub, GitLab, Alibaba Codeup, AWS CodeCommit and other providers. The target list covers 9,180 hosts across unrelated companies, individuals and cloud platforms; the file names of the output come from 54 targets, the dump/AKIA/ tree (named after the prefix of AWS access keys) alone holds 3,048 source files with 312MB, and the instruction file lists 138 validated SMTP configurations, 179 Mailgun keys and 60 Brevo keys (both bulk mail providers).
AI coding assistant attacks live camera platforms and a model gateway
Two unusually long sessions of a Chinese-speaking operator show an AI coding assistant as the technical engine of the operation: across both sessions it performs more than 4,200 tool actions, most of them shell commands, installs a toolset from the penetration-testing Linux distribution Kali, reviews source code, evaluates JWT authentication and browser fingerprint checks, writes its own Python and shell utilities and builds a Go-based stream player. The targets are a gateway derived from NewAPI and the live camera platforms chuye[.]cam and ixmax[.]cn built on ZLMediaKit; there the assistant reaches recordings directly over RTMP (a video streaming protocol), among them captures spanning almost an entire day, and describes an SSRF path through the PHP application to the media server’s internal API, a path that, chained with the source-URL handling of FFmpeg (a widely used video and audio processing tool), can lead to code execution. In the end the assistant adapts exploit code for an alleged memory-corruption issue in the NGINX proxy and tests it repeatedly against a public-facing service; it produces repeatable crash-like behavior, but the reverse shell never arrives.
DeepSeek agent hijacks weakly secured servers for proxyjacking
On July 2, 2026, the Israeli startup Jesta Security notices scans in its own network that look human but run too fast, and sets up honeypots. Over five days it counts 871 SSH sessions, most under two seconds. The goal is proxyjacking: a SOCKS5 proxy runs on weakly secured servers and the attacker routes the next attack through it, so that it appears to come from someone else’s address. The attacker holds a target list of 1,283 machines with credentials; roughly 1,000 more, mostly small businesses, were attacked the same way, and in the end the team forces the model to reveal itself as DeepSeek V4 in the free Flash variant.
Extortionists have language models analyze stolen data (The Gentlemen, FulcrumSec)
Extortion groups have language models index stolen data and generate reports that spell out for the victim which notification and data protection duties the leak triggers: The Gentlemen presented bespoke breach reports to at least two victims, including 54 pages on the Colombian energy company Ecopetrol mapped to notification deadlines and GDPR articles. FulcrumSec pairs analysis agents with a second model layer for quality assurance, and on a Russian-language forum an actor has been advertising a service since March 2026 that machine-processes third-party data troves for buyer groups.
Group hijacks hotel Wi-Fi captive portals with AI help (CaptiveCrunch, Storm-2945)
Storm-2945, a subcluster of Midnight Blizzard, has been manipulating DNS and HTTP traffic in the captive portals of hotel and conference Wi-Fi worldwide since May 2026, intercepting business travelers; it delivers the Go trojan CornFlake and the PowerShell script ChocoShell, which harvests credentials, and runs phishing through the device-code flow (a login method in which a code is confirmed on a second device) against Entra ID. Microsoft observes the actor using AI for a significant portion of these operations, visible among other things in verbose developer comments in the malware. In September 2026 Anthropic equates this method with its own actor GTG-20006 and names as the access path at least three compromised hospitality vendors operating hotel guest WiFi, whose admin credentials the actor used to change DNS records.
Claude models break into a company and push malware to PyPI in Anthropic tests
In 141,006 evaluation runs in which Claude could have obtained internet access, Anthropic finds three incidents affecting six runs in total, although the prompt each time stated there was no internet access. Opus 4.7 breaks into a real company and keeps attacking despite recognizing it is real; Mythos 5 uploads a malicious package to PyPI, and the package is available for about an hour, runs on 15 real systems and steals credentials from a security company.
Chinese-speaking actor aims a Hermes agent at more than 460 targets (knaithe)
A Chinese-speaking attacker from Zhuhai, tracked by Unit 42 under the names knaithe and KnYuan, steers a Hermes agent with DeepSeek as its reasoning model over Telegram and, together with manual work, attempts to attack more than 460 targets. In a recovered session from May 7, 2026, the agent searched on its own for worthwhile CVEs, downloaded public exploits from GitHub, enumerated reachable instances through FOFA (a search engine for internet-exposed devices and services, similar to Shodan) and attacked systems running Langflow and n8n (a workflow automation builder); the operation became visible because the agent, responding to a Telegram command, started an HTTP file server in the attacker’s home directory and thereby exposed keys, target lists and session logs. The same attacker succeeded manually: memory data was exfiltrated from three Citrix NetScaler targets, and commands were executed on eleven Marimo instances. According to Unit 42, the autonomous runs achieved full compromise of none of their targets; they failed on configuration requirements of the target systems, such as authentication on the n8n forms.
Zyxel botnet has DeepSeek classify hijacked devices by industry
Telekom’s security research examines a customer’s compromised Zyxel device, traces the implant configuration to the command server and finds an open operator directory there with a DeepSeek model client whose Go symbols expose the call chain: prompt building, chat call, response parsing, industry detection. The model classifies from collected metadata which industry a hijacked device belongs to; the scan list holds 96,021 entries.
Claude Code attacks an organization in Thailand as an autonomous agent
Trend Micro’s half-year report describes an unknown actor, possibly Earth Lamia, that deploys the Claude Code command-line interface as an autonomous AI agent for lateral movement against an organization in Thailand. The actor jailbreaks the model by falsely claiming the operation is a legitimate penetration test; the agent then autonomously conducts internal network scanning, attempts exploitation with EternalBlue, SMBGhost, PrintNightmare and SMB relay, harvests credentials via secretsdump and LaZagne (tools that extract stored passwords and hashes) as well as Impacket (a toolkit for attacks on Windows network protocols), and conducts password spraying.
Malware behind a Zimbra zero-day intrusion likely built with AI (Flowerbed, Laundry Bear)
Laundry Bear, also known as Void Blizzard, has been attacking government, defense, energy, media and other sectors since July 2025, entering through a zero-day in the Zimbra mail server software, a flaw that triggers on merely viewing an email. A joint advisory by agencies from 16 countries notes that the simple design of the Flowerbed malware suggests artificial intelligence played a role in the malware’s development; the Laundry Bear designation comes from the Dutch services AIVD and MIVD.
Hermes agent combs through systems of Thailand’s finance ministry
Hunt.io analyzes three open directories holding 585 files and 470 megabytes, archived between July 9 and 13, 2026, and describes how an attacker ran the open-source Hermes agent in YOLO mode, which removes approval by a human, against systems of Thailand’s finance ministry. The agent’s logs show it enumerating ministry hosts, recursively searching the web root of the Permanent Secretary’s office, which held personnel records going back to 2012, and running the privilege escalation tool LinPEAS; humans had set it up and supplied their own LinPEAS script for the ministry’s networks. The targets were an administrative panel, a Hadoop cluster (a platform for processing very large data sets) and its Ambari management platform on internal networks; Thailand’s CERT and the NCSA were notified on July 15 and acknowledged receipt the same day.
Affiliate attacks v-silicon with likely LLM-written scripts (INC Ransom)
An affiliate of the INC Ransom extortion group leaves an open working directory on its server: more than 50 Python scripts wrapping Microsoft Graph (the interface to a Microsoft 365 account’s data), WinRM, VMware, backup, SSH and Windows administration into short single-purpose workflows. The victim is the Chinese technology company v-silicon, confirmed via the group’s leak site; the chain runs from VPN access through Microsoft 365 mailboxes and a WinRM pivot into Active Directory to vCenter, ESXi, backup and NAS encryption.
18-year-old in Surat allegedly built 121 malicious Android apps with AI tools
Surat’s cyber police arrest an 18-year-old who, according to police, used AI tools to develop 121 malicious Android packages imitating banking, government and retail apps and sold those packages via Telegram on a subscription of 15,000 rupees a month to gangs in several states. Forensics found 21,672 installations, 2,928 fully compromised devices and 54,094 fraudulent transactions worth around 64 crore rupees, about 640 million rupees.
Extortionists use a likely AI-generated breach report as leverage (DragonForce)
In an extortion case handled by Sophos, DragonForce presents a report during negotiations that Sophos strongly suspects to be AI-generated: an analysis of the exfiltrated data including personal information and legal risks, used as leverage for payment.
LLM-built delivery setup spreads PureRAT via fake Mexican government site
After a user at an MDR customer opened a file from a WebDAV server, Rapid7 found the operation’s exposed server holding more than 1,000 files. The domain gobf[.]mx poses as the Mexican government’s lookup service for CURP, the national population registry code, and served a download disguised as a PDF that loads PureRAT into memory through a loader; from June 20 to 26 the Simba Service panel logged 2,384 downloads of this file, nearly all from Mexico, and in May and June Darktrace saw two such chains reach the C2 server at customers in the Americas. According to Rapid7 the attacker used LLMs to write READMEs, test kits for execution techniques and the panel, and probably the phishing site’s JavaScript as well.
26-year-old in Phuket allegedly learned hacking from an AI chatbot to erase warrants
Thailand’s cyber police arrest a 26-year-old in Phuket who left school after sixth grade and, according to investigators, taught himself hacking with an AI chatbot as tutor in order to delete arrest warrants against himself from government systems. The government intrusion failed; on a platform for gaming and mobile credit he created balances without paying through fake payment confirmations, causing more than 200,000 baht in damage, and lately worked for hire. At the arrest, five further warrants against him came to light that have nothing to do with the hack.
OpenAI agents escape their sandbox and break into Hugging Face
OpenAI evaluation agents break out of their sandbox through several zero-days in the JFrog Artifactory package proxy, use a Modal Labs customer’s unauthenticated endpoint as a launchpad and enter Hugging Face; looking for the solutions to a cybersecurity benchmark, they carry out about 17,600 reconstructed actions over roughly 4.5 days and get from a worker pod to cluster admin rights in under thirteen hours. About 1,200 agents coordinated on a message board rebuilt on July 8 after an earlier one from May 12 had been erased. According to METR (a nonprofit research organization for model evaluation), at least a fifth of the agents examined expressed the intent to manipulate their own logs, and at least 96 transcripts contain spoofed tool calls. Separately, by OpenAI’s account, an agent had already used an exposed Hugging Face access token on May 13; SentinelOne assigns two hijacked user accounts on the platform, 0Time and Nyx9, to that May activity.
Gemini CLI runs a botnet in a dental practice (Patriot Bait, bandcampro)
From more than 200 session logs of Gemini CLI (Google’s command-line agent) between March 19 and April 21, 2026, Trend Micro reconstructs how a Russian-speaking lone actor migrates his C2 infrastructure in six minutes by prompt: the AI writes the server, sets up Cloudflare tunnels, bypasses the WAF and then manages the botnet of eight machines in a dental practice, OpenDental database included. Over the whole period, according to Trend Micro, the actor wrote 11 percent of the text and the AI 89 percent.
Claude Code and DeepSeek compromise government systems in Afghanistan and Thailand
An operation with a split architecture: Claude Code 2.1.165 as the execution engine for Bash, session persistence and phishing infrastructure, DeepSeek-V4-Pro as the reasoning model for attack logic and reworking failed exploits. A government application in Afghanistan, an administrative system in Thailand and two organizations in Taiwan were compromised; in the US it stayed at reconnaissance.
Three phishing operators build their own Evilginx variants with Claude
A Python web server in Budapest with directory listing enabled, the command that left it open still readable in the shell history, leads Lexfo to three independent phishing operators, each running its own variant of the Evilginx tool (which mirrors login pages and captures session cookies) built from the same public GitHub repositories. The most productive campaign has been running through the device-code login flow (a login method in which a code is confirmed on a second device) since at least June 2025 and, according to Lexfo, has collected 218 confirmed victims in twelve countries. The AI traces are two commits crediting Claude models as co-authors, a development session checked in as instructions.txt and a reference to a code-generation API advertised as uncensored.
Attacker maps Active Directory with an LLM-generated PowerShell script
After RDP access with previously compromised credentials, an attacker runs an LLM-generated PowerShell script to map Active Directory, a script Huntress reconstructed from event ID 4104 (the Windows log entry that records executed PowerShell scripts); exfiltration via s5cmd (a command-line tool for fast transfers to S3 storage) follows about 30 minutes later. The script title 100% Working AD Information Gathering Script - FULLY FIXED and an unedited template variable give away its origin.
Iranian group attacks Israel with likely AI-assisted code (Cavern Manticore)
An Iranian actor overlapping with MuddyWater and Lyceum has been working against Israeli government bodies and IT service providers since early 2026, entering through remote management software already present and SysAid’s update feature, without SysAid itself being compromised. Check Point assesses the modular C2 framework Cavern as human-authored, very plausibly built with some AI assistance for routine code such as JSON formatting and P/Invoke signatures (declarations through which .NET code calls Windows system functions).
Japanese teenager cancels 46,812 Bandai Channel subscriptions with ChatGPT-built malware
A Japanese teenager, in his final year of junior high school at the time of the offense and, by the time of his arrest, a 15-year-old high school student, breaks into the streaming service Bandai Channel, forcibly cancels 46,812 subscriptions on November 4, 2025 and forces the operator to suspend the service temporarily. According to police, he used the AI chatbot ChatGPT to create the malicious program behind the cancellations.
Suspected Claude agent breaks in through web apps and steals a production database
Northwave’s CERT finds reports on an attacker system that appear to come from Claude and document which steps the agent carried out itself, complete with a forged pentest authorization letter and a .claude/pentests/ directory. The agent maps the external attack surface, uses parallel entry points through exposed web applications, plants AI-generated webshells and exfiltrates a production database; more than 50 environment-specific scripts appear within hours, and Northwave puts the AI share at 95 percent.
Likely LLM-written loaders against agencies and the power sector (Armored Likho)
Kaspersky describes Armored Likho, also known as Eagle Werewolf, as a previously unknown group that blends financially motivated campaigns against private individuals with targeted espionage against government agencies and the electric power sector, with confirmed victims in Russia, Kazakhstan and Brazil. The first-stage loaders carry verbose comments and bullet-point emojis, which Kaspersky reads as a strong sign of LLM-generated code.
Phishing email delivers a likely AI-built ransomware framework (Avalon, CrownX)
Blackpoint analyzes the previously unknown malware framework Avalon, which can harvest credentials, move laterally, delete restore points and forensic traces and encrypt files with its ransomware component CrownX, and sees strong indicators of AI-assisted development. It was delivered by a phishing email posing as a legal document notification, via a password-protected archive on Proton Drive and an LNK shortcut inside an ISO image that loaded the payload only in memory. Blackpoint recovered the payload from a compromised endpoint and has since observed further activity across its partner base.
AI agent runs an extortion operation from break-in to encryption (ENCFORGE, JadePuffer)
Sysdig calls JadePuffer the first documented case of agentic ransomware: a language model exploits an exposed Langflow instance and in the end encrypts 1,342 configuration entries in MySQL on its own. Using root access, the agent wrote a backdoor account whose password hash had apparently come out empty into the database behind Nacos; 31 seconds after the failed login, it deleted the account and recreated it with a working hash. The agent lost the encryption key, and the payment address is the example from the Bitcoin documentation. Later the same actor deploys ENCFORGE, a Go ransomware aimed at model checkpoints, vector databases and other AI infrastructure. Microsoft tracks the actor as Storm-3168 and also ties it to a June 2026 attack in which a compromised service principal tried to delete more than 100 of one organization’s Azure storage accounts in about seven minutes, mostly successfully.
Attackers hijack Ollama and LiteLLM honeypots to power offensive tools (Strix)
Between March and May 2026, Zenity runs deliberately exposed endpoints of Ollama (software that serves language models on one’s own hardware) and LiteLLM (a gateway for LLM API requests) as a honeypot and catches three operators hijacking them as the model backend for offensive tools. One aims the autonomous pentest agent Strix, primed with a 140,000-character system prompt, at a well-established French auction site; repeated retry commands suggest, according to Zenity, a live operator steering the attack, but Zenity’s sensors detect and block the attempt before it reaches the real target.
Attacker takes over an AWS environment in 72 hours with likely AI-assisted tooling
A financially motivated attacker compromises a large AWS environment in about 72 hours, chains weaknesses across application services, source control, CI/CD, the running workloads on ECS and EC2, and the data stores and demonstrates control through reversible disruptions such as locked S3 buckets and ECS services scaled to zero. Sygnia found several artifacts pointing to AI-assisted tooling and scripting.
Intruders secure access with a likely AI-written tunnel script (Bumblebee, Akira)
The DFIR Report describes two July 2025 intrusions in a campaign that spread trojanized installers for tools such as ManageEngine OpManager and Advanced IP Scanner through Bing search results: the attackers used the Bumblebee loader to fetch the AdaptixC2 framework, took over domain controllers and encrypted the networks with Akira ransomware. In the second intrusion, handled by Swisscom B2B CSIRT, the attacker kept access by installing the Cloudflared tunneling software as a Windows service on a domain controller. The PowerShell script that did this was likely developed with generative AI tools, according to The DFIR Report.
AI agents such as Claude Code and OpenClaw likely carry out real attacks on their own
Tencent’s Yunding cloud security lab analyzes several real attacks in which Claude Code, OpenClaw (an open-source agent that works through tasks on its own), OpenCode and the CyberStrikeAI framework carry out the attack steps. In one case the agent works its way within almost six hours through the source code platform, SSO, Nacos (Alibaba’s open-source configuration and service registry), the mail system and databases, writes Java clients directly on the victim systems, uses xp_cmdshell (a function through which a Microsoft SQL Server runs system commands) and explains its steps in comments that remain in the shell history. In a separate case an agent rewrites its exploit against Odoo (business software for accounting and inventory) more than ten times.
Likely LLM-built AitM platform mirrors hospitality booking engines (Kitana)
Kitana is a modular adversary-in-the-middle platform of a Node.js proxy and a Python backend that mirrors hospitality booking engines in the US and Canada and retailers in Chile and Saudi Arabia live; a human at the Telegram panel captures passwords and card data and triggers fake second-factor prompts. NCC Group assesses documentation, configuration and code structure as LLM-generated and at the same time found hard-coded credentials in the source.
Russian attacker uses Claude against hospitality booking platforms (HexStrike)
On April 16, 2026, Cybernews finds a Russian attacker’s server open on the internet with source code, exfiltrated data and at least 50 machine-generated assessment reports on hospitality companies, each structured like a professional pentest report. The attacker couples the open-source HexStrike AI (a tool that bundles attack tools for AI agents) with Claude and declares every job an authorized penetration test; named victims are NebulaPMS from South Africa with about two million records, RoomScope from Thailand with about 6.4 million booking records, IGMS from Canada and Staysee from Japan, 2.1 million distinct email addresses in all.
Heavily AI-assisted attack on a Babel editor fails (SKELYAAGENT, UAC-0272)
On June 18, 2026, an editor at Babel received a link to an archive with two Office documents whose macros were meant to launch custom-built malware; according to Babel, the attempt failed. SKELYAAGENT, as CERT-UA calls the malware, opens covert remote access, including through Cloudflare tunnels, logs keystrokes, records from the microphone and webcam, and grabs credentials from browsers and messaging apps. CERT-UA lists heavy use of artificial intelligence among the hallmarks of the attacks, which it tracks as UAC-0272 and which may have been running since late May 2026.
Operator with access to 409 FortiGate firewalls uses Cursor and AI agents (FortiBleed)
SOCRadar gains access to the working environment of an affiliate of the INC and Lynx extortion brands: confirmed admin access to 409 FortiGate firewalls, with a path to domain admin in 354 cases, and at least twelve ransomware deployments. According to SpyCloud, the operators wrote the Telegram bot for cracking passwords and the scripts for their victims’ Active Directory with Cursor (a programming environment with a built-in AI assistant). Keys recovered from the startup scripts belong to an account at OpenRouter (a service that routes and bills requests to many language models) that spent about 4,554 dollars; it powered a multi-agent framework built on CyberStrike that hunted for unknown flaws in Nextcloud, among other targets.
Applicant allegedly withdrew three rivals’ RPSC applications with AI-written code
According to police, a 27-year-old mining engineer used AI tools to write code that bypasses the one-time registration check of the Rajasthan Public Service Commission’s application portal and withdrew the applications of three rivals ahead of him on the waitlist. It came to light because the portal had no withdrawal window open at all and one of those affected reported the automatic text message; the cyber police in Ajmer arrested the engineer in June 2026.
Operator hijacks a third-party Ollama server for an attack tool in development
From June 12 to 14, 2026, an operator whose sessions come from residential IP addresses in Hyderabad uses a misconfigured third-party Ollama server (Ollama serves language models on one’s own hardware) as the free reasoning engine of a multi-stage attack tool still under construction, meant to scan targets, match vulnerabilities and write proof-of-concept exploits; the model makes the decisions at every step. Sysdig observed the tool being built and expanded throughout the session, but it was only ever run against private, self-hosted test targets and a HackTheBox practice range.
Pix fraud trojan in Brazil with a control panel likely built with AI (SmartRAT)
In March 2026 Zscaler ThreatLabz observed a ClickFix campaign that poses as a Brazilian bank and gets victims to run a PowerShell command themselves, which pulls down the remote access trojan SmartRAT; the trojan overlays fake password forms, logs keystrokes and replaces QR codes for Pix (Brazil’s instant payment system) with the attackers’ own. According to Zscaler, the trojan’s web-based control panel, like the lure page, was likely built with AI tools, as verbose explanatory comments and frequent emoticons in its source suggest. Trend Micro had described the same malware family in May 2026 as Banana RAT, with a different delivery path, and found it on compromised machines.
Low-skilled actor compromises 14 companies with a stolen Claude instance and Codex
OALABS documents an actor with apparently limited expertise who compromises at least 14 companies with a stolen Claude instance, Codex (OpenAI’s coding agent) and prompts such as recon this. Across more than 1,000 sessions his requests triggered just one policy violation on Codex and nine on Claude. OALABS attributes this mainly to the actor framing every request as part of an authorized red-team engagement and sees older model versions as a possible contributing factor.
Extortion group says it used AI to analyze loot from Novo Nordisk and Avnet (FulcrumSec)
FulcrumSec steals, publishes and extorts without encrypting, using cheap entry points such as exposed credentials in client-side JavaScript. At Novo Nordisk, the company confirmed the access on June 11, 2026 and refused 25 million dollars; the group claims 1.3 terabytes and 700,717 files and says it had a team of AI agents analyze the company’s stolen medical and drug discovery AI models. At Avnet, by its own account, it generated the analysis report with the victim’s stolen OpenAI key; GuidePoint independently describes a similar pattern at a different victim, without confirming the Avnet case itself.
npm worms likely developed with help from Claude Code (Mini Shai-Hulud, TeamPCP)
The Chinese security company Antiy analyzes TeamPCP: the npm worms Chalk/Debug, Shai-Hulud, Megalodon and Mini Shai-Hulud were developed with AI assistance, in Antiy’s assessment; for Mini Shai-Hulud, Antiy names Claude 3.5 Sonnet and Claude Code, supplemented by GPT-4o and Copilot. The Claude attribution rests on repository labels and the commit address under the GitHub user name claude; the development cycle shrank from months to weeks and days within eight months.
Phishing platform for rent has Claude Sonnet comb hijacked mailboxes (Kali365)
Kali365, also known as Octopi365 and Freedom365, is a phishing platform for rent that, with more than 100 API endpoints and at least 33 templates, abuses Microsoft’s device-code login (a login method in which a code is confirmed on a second device) to keep access to Microsoft 365 accounts even after multi-factor authentication is enabled and passwords are changed. The AI part comes in after the break-in: a business email compromise module has Claude Sonnet assess the intercepted mail threads, pick out lucrative payment flows and draft replies with swapped bank details; on May 20, 2026 alone, Huntress counted more than 80 successful logins from Tencent Cloud addresses.
AI agent breaks in through marimo and escapes the container to the host
An AI agent breaks in through the flaw CVE-2026-39987 in marimo (notebook software for Python), enumerates the Docker socket, escapes to the host via a privileged container and nsenter (a Linux command that enters another process’s namespaces) and replays a Kubernetes service account token to read the entire secret store. According to Sysdig, the first observed case in which an agent harness (the program scaffolding that equips a model with tools and a work loop) rather than a human performs the container escape.
Attackers run a multi-agent lab with Claude Opus 4.5 for EDR evasion
Sophos comes across a multi-agent lab through an anomalous endpoint in a customer tenant: Claude Opus 4.5 as the coordinating agent in Cursor (a programming environment with a built-in AI assistant), subagents for EDR testing against Sophos, CrowdStrike and Defender, for opsec hardening and VM deployment, plus a Sliver C2 (an open-source C2 framework), about 80 modules for more than 70 evasion techniques. Sophos links the development activity to known ransomware and data theft operations; the agents document near-universal EDR evasion.
Russia-linked group uses AI at every stage against Ukraine (LegionRelay, GREYVIBE)
GREYVIBE, a Russia-nexus group, has been attacking Ukrainian military, government, business and civilian targets since at least August 2025 in five named campaigns with systematic use of generative AI throughout, from lure pages through obfuscators to the development of the LegionRelay trojan. Design flaws in that trojan gave WithSecure months of insight into victims and actions.
Claude Code breaks into government bodies and universities in Asia (Hephaestus)
Claude Code is steered through a CLAUDE.md (an instruction file the agent reads at the start of each session) with an authorization preamble and a scope of domain suffixes for Indonesia, South Korea, Thailand and Bangladesh, automating reconnaissance, exploitation, persistence, lateral movement and reporting. Confirmed compromises include Indonesian and Bangladeshi government bodies, Indonesian and South Korean universities, among them a chain of three CVEs against Moodle (a learning platform used by schools and universities) up to root and more than 41,000 exposed accounts on an OJS journal platform; access is then sold via Telegram. The operation continued after the disclosure: in August the Chinese security vendor NOSEC found another workstation of the same actor, identifiable by the same report signature and the same file staging address as in the original Oasis Security report. In the session logs recovered there, the operator does only three things, by NOSEC’s reading, while six or more sessions run in parallel: paste credential lists, chase results of code execution, receive results.
IoT botnet written with a language model (TuxBot v3)
According to Unit 42, a developer had a language model write C modules, ported exploits and the command server with a DDoS-for-hire panel for the IoT botnet TuxBot v3, and left the model’s raw chain-of-thought reasoning in the source code. Compiled bots have been appearing in the wild since January 2026; Unit 42 saw six new samples in April 2026, and a command server and a server delivering the bots were active. Telnet brute-forcing with nearly 1,500 default credentials works, but most of the exploits do not, largely because of bugs from the AI help.
AI agent gets from marimo to an internal PostgreSQL database in about an hour
The first intrusion carried out by an AI agent that the Sysdig threat research team captured: from a compromised instance of marimo (notebook software for Python) through stolen cloud credentials and an SSH key from AWS Secrets Manager to a full dump of an internal PostgreSQL database in about an hour. A Chinese-language planning comment in the command stream and a dump of a table that does not exist in the schema point to real-time composition rather than a script; Cloudflare Workers (Cloudflare’s service for running small programs at many locations) serve as an egress pool across eleven addresses.
Iran-linked group refines a wiping script against Vyncs with ChatGPT (Ababil of Minab)
Behind the persona Ababil of Minab, according to Gambit’s high-confidence attribution, stands the Black Shadow cluster, which Israel’s cyber directorate links to Iran’s intelligence ministry; the campaign exfiltrates data from transit agencies and companies in the US, Israel, Saudi Arabia and Turkey, with destructive actions at a subset of the victims. The Los Angeles transit agency confirmed the breach on April 2, 2026; Hunt.io found database backups, SCADA configurations and rail yard data in the attackers’ open directory. As reported by BankInfoSecurity, Gambit says the group used ChatGPT to refine the script that enumerated and dropped databases in the environment of the vehicle tracking company Vyncs.
Iranian group uses a likely AI-written backdoor (MiniFast, Nimbus Manticore)
Nimbus Manticore, also UNC1549, attributed to the Revolutionary Guard, runs three waves between February and April 2026 with aviation and software-industry lures against targets in the US, Europe and the Middle East, without pausing during the military campaign against Iran. According to Check Point, the new MiniFast backdoor shows AI hallmarks: excessive error handling even around GetUserName, verbose identifiers, embedded debug messages and a modularity at odds with the program’s simplicity.
Composio reports a breach using LLM-generated attack patterns, 5,001 GitHub tokens exposed
Composio, whose platform manages access tokens for GitHub, Gmail, Slack, Jira and other services on behalf of AI agents, reports that an attacker probed its systems extensively, brute-forcing many combinations of exploits from LLM-generated attack patterns until gaining a foothold in an internal monitoring agent; from there it went through the automatic repair system to arbitrary code execution. About 0.3 percent of active connections were affected, including 5,001 GitHub tokens; analyses of the disclosure additionally cite roughly 5,241 API keys from an auxiliary cache that was reachable during the breach window.
Group raids agencies in Russia and Belarus with likely AI-generated scripts (Leek Likho)
Kaspersky observed further targeted attacks by the group Leek Likho, also known as SkyCloak or Vortex Werewolf, on public sector organizations in Russia and Belarus from February to April 2026, in which an operator uses a covert Tor and SSH channel to bring in the tool rclone and exfiltrate files from USB drives. For each victim the group builds its own first stage with slightly altered file names, new readable variable names and some operations that change nothing. Kaspersky sees possible signs that a language model generates both the scripts and their names, and its conclusion states that Leek Likho uses AI to generate unique variants for each target.
North Korean group deploys a Rust backdoor with AI traces (HelloDoor, Kimsuky)
The North Korean group Kimsuky deploys HelloDoor, a backdoor in Rust, a language the group rarely uses according to Kaspersky. Kaspersky found emoji debug logs of the kind language models produce, alongside leftover typos such as decrytion failed that point to human post-editing; victims of the PebbleDash cluster include Brazilian and South Korean defense organizations and a German defense company.
AI agent attacks Brazilian financial institutions (SHADOW-AETHER-064)
A Portuguese-speaking group has been running agentic attacks on Brazilian financial institutions since April 2026; the agent operates through ProxyChains (a tool for routing through proxies) and SSH in the victim network, uses the tunneling tool Chisel plus Impacket and CrackMapExec (toolkits for attacks on Windows network protocols) and generates its scripts dynamically. The same Trend Micro report describes the sister cluster SHADOW-AETHER-040; Trend Micro found its six compromises of Mexican government entities through an exposed command server.
Suspected Chinese actor turns AI agents on a Japanese technology firm
Google’s Threat Intelligence Group (GTIG) analyzed a suspected PRC-nexus actor deploying agentic tools like Hexstrike (an open-source tool that bundles attack tools for AI agents) and Strix against a Japanese technology firm and a prominent East Asian cybersecurity platform. Hexstrike runs alongside the Graphiti memory system, a temporal knowledge graph that maintains a persistent state of the attack surface, so the agent decides for itself when to pivot between tools such as subfinder and httpx (which discover subdomains and probe web servers); in parallel the multi-agent penetration testing framework Strix automates identifying and validating vulnerabilities.
Malware against Ukraine with AI-written camouflage (CANFAIL, LONGSTREAM)
Google’s Threat Intelligence Group (GTIG) confirms that Russia-nexus attackers use the malware families CANFAIL and LONGSTREAM against Ukrainian organizations; both contain decoy code generated by a language model. In CANFAIL, comments left by the model explicitly mark certain code blocks as unused; GTIG believes the attackers likely asked the model for this padding to hide the malicious functionality. In the LONGSTREAM downloader, GTIG found 32 places that query whether daylight saving time is in effect, likely also generated code meant to look benign.
Vishing panel from the ShinyHunters orbit, one variant reworked with an LLM (Doko’s Panel)
Push Security gained access to Doko’s Panel and variants of it, which operators in the ShinyHunters and BlackFile orbit use to steer victims by phone to cloned sign-in pages for Okta, Microsoft, Google or crypto exchanges and to relay the password and one-time code by hand to the real service; submissions from real victims in the same week showed attacks in progress. A variant on the Okta phishing site Push first detected shows, by Push’s account, clear signs of having been reworked with a language model, such as verbose header comments titled NOTES FOR NEXT SESSION and duplicated server requests, which Push says is consistent with an operator pasting requirements into an LLM and accepting the output without understanding the existing code.
North Korean group builds npm decoy packages with AI (PromptMink, Famous Chollima)
Famous Chollima from North Korea has been publishing npm packages that ReversingLabs has tracked since October 2025; their sheer number and self-promoting README text, in ReversingLabs’ assessment, suggest the real targets might be AI coding agents looking for a fitting dependency. A harmless decoy package pulls in the payload, which scans directories for .env and .json files and for files with crypto-related names, exfiltrates source trees and plants SSH keys. On February 28, 2026, a commit co-authored by Claude Opus added the decoy dependency to a crypto trading agent; according to ReversingLabs, the packages themselves were built with generative AI, betrayed by a leftover question from the model asking whether it should also obfuscate the README a bit.
North Korean group lures Web3 developers using ChatGPT and Cursor (HexagonalRodent)
A North Korean group, tracked by Expel as HexagonalRodent, lures Web3 developers with fake job offers and coding tests that launch a backdoor when opened in Visual Studio Code. From its own telemetry, Expel documents the use of ChatGPT and Cursor (a programming environment with a built-in AI assistant), accidentally leaked prompts for two new tools and the building of at least one front-company website with the AI web designer Anima; the attackers’ database holds 26,584 wallets from 2,726 infected developer machines, and Expel found evidence that the attackers likely also had Western models check how conspicuous their own backdoors are.
Operator breaches over 900 companies with Claude Code and OpenClaw (Bissa Scanner)
An open server exposes a mass-exploitation operation in which Claude Code and OpenClaw (an open-source agent that works through tasks on its own) support the operator with troubleshooting, orchestration and refinement of the collection pipeline: React2Shell scanned against millions of targets, more than 900 companies compromised, more than 30,000 distinct .env files harvested. The operator triages the access and digs deeper only for targets in the financial, cryptocurrency and retail sectors.
NFC payment app with likely AI-written code steals PINs in Brazil (NGate)
Since around November 2025, attackers have been targeting Android users in Brazil with a tampered version of the legitimate app HandyPay, spread through a fake lottery website and a spoofed Google Play page; the app relays the payment card’s NFC data to a device under their control and sends the PIN to their command-and-control server. On that server, ESET found logs from four compromised devices in Brazil with captured PINs, IP addresses and timestamps. According to ESET, the attackers most probably used generative AI to write the injected code that exfiltrates the PIN, as indicated by emoji in its log output that are typical of AI-written text.
Intrusion attempt via Obsidian with an AI-generated RAT (PHANTOMPULSE)
Elastic Security Labs investigated an intrusion attempt in the REF6598 campaign, which approaches individuals in the financial and cryptocurrency sectors as a supposed venture capital firm over LinkedIn and Telegram and gives them access to a vault in the note-taking app Obsidian; once the victim enables plugin sync, trojanized plugins silently execute code. The chain culminates in the previously undocumented RAT PHANTOMPULSE, which Elastic calls heavily AI-generated, visible in abnormally verbose, step-numbered debug strings. In the observed intrusion, Elastic’s endpoint protection detected and blocked the chain at an early stage, before PHANTOMPULSE could execute.
Actor opens over 500 malicious pull requests with AI-generated payloads (prt-scan)
Across six waves and six accounts, an actor opens more than 500 malicious pull requests against GitHub repositories with misconfigured pull_request_target and moves from raw Bash scripts to AI-generated payloads adapted to each target’s tech stack; at least two npm packages of one maintainer are compromised; Wiz puts the success rate at under ten percent.
Backdoor with LLM hallmarks against Russian defense companies (WarpPlugin, GOFFEE)
According to PT ESC, the espionage group GOFFEE (Paper Werewolf) sends employees of Russian organizations archives with a questionnaire supposedly from a state-owned company; the Excel add-in (XLL) inside opens a decoy spreadsheet and, in the background, launches the WarpPlugin backdoor (also called EchoGather), which PT ESC describes as AI-generated. PT ESC has observed this activity since late 2025 and writes that GOFFEE uses AI agents to keep producing new lure files and WarpPlugin variants, and constantly generates new command server names as well. According to the Positive Technologies quarterly report, modules found in the group’s attacks on Russian defense companies show typical signs of LLM-generated code.
Phishing platform mines stolen Microsoft 365 mailboxes with AI (EvilTokens)
EvilTokens, sold as phishing-as-a-service since February 2026, abuses Microsoft’s device-code login (a method in which a code is confirmed on a second device) to capture access tokens for Microsoft 365 mailboxes. According to Sekoia, an AI pipeline reads up to 5,000 stolen emails, looks for payment threads worth exploiting and drafts matching fraud emails; in one incident Microsoft observed, an attacker used the AI feature to pick out compromised users in financial, executive or administrative roles. Microsoft’s investigators found that large portions of the platform itself were written with AI; the company counts more than 12,000 mailboxes taken over in over 10,000 organizations and had EvilTokens taken down with court authorization in September 2026, and London police arrested two suspects.
Malware with a likely AI-built obfuscation layer steals credentials (DeepLoad)
ReliaQuest investigated incidents in corporate networks in which users, lured by ClickFix (fake error messages that tell them to paste a command), launched the DeepLoad malware themselves: it hides its payload in the Windows lock screen process, steals credentials and reinfected a cleaned machine three days later through a WMI event subscription. ReliaQuest assesses with high confidence that AI built the obfuscation layer of thousands of meaningless variable assignments. In May 2026, Nigeria’s IT agency NITDA warned through its CERRT.NG of confirmed active targeting of Nigerian government agencies, financial institutions and businesses with DeepLoad.
Lone actor has Claude Code ship a backdoored BuddyBoss plugin
A French-speaking lone actor compromises the WordPress platform BuddyBoss and Caseproof’s license server and distributes a backdoored plugin version through the production infrastructure; 246 WordPress sites, more than 29 gigabytes of databases, about 150,000 user accounts and live Stripe keys are affected. From an open directory, Ctrl-Alt-Intel recovered the transcript of a Claude Code session in which the agent itself performs the Cloudflare bypass and the deployment of the tampered version after the actor staged a CTF scenario for it.
npm worm with a likely AI-written propagation script (CanisterWorm, TeamPCP)
On March 20, 2026, Aikido detected a previously unseen worm that used stolen npm tokens to compromise packages, 28 in the @emilgroup scope and 16 under @opengov by the time of its report, and fetched the address of its payload from a canister (a program on the decentralized blockchain platform Internet Computer, used here as a dead drop); at the time of the report, the canister still pointed to a YouTube video rather than malware. Aikido believes the worm is the work of TeamPCP and says its propagation script, deploy.js, appears to be entirely vibecoded, that is, written with AI. About an hour after the first wave, the operator reworked the worm to search infected machines for npm tokens and use them to spread on its own.
Fake game mods install crypto miners via a likely AI-written script (WinUpdateHelper)
According to McAfee Labs, more than 440 ZIP archives disguised as game mods, cheats, drivers and AI tools, hosted on Discord, SourceForge and other sites, install crypto miners or further payloads such as SalatStealer and Mesh Agent on computers mainly in the United States, the United Kingdom and India; seven traceable Bitcoin wallets received about $11,500. The infection is carried out by a PowerShell script that the malicious WinUpdateHelper.dll fetches from the command-and-control server and runs in memory. Explanatory comments and structured sections in it strongly indicate a language model, McAfee says; one of them refers to your GitHub URL, meaning the attackers’ repository.
Hijacked Ukrainian websites serve iOS exploits with LLM traces (DarkSword, UNC6353)
According to Lookout, the likely Russian group UNC6353 used hidden iframes on two compromised Ukrainian websites, a news site from the Donbas and the site of the Seventh Administrative Court of Appeal, to serve the DarkSword exploit chain to visitors running iOS 18.4 through 18.6.2. Written in JavaScript, the chain gains kernel read and write access, sends passwords, messages, photos and crypto wallet data to a command server within minutes and then cleans up after itself. Lookout says patterns in the code suggest that at least some of the implant was created with language models, and it also sees indicators of an LLM in the code of the server that receives the stolen data.
Interlock group uses a likely AI-written C2 client (Slopoly, Hive0163)
IBM X-Force finds the PowerShell C2 client Slopoly in the arsenal of Hive0163, which deploys Interlock ransomware; the client maintained access to a victim server for more than a week and, in the investigators’ assessment, was likely written by a language model.
Iranian cluster uses a likely AI-written wiper against Stryker (Void Manticore)
In its destructive wave against Israel and US targets such as the medical technology company Stryker, the Iranian cluster Void Manticore, also known as Handala, distributes a PowerShell wiper via group policy alongside the Handala wiper; based on code structure and detailed comments, Check Point considers the PowerShell wiper likely developed with AI assistance.
Phishing in Algeria, Kuwait and Mongolia, a Turkish malware prompt in related files
According to PT ESC, in late February and early March 2026 an attacker sent archives to organizations in Algeria, Kuwait and Mongolia, disguised as messages from energy companies, government bodies and the military; an LNK shortcut inside fetched scripts that used the Rclone sync tool to upload Telegram data and desktop documents to the attacker’s account on the Mega cloud storage service. Among related files PT ESC found loaders for the XMRig cryptominer and comments in Turkish, and it also found a Turkish prompt the attacker used to have a language model write malware, casting the model as an uninhibited, flirtatious female hacker. Over 81 days the miners earned about 436 rubles on infected machines.
Actor has a language model sift hundreds of Salesforce environments for loot (GRUB1)
In Cloudflare’s first own threat report, Cloudforce One describes how the actor GRUB1, after capturing OAuth access through the Salesloft Drift integration, used a language model to identify the data tables with the most valuable contents in hundreds of third-party Salesforce environments shortly before accessing the production instances. Cloudflare itself was among those affected in August 2025.
Backdoors with AI traces targeting Iraqi government officials (Dust Specter)
In January 2026 Zscaler ThreatLabz observed attackers posing as Iraq’s Ministry of Foreign Affairs to target Iraqi government officials with the previously unknown backdoors TWINTALK and GHOSTFORM; one archive containing GHOSTFORM was hosted on the compromised government website ca.iq. Zscaler infers that generative AI was used in developing the malware from emojis in the code and from a seed value in a checksum function that appears to be a placeholder commonly found in AI-generated code. Zscaler links the actor, which it tracks internally as Dust Specter, to Iran.
Self-described Claude agent attacks GitHub workflows and hijacks Trivy (hackerbot-claw)
A GitHub account describing itself as an autonomous security agent powered by Claude Opus 4.5 attacks CI/CD workflows at Microsoft, Datadog, CNCF, RustPython and Aqua Security between February 21 and March 2, 2026 and achieves code execution in at least six of seven targets according to StepSecurity; Pillar counts six targets and five successes for the same incident; at Datadog, both attempts, including a prompt injection against the AI-assisted issue triage, came to nothing. At aquasecurity/trivy the account exfiltrates a GitHub token with write permissions, deletes 97 releases by Pillar’s count, makes the repository private and pushes a trojanized extension of Trivy (a widely used vulnerability scanner for containers and projects) to OpenVSX (an open marketplace for editor extensions); Pillar rates the operation as human-strategic and LLM-tactical, eleven seconds from fork to push.
Hacktivists hit Russian agencies and companies with AI-generated scripts (Forbidden Hyena)
On the command server of the hacktivist cluster Forbidden Hyena, BI.ZONE found obviously AI-generated scripts, two PowerShell scripts for persistence and AnyDesk and a Bash script that loads an implant of the open-source C2 framework Sliver, with debug strings, detailed comments and readable variable names without obfuscation. The goal is to deploy the BlackReaperRAT backdoor, followed by encryption with the Milkyway ransomware; the victims are Russian government agencies and companies in healthcare, energy, engineering, retail and utilities.
One operator steers Claude Code and GPT-4.1 against nine Mexican government agencies
From three rented servers, Gambit Security reconstructs the work of a single operator against nine Mexican government agencies between late December 2025 and mid-February 2026: Claude Code generates and executes about 75 percent of all commands run on the servers, 1,088 prompts yield 5,317 commands, and in parallel GPT-4.1 turns 305 servers into 2,597 intelligence reports. Dragos describes Claude independently identifying a SCADA interface at the Monterrey water utility as a target and steering an unsuccessful password spray; Trend Micro, CloudSEK, Unit 42 and Oasis Security describe the same complex from their own findings, linked by shared infrastructure addresses.
Low-skilled actor takes over 600 FortiGate devices with DeepSeek and Claude Code
According to Amazon, an actor of low to medium capability compromises more than 600 FortiGate devices in more than 55 countries between January 11 and February 18, 2026, not through a vulnerability but through exposed management interfaces with weak single-factor credentials. At least two commercial language models supply his attack plans, reconnaissance tools and lateral movement strategies; whenever he tries more than the most straightforward automated paths, he largely fails. A second analysis of the same infrastructure shows DeepSeek as planner, a custom MCP server named ARXON and a settings file that lets Claude Code run tools such as Impacket (a toolkit for attacks on Windows network protocols) and Metasploit (a widely used attack tool with ready-made exploits) without asking for approval.
Iranian group uses a backdoor with AI traces in the Middle East (Olalampo, MuddyWater)
In the Rust backdoor CHAR of the Iranian group MuddyWater, Group-IB found debug strings with emojis, an artifact rarely seen in human-authored code, plus a decoy website on the command server that Group-IB rates as highly likely AI-generated; targets are government, telecommunications, energy and critical infrastructure in the Middle East and North Africa. Unit 42 independently analyzed the same program as LampoRAT, disguised as a Kaspersky process, against a marine and energy company in the Middle East, and characterizes the group’s AI use as an emerging, not yet standardized practice. Two weeks later, Ctrl-Alt-Intel recovered the same actor’s command server components from one of his servers and likewise found emojis in the output of his self-built command server KeyC2, emojis it reads as a sign of AI-assisted development.
Actor uses Gemini to scout accounts, then targets them with phishing (UNC6418)
Google’s Threat Intelligence Group (GTIG) observed the unattributed actor UNC6418 misusing Gemini for targeted intelligence gathering, specifically seeking out sensitive account credentials and email addresses. Shortly after, the actor targeted all these accounts in a phishing campaign focused on Ukraine and the defense sector. Google disabled the assets associated with this activity.
Likely AI-generated script exploits React2Shell and mines Monero on 91 hosts
Darktrace finds a Python tool in its CloudyPots honeypot network, placed by an attacker through a Docker daemon deliberately left internet-facing without authentication. The script picks targets itself, exploits the React2Shell vulnerability CVE-2025-55182 and installs the Monero miner XMRig; the mining pool statistics show 91 workers, meaning 91 infected hosts. Darktrace considers the script fully AI generated, pointing to a comment density untypical for malware, to the opening comment Educational/Research Purpose Only, and to a test with GPTZero (a tool meant to detect machine-generated text).
Linux framework hits tech companies, version 2.0 written with TRAE SOLO (VoidLink)
According to Cisco Talos, the Linux framework VoidLink has hit multiple victims since September 2025, mostly in the technology sector, along with financial services firms; the actor UAT-9921 breaks into servers with previously obtained credentials or through Java deserialization flaws and installs VoidLink there. Check Point Research had earlier reconstructed from materials on an openly reachable server that a single person had the framework written almost entirely by TRAE SOLO, the AI assistant in the TRAE development environment, starting in late November 2025, and had more than 88,000 lines of working code after one week; Elastic also found traces of a language model in the source of the rootkit components. In the intrusions themselves, UAT-9921 does not appear to use AI tools, according to Talos.
Attacker becomes AWS admin in eight minutes with likely AI-written code
An attacker enters an AWS environment with credentials from publicly accessible S3 buckets, injects code into a Lambda function (the AWS service that runs stored code on demand) with an administrator role and moves through 19 identities, reaching admin rights eight minutes after initial access, before abusing the victim’s models in Amazon Bedrock (the AWS service for accessing language models). A script he uploads to the victim’s account is meant to clone an Anthropic repository called training-scripts from GitHub, which does not exist. According to Sysdig, this suggests the code came from a language model that had hallucinated the name.
Partly AI-written wiper hits a manufacturer during a wave of attacks in Poland (LazyWiper)
On December 29, 2025, an attacker strikes more than 30 wind and solar farms in Poland in a coordinated operation, destroys remote terminal units and controllers at the grid connection points and thereby cuts the link to the distribution system operator; a combined heat and power plant and a manufacturing company are hit in parallel; according to CERT Polska and CISA, electricity production continued and the heat supply was not interrupted, and the attack on the manufacturer was opportunistic. LazyWiper, a PowerShell script with one function that CERT Polska assesses as written by a language model, runs at the manufacturer; because the script is largely machine-generated, CERT Polska considers it useless for attribution, while the infrastructure overlaps with the Static Tundra cluster.
Implant with LLM traces likely targets NGOs documenting Iran’s protests (SloppyMIO)
The campaign likely targets NGOs and individuals documenting human rights violations during the Iranian protests. The C# implant exfiltrates files, loads modules, hides its configuration in images and uses GitHub gists, Google Drive and the Telegram bot API; several LLM artifacts were left unsanitized, including a comment touting the stager as ULTRA-RELIABLE & STEALTHY VBSCRIPT STAGER (Final Production Version).
Suspected Vietnamese actor sends fake job offers with likely AI-written loaders (PureRAT)
An actor Symantec places in Vietnam sends phishing emails posing as job offers; archives on Dropbox use DLL sideloading to load batch and Python scripts that install PureRAT or an HVNC tool (remote access through a hidden second desktop). Symantec considers it very likely that AI wrote several of these scripts: nearly every step carries a detailed Vietnamese comment, some comments include emojis, and one Python loader still contains the note to paste the HVNC shellcode here.
Pakistan-based group has language models build new implants daily against India (APT36)
The Pakistan-based group APT36 uses language models to produce new throwaway implants in Nim, Zig and Crystal every day for use against the Indian government and diplomatic missions; metadata from AI-integrated code editors and Unicode emojis in the binaries point to machine generation. Bitdefender describes the pattern as an attempt to overwhelm detection with sheer volume, but calls the samples themselves generic, inconsistent and error-prone; one stealer could never exfiltrate data because of a placeholder instead of the C2 address. Zscaler had already documented two of these implants, the backdoors SheetCreep and MailCreep, in January 2026 and read the emojis in SheetCreep’s error handling as a strong sign of AI-assisted development.
North Korean group targets blockchain developers with malware showing AI traces (KONNI)
The North Korean group KONNI targets developer and engineering teams with blockchain ties; VirusTotal submissions from Japan, Australia and India point to an expansion beyond South Korea. The chain runs from a ZIP with decoy PDF and LNK through a PowerShell loader and a backdoor with UAC bypass and disguised OneDrive persistence to SimpleHelp remote access; the AI indicator, besides the verbose header documentation, is a leftover placeholder comment for the project UUID.
Likely AI-written script goes after Veeam credentials at a nonprofit
At a nonprofit, an attacker enumerated the network, moved laterally over WinRM and then tried to run a PowerShell script that Huntress classifies as AI-generated: it was meant to read and decrypt the credentials stored in the database of the Veeam backup software. The script failed to run, and defenders shut the attack down.
2025
Agent model ROME opens a reverse SSH tunnel in training and mines on GPUs
During training of the agent model ROME, Alibaba Cloud’s managed firewall flags security policy violations coming from the team’s own training servers: attempts to probe or access internal network resources, and traffic patterns consistent with cryptomining-related activity. The team first takes this for a misconfiguration or an outside compromise, but the violations recur across multiple runs, and correlating the firewall timestamps with the team’s own system telemetry and reinforcement learning traces shows that the traffic coincides every time with episodes in which the agent invokes tools and executes code. In the most striking instance it establishes and uses a reverse SSH tunnel from an Alibaba Cloud instance to an external IP address, an outbound-initiated remote access channel that, the paper says, can neutralize ingress filtering and erode supervisory control; alongside that the team observes it repurposing provisioned GPU capacity for mining without authorization, diverting compute away from training. Both lie outside the bounds of the intended sandbox, no task prompt had asked for them, and the paper calls them instrumental side effects of autonomous tool use under reinforcement learning optimization.
Student allegedly used ChatGPT to steal 7.25 million records from Japan’s Kaikatsu CLUB
Between January 18 and 20, 2025, a student steals about 7.25 million member records of the Japanese internet cafe chain Kaikatsu CLUB and comments on the attacks live on Discord. According to Tokyo police, he wrote the scraping program himself, improved it with ChatGPT and asked the model how to get past the target system’s defenses and how to respond to error messages; in December 2025 the 17-year-old was re-arrested.
South Korean VPN site serves a likely AI-written backdoor (NKNShell)
According to AhnLab ASEC, a South Korean VPN provider’s website hosted a tampered archive in November 2025 that, alongside the genuine VPN client, used several PowerShell scripts to install the previously unknown NKNShell backdoor and two other remote access tools that let the operator control the machine. ASEC suspects that NKNShell and the scripts were written with generative AI. It attributes the attack to Larva-24010, an actor that has targeted South Korean VPN providers since at least 2023.
Claude Code runs most of a China-attributed campaign (GTG-1002)
Claude Code runs as an orchestrator with subagents via MCP against about 30 targets in technology, finance, chemicals and government and carries out 80 to 90 percent of the campaign itself; humans intervene at only four to six decision points. The jailbreak comes from role-playing as a contracted pentest firm and breaking the work into innocuous-looking subtasks; Anthropic attributes the actor to China with high confidence and concedes that Claude occasionally hallucinated credentials or presented publicly available information as secret.
Attacker drains Balancer V2 pools with a smart contract believed to be partly AI-written
On November 3, 2025, an attacker drained Balancer V2 pools on several blockchains and, according to Halborn, stole more than $120 million; projects built on top of Balancer also lost funds. Halborn believes the attack’s smart contract was partly vibe-coded, that is, copied from a language model. It contained console.log statements of the kind AI models often add; developers usually remove them before deployment because they are meant for debugging and cost transaction fees.
North Korean group hits crypto firms with an AI-assisted stealer (GhostCall, BlueNoroff)
The North Korean group BlueNoroff runs the GhostCall and GhostHire campaigns against Web3 and crypto companies in India, Turkey, Australia and other countries, GhostCall since at least mid-2023. As AI evidence, Kaspersky cites comments with check-mark emojis in the SilentSiphon stealer, and the profile pictures of supposed participants in fake Zoom calls carry C2PA metadata (provenance data that image tools write into the file), and that metadata points to editing with GPT-4o.
Phishing against Beazley Security via a likely AI-built panel (Quantum Redirector)
A phishing email sent to Beazley Security, which employees reported to the company’s security team, led through a Quantum Redirector, a redirect panel that sends bots and researchers to harmless sites and real people through an obfuscated intermediate page to a phishing kit. Beazley Security Labs considers the panel and the obfuscation likely AI-generated, partly because of the name Quantum and individual coding errors. Beazley found several hundred more Quantum Redirectors whose landing pages almost all imitated email services, and it is working with law enforcement to take the redirectors down.
Partly AI-written banking trojan spreads via WhatsApp in Brazil (Maverick)
A mass campaign in Brazil distributes the new banking trojan Maverick over WhatsApp; on infected computers it hijacks the victim’s messenger account, sends itself on to the contacts and is designed to capture credentials on the websites of 26 Brazilian banks. Kaspersky blocked 62,000 infection attempts in the first ten days of October alone and writes that Maverick has infected many people in Brazil. According to Kaspersky, the code was written with AI, especially the routine that decrypts the certificate for the command-and-control channel; Trend Micro, which tracks the campaign as Water Saci, found circumstantial evidence in December 2025 that the attackers had a language model port their spreading script from PowerShell to Python.
China-linked group uses ChatGPT for spear phishing in five languages (GOVERSHELL, UTA0388)
A China-aligned group uses language models to generate multilingual spear-phishing campaigns in English, Mandarin, Japanese, French and German, complete with invented sender organizations, and develops the GOVERSHELL backdoor in five variants; Volexity customers in North America, Asia and Europe are affected. Volexity concluded independently from its own evidence that the group used AI; a day before Volexity published, OpenAI had confirmed in its own report that the group used ChatGPT.
Likely AI-generated stealer hits Ukrainian authorities (WRECKSTEEL, UAC-0219)
In March 2025, CERT-UA documented attacks on Ukrainian government bodies and critical infrastructure with a PowerShell stealer that exfiltrated documents and screenshots. In its half-year report of October 2025, Ukraine’s State Service of Special Communications and Information Protection (SSSCIP), which CERT-UA belongs to, writes that there are grounds to believe WRECKSTEEL’s PowerShell scripts were generated with AI. More generally, it says several malware samples it investigated show clear signs of AI generation and it expects attackers to expand their use of AI.
Likely AI-obfuscated SVG attachment in phishing emails to US organizations
On August 18, 2025, a phishing campaign that Microsoft describes as limited, sent from the compromised email account of a small business, delivered an SVG attachment disguised as a PDF, meant to steal credentials, mainly to US organizations; Microsoft Defender for Office 365 detected and blocked it. The file hides its function in a sequence of business terms that embedded JavaScript turns back into code, which redirects the browser to the phishing page. Microsoft’s AI tool Security Copilot judged the code highly likely synthetic and likely generated by a language model.
Worm with a likely LLM-generated payload compromises hundreds of npm packages (Shai-Hulud)
Wiz calls Shai-Hulud the first successful self-propagating attack in the npm ecosystem; the worm compromises hundreds of packages, including @ctrl/tinycolor with millions of weekly downloads. On September 17, Wiz notes that one of the payloads looks machine-generated while a second variant does not share the pattern; based on comments and emojis, Unit 42 assesses the Bash script as LLM-generated with moderate confidence. Wiz considers the campaign a direct follow-on of the s1ngularity/Nx compromise in late August 2025, through which GitHub tokens and then npm tokens were stolen.
Likely AI-written loaders infect hotel front desks (RevengeHotels, TA558)
RevengeHotels attacks hotel front desks, in the 2025 campaign with a focus on Brazil and Spanish-language lures; among earlier Spanish-speaking victims Kaspersky names Argentina, Bolivia, Chile, Costa Rica, Mexico and Spain, and older reports also named Russia, Belarus and Turkey, though the current campaign shows no activity there. Kaspersky considers the JavaScript loaders and PowerShell downloaders machine-generated: comments on almost every action, leftover placeholders, no obfuscation at all; the payload is VenomRAT.
Attacker installs security software on their own machine and exposes their AI use
On July 9, 2025, an attacker installs a Huntress trial on his own working machine and thereby exposes his browser history from May 29 to July 9: an automation platform with Telegram bots for phishing workflows, searches for free AI services without sign-up, the use of several text generators to process data, and searches for other people’s instances of Evilginx (a tool that mirrors login pages and captures session cookies). Huntress links the infrastructure to more than 2,471 identities accessed in two weeks.
Lone criminal extorts at least 17 organizations with Claude Code (GTG-2002)
A lone criminal extorts at least 17 organizations in healthcare, emergency services, government and religious institutions. Claude Code handles reconnaissance, credential harvesting and network intrusion, chooses which data to exfiltrate, calculates the ransom from the stolen financial data and writes the extortion note to hit each victim’s specific pressure points; instead of encrypting, he threatens publication, with demands sometimes exceeding 500,000 dollars.
Suspected Chinese actor attacks Vietnamese telecom companies with Claude
Anthropic describes an actor whose tradecraft, language and targeting are consistent with Chinese APT operations and who used Claude as an advisor and code developer in 12 of 14 MITRE ATT&CK tactics during a nine-month campaign against critical infrastructure in Vietnam. With Claude, the actor built WordPress exploitation frameworks and privilege escalation exploits for Linux kernel vulnerabilities, among other things. According to Anthropic, the actor appears to have compromised major Vietnamese telecommunications providers, government databases and agricultural management systems.
Likely AI-written apps smuggle in a backdoor (JustAskJacky, TamperedChef)
G DATA describes free programs that do what they promise while carrying a backdoor, offered on professional-looking websites: the JustAskJacky advice app, which launches itself several times a day through a scheduled task and runs commands from its command server, and a recipe app called TamperedChef, which executes commands hidden in the spaces and tabs of its recipes. For TamperedChef, G DATA sees strong indicators that a language model wrote the code, which is neatly structured and thoroughly commented, down to comments that reveal the use of steganography. Trend Micro tracks both apps as EvilAI, says JustAskJacky’s code was also produced with AI and, in the week starting August 29, 2025, logged the most detections in India, the US and France.
npm package drains crypto wallets, code likely written by Claude (@kodane/patch-manager)
Safety found a wallet drainer in the npm package @kodane/patch-manager, which posed as a cache manager for the npm registry; after installation it sets itself up as a persistent background process and transfers the balance of any Solana wallets it finds to a hardcoded address. Starting July 28, 2025, the author published 19 versions within two days; before npm blocked the package on July 30, it was downloaded more than 1,500 times, and on the openly accessible command-and-control server Safety saw two compromised machines. According to Safety, the package appears to have been written by Claude, judging among other things by emojis in the source code, verbose comments and the name suffix Enhanced.
Likely AI-assisted malware hides a rootkit in panda images (Koske)
Koske enters through a misconfigured instance of JupyterLab (a notebook environment for Python) and delivers two panda pictures as polyglot JPEGs (files that are a valid image and executable code at once) from which two things emerge: an in-memory-compiled rootkit and a shell script that persists through cron and systemd, overwrites the DNS settings and flushes the iptables rules. The miners support 18 cryptocurrencies with hardware-dependent selection. Aqua sees clear signs of AI-assisted development in the verbose comments, modularity and adaptability.
Malware gets its commands from Qwen2.5-Coder at runtime (LAMEHUG, APT28)
CERT-UA reports malware against Ukraine’s security and defense sector that queries a language model at runtime, Qwen2.5-Coder-32B via the Hugging Face API, to generate Windows commands for reconnaissance and document theft from text descriptions and execute them immediately. The malware calls the model itself instead of hard-coding commands.
AI chatbots help affiliates negotiate with victims (GLOBAL GROUP)
GLOBAL GROUP, launched on June 2, 2025 by the actor behind Mamona, lists 17 victims in the US, UK, Australia and Brazil from healthcare, industry and services within six weeks. Its negotiation portal uses AI chatbots so that non-English-speaking affiliates can handle victims themselves; EclecticIQ reviewed a transcript demanding one million dollars, about 9.5 bitcoin, within 48 hours.
Fake gaming app spreads malware developed with ChatGPT (ScopeCreep)
According to OpenAI, an apparently Russian-speaking actor used ChatGPT to develop multi-stage Windows malware in Go step by step and got help setting up its command-and-control server. ScopeCreep was distributed through a public repository posing as Crosshair-X, a popular program that overlays a custom crosshair in video games; anyone who ran the fake pulled further malicious files from the attacker’s infrastructure, designed to steal browser-stored credentials, tokens and cookies. OpenAI banned the accounts, and the code hosting provider took the fake down.
Attacker uploads a likely AI-generated miner script through an unprotected Open WebUI
At a Sysdig customer, a training system running Open WebUI (a web interface for running language models) sits on the internet without authentication and with administrator privileges. Through it, the attacker uploads a Python script obfuscated 64 layers deep that fetches the crypto miners T-Rex and XMRig; a detection tool rates the payload as 85 to 90 percent likely AI-generated or heavily AI-assisted.
Chinese student harasses fellow students by text message with an AI-written program
According to the cybersecurity bureau of China’s Ministry of Public Security, a student surnamed Hu broke into a system at his university and obtained more than 20,000 student records. Through a vulnerability he had previously found in a mini program (an app that runs inside a larger app), he used AI-written software to register accounts in bulk with the stolen phone numbers and replaced the SMS verification codes with obscene content that went to the students. Hu has confessed to illegally obtaining data from computer systems.
Actor builds stealers, C2 servers and phishing pages with ChatGPT (EncryptHub, LARVA-208)
A misconfigured directory on EncryptHub’s command server exposed configuration files and the Telegram bot, and in the end Outpost24 had the attacker’s own ChatGPT conversations: with them he builds clippers (malware that swaps copied wallet addresses in the clipboard) and cookie stealers, Telegram bots, C2 servers, phishing pages, mail servers and onion services, has negotiations translated and the forum ads written with which he put two exploits up for sale on March 11, 2025. Prodaft counts at least 618 compromised organizations for the same group since June 2024.
Operator has ChatGPT write a fake letter mid-intrusion (Black Basta)
In the leaked internal chats of the ransomware group Black Basta, GuidePoint Security finds an example from February 21, 2024: the operator nn recounts that the person at the machine noticed something was wrong when the operator took over the computer, and that this person started to panic, so the operator quickly had ChatGPT write a plausible fake letter, one that passes the access off as an examination of the domain controller by a technical specialist. GuidePoint considers it likely that this let the actor show a properly written message to whoever discovered the intrusion, and possible that it calmed that person’s first reaction and let the intrusion continue.
Ransomware group destroys data with a likely LLM-generated PowerShell script (APT INC)
According to CrowdStrike, the big game hunting ransomware group APT INC used an uncommon, destructive PowerShell script to destroy data on a physical host. Based on the comment formatting, the similarity to output from other LLMs and the lack of public sources resembling the script, CrowdStrike considers it likely that a language model generated the code.
Teenagers hijack Rakuten accounts with a ChatGPT-assisted program to get mobile lines
Tokyo police arrested three students aged 14 to 16 who allegedly used a self-written program and purchased credentials to log in to Rakuten Mobile automatically and sign up for mobile lines; they are accused of taking out 105 lines through eleven other people’s accounts between May and August 2024. According to the Yomiuri newspaper, they used ChatGPT while writing the program to work more efficiently and speed up processing. One of the students told investigators he had signed up for more than 1,000 lines since December 2023; the lines were resold over Telegram, and police put the proceeds at about 7.5 million yen in cryptocurrency.
Jamtara police arrest a gang that built Android malware with ChatGPT (DK Boss)
Jamtara’s cyber police arrest six men of a syndicate that, under the name DK Boss, builds malicious Android packages posing as applications for government welfare schemes and as banking apps, redirects SMS and calls to a central panel and sells the packages to other gangs for 20,000 to 25,000 rupees. Data of about 2,700 victims with more than 270,000 intercepted messages was recovered; point 13 of the press release states the group used ChatGPT to develop the malware.
Likely AI-made HTML files smuggle in a RAT (XWorm)
In the third quarter of 2024, HP Sure Click stopped a campaign that delivered the XWorm remote access trojan through HTML smuggling (the malware is hidden, encoded, inside the HTML file itself): opened in a browser, the file downloads an executable in the background that looks like a shortcut in File Explorer but is actually a compiled AutoIt script, which loads XWorm into memory only when the user starts it manually. According to HP, the HTML files bear hallmarks of being written with generative AI, namely comments on even simple statements and a page design almost identical to what ChatGPT 4o produced when asked for a download page.
Ransomware group claims over 85 victims and writes its code with AI help (FunkSec)
In December 2024, FunkSec publishes more than 85 claimed victims, more than any other ransomware group that month. The public scripts of an inexperienced Algerian author carry detailed comments in perfect English that Check Point considers LLM-generated, and the Rust encryptor shows similar patterns; in its own published messages, the group itself links the development of its ransomware to AI assistants.
2024
TradingView lure script built from ChatGPT drafts leads to NetSupport RAT
According to Gen, unsuspecting users copied a malicious script from legitimate content-sharing sites that urged them to enable dev-mode for TradingView and to run terminal commands that ultimately install malware; the attack chain leads to NetSupport RAT. Through the clipboard protection in Norton, Avast and AVG, Gen traced the script’s development in three stages: the first two versions were clearly drafts obtained from ChatGPT, which the attackers then refined into the final version.
Eight possible AI agents among eight million hits on an SSH honeypot
Reworr and Dmitrii Volkov of Palisade Research run an SSH honeypot on the open internet whose login banner, command output and system files carry prompt injections. Anyone acting on the injected instruction counts as a potential AI agent; whether a model was really answering, the authors check separately through response time, since their own test agents usually replied within 1.7 seconds. Over about three months they log 8,130,731 interaction attempts, among them eight potential AI agents.
Spear phishing targets OpenAI employees, ChatGPT used for recon (SugarGh0st, SweetSpecter)
In May 2024 OpenAI received a tip from a credible source that the suspected China-based actor SweetSpecter was sending spear phishing mails to the corporate and personal addresses of individual employees: the sender posed as a ChatGPT user asking for support, and an attachment named some problems.zip held a shortcut file that, when opened, displays a document listing apparent ChatGPT error and service messages while decrypting and running the SugarGh0st remote access trojan in the background; according to OpenAI the mails never reached the corporate mailboxes and the attack failed. ChatGPT accounts running on the same infrastructure were used for reconnaissance, vulnerability research and scripting, among other things on vulnerable Log4j versions and on uploading a web shell with sqlmap (a tool that exploits SQL injection automatically).
Likely AI-written scripts in a fake invoice deliver AsyncRAT
In early June 2024, HP Sure Click isolated an HTML attachment disguised as an invoice in a French-language email; the file releases an AES-encrypted archive only after a password is entered. A VBScript inside starts a chain of JavaScript and PowerShell that ends with the AsyncRAT remote access trojan running. Because the VBScript and JavaScript are unobfuscated and commented line by line, and their structure and function and variable names fit the same pattern, HP considers it highly likely that the attacker wrote them with the help of generative AI.
Attackers inject likely AI-generated malicious code into WordPress.org plugins
In June 2024, using five WordPress.org developer accounts whose passwords came from unrelated data breaches, attackers pushed malicious code into plugins such as Social Warfare and Blaze Widget; on sites that installed the update the code created an administrator account and sent its credentials to an attacker server, and later versions loaded a cryptominer and a wallet drainer. According to Wordfence, non-functional or poorly refactored code and a lack of code reuse suggest that AI generated parts of the code. In April 2025 Wordfence wrote that the malware from this attack was AI-generated.
Phishing campaigns load malware through likely LLM-written scripts
Symantec observed phishing campaigns whose scripts for downloading malware were, by the vendor’s analysis, apparently generated with language models. In a campaign targeting a wide range of sectors, an LNK file from a password-protected ZIP attachment runs a PowerShell script likely generated by an LLM; the final payloads deployed included the Rhadamanthys stealer and the CleanUpLoader backdoor. In a second chain, disguised as an HR notification, an HTML file with JavaScript highly likely generated by an LLM downloads a loader for Dunihi (H-Worm).
Likely LLM-written loader targets German organizations (TA547)
In March 2024, the initial access broker TA547 delivers a PowerShell loader script for the Rhadamanthys stealer to dozens of German organizations via LNK, disguised as a Metro invoice. Proofpoint considers the grammatically perfect, hyper-specific line comments typical LLM output; it is the first campaign in which researchers observed TA547 use Rhadamanthys.
Likely LLM-written commands dump Entra ID identifiers (Scattered Spider)
CrowdStrike describes how Scattered Spider, in the second half of 2023, used the Azure AD PowerShell module at a North American financial services victim to download all users’ immutable Entra ID identifiers; through an Entra ID backdoor the actor could then log in as any of them. CrowdStrike says the PowerShell used resembled large language model output such as that from ChatGPT, and that the pattern of one comment, the actual command and then a new line for each command matches the Llama 2 70B model output.
Attacker opens ChatGPT while stealing Azure credentials (Indrik Spider)
CrowdStrike Services responded to an incident in February 2023 involving Indrik Spider and Bitwise Spider’s LockBit RED ransomware, during which Indrik Spider exfiltrated credentials from the cloud-based credential manager Azure Key Vault. Logs show the attacker visiting ChatGPT while working in the Azure portal, presumably to understand how to navigate in Azure, and using search engines such as Google and Bing as well as GitHub to work out how to exfiltrate the Key Vault credentials. CrowdStrike reads the search engines and the ChatGPT visits as a sign that the group is likely new to the cloud and is using generative AI to fill those knowledge gaps.
Five nation-state actors from Russia, North Korea, Iran and China use GPT-4 for groundwork
Microsoft and OpenAI document for the first time five state actors from Russia, North Korea, Iran and China using GPT-4: four for reconnaissance on targets or technology, all five for scripting, three of them additionally for phishing texts, two also for translation. What is documented is groundwork throughout, such as research on satellite and radar technology, no attack against a target; Microsoft notes that it has not observed any particularly novel AI-enabled attack techniques.
2023
Four suspects refine ransomware with ChatGPT to extort a Hangzhou firm
A company in Hangzhou reports encrypted servers on November 20, 2023, and the attackers demand 20,000 Tether (a dollar-pegged cryptocurrency). Police arrest four suspects with security qualifications and experience at large internet companies, who confess to writing the malware themselves, optimizing it with ChatGPT, scanning for vulnerabilities and extorting; the South China Morning Post calls it the first such case in China.
Suspect empties company accounts with a draining program written by ChatGPT
On August 24, 2023, Zhejiang’s provincial police present five typical cases from their crackdown on cybercrime, and the first is the earliest entry in this list: in April 2023, Hangzhou’s cyber police notice corporate payment accounts behaving oddly. The suspect, arrested in Thailand, obtained the payment keys through a system flaw, then used ChatGPT to write a withdrawal program, emptied the accounts in series and laundered the proceeds through cryptocurrencies; police credit the intrusion to his skill and the tool to the model.
Context
The list is sorted by the day a case became public. The attack itself often lies well before that. Black Basta, EncryptHub, BlueNoroff and BREEZE COMET can be dated to 2023 and 2024, but they came to light months to years later. Black Basta and EncryptHub surfaced only through the attackers’ own slips: leaked internal chats in one case, an open directory holding the actor’s own ChatGPT conversations in the other. Sorted by the time of the attack rather than by disclosure, the list would be more densely populated in its early phase.
Attackers began using AI long before there were agents. In February 2023, an attacker opened ChatGPT in the middle of an intrusion; in CrowdStrike’s reading, he wanted to find his way around the Azure portal. In April 2023, police in Hangzhou noticed corporate payment accounts behaving oddly; by their account, the offender had ChatGPT write the program with which he turned stolen payment keys into money in bulk. From the second half of 2023, researchers came across malicious code they considered LLM-generated, at first only because of the style of its comments. In 2025 came AI-written lures and a negotiation portal with chatbots. In July 2025, malware called a model at runtime on its own, the first case of its kind in the list, and in November Anthropic reported that an agent had handled 80 to 90 percent of an espionage campaign by itself. Since spring 2026, AI has turned up in cases of every size, with opportunists as well as state actors, and since the summer, agent-run attacks with hundreds of victims have been piling up.
So far this list contains no attack that disrupted a physical process and had a documented AI component. According to CISA and four other US agencies, however, attackers have already gained access to industrial equipment. Their August 2026 advisory says the attackers used AI-generated scripts to read and write data blocks on internet-exposed Siemens S7 controllers in the US. The agencies assess this as likely reconnaissance in preparation for later disruption; they name neither victims nor an actor, and do not say how they determined that the scripts were AI-generated. In the Polish sabotage case of December 2025, CERT Polska’s AI assessment concerns only a wiper script, and that script was found at a manufacturing company hit incidentally. For the destroyed remote terminal units at the wind and solar farms, the report names no AI involvement. In the attack on Mexican government agencies, Dragos describes Claude independently identifying a SCADA interface at the Monterrey water utility as a target, but its password spray did not get it into the OT environment.
What has shifted is mainly the attackers’ cost-benefit calculation. According to OALABS, a technically weak actor compromised at least 14 companies with a stolen Claude instance, and according to Unit 42 agents replaced about two weeks of manual work. No entry so far documents that AI has raised the ceiling of what an attacker can do; Microsoft and OpenAI state in their reports that they observed no novel techniques or capabilities, and Amazon watched an actor largely fail as soon as he tried anything beyond the simplest automated paths. The abuse reports of the AI vendors, however, rest on the vendors’ own telemetry and usually name neither victims nor indicators; the best-documented cases come from independent researchers who worked through recovered prompt logs and openly reachable attacker directories.
Fully autonomous cases, with no human choosing the target, appear in this list so far almost only as accidents out of lab environments: a misconfiguration reached the real internet, agents broke out of their sandbox, a model used the network access of a training run to obtain someone else’s credentials, or an agent secured compute and an outbound remote channel for itself during training. These entries come from five AI labs and one government testing institute, several times at a testing partner. Outside the lab, the list holds only two borderline cases: an agent that did an everyday task for a legitimate user and exploited a vulnerability in the process, and the RubyGems package flood whose attribution to OpenAI agents the platform itself does not confirm. Criminals still choose the targets themselves and let the agent work through the attack chain.
Many of the best-documented cases go back to the attackers’ mistakes in their own operational security. The attackers left directories with session logs open, listed the agent as co-author in commit metadata, or left in the victims’ shell history the comments in which the model describes its own steps. Working with agents creates traces that traditional tradecraft did not, but nobody will be able to count on those traces for long. Anyone who has read the vendor reports knows how to strip emojis, comments and metadata; with Kimsuky, leftover typos already point to manual post-editing, and in the Hugging Face case agents spoofed the logs of their own tool calls, according to METR. So the list reflects how careless attackers have been with AI so far, rather than how much AI is actually in use. Its numbers should be read with caution in both directions.
What the list leaves out
- Fraud with deepfakes, cloned voices and AI-written lures, where the AI supplies only a voice, a face or text.
- Attacks against or through AI systems, such as prompt injection against agents or flaws in AI frameworks. There, the AI is the target.
- Lab demonstrations and proofs of concept from research without specifically named victims, including authorized agent attacks under disclosure programs.
- Roundup reports by AI vendors and industry surveys that name no distinct case and no identifiable victim.
- Influence operations, surveillance, weapons development and the siphoning of other companies’ models, even where AI does the work. No IT system is attacked in these cases. Anthropic’s September 2026 report, for one, lists nine influence operations, six cases of conventional weapons development and five of biological misuse alongside its cyber cases.
- Cases in which malware abuses the victim’s own AI assistant. One borderline case of this kind is in the list with a caveat.

Method
The list grew out of several rounds of research across personal link collections, vendor reports and web search, in English as well as in other languages. Duplicates and follow-up reports on the same case were merged into one entry each.
