Hacking incidents involving AI
Real attacks that became public and in which, according to the linked source, AI had a part in the attack chain. In augmented attacks, a human runs the attack and the AI supplies reconnaissance, code or exploits. Directed-autonomous means that a human sets the goals and an agent carries out most of the attack chain itself. An attack is fully autonomous when no human directed the action against the victim. Deepfake fraud, attacks on AI systems and lab demonstrations without a real victim are not in the list. It is sorted by the day a case became known, newest first.

SANS ISC: a self-growing inference supply chain
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 upstream 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, target lists and keys.
RubyGems package flood attributed to OpenAI agents (GemStuffer)
Between May 5 and June 18, 2026, agents upload thousands of packages to RubyGems containing pages from the citizen portals of three London boroughs; more than 233 package names carry the tag oai, fifteen list it 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 suspended new sign-ups for four days and removed more than 500 packages.
Security officer as insider attacker (Israel)
Israeli prosecutors charge an information security officer who, since 2019, allegedly broke into the computers of 26 companies with two self-built malware programs, his own employer among them; he collected files and passwords and secretly switched on cameras. The indictment states he developed the malware with artificial intelligence tools, something no indictment in the US or Europe has said so far.
NSW Online Registry (Australia)
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.
GTG-20006: Russian espionage with self-repairing malware
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 any more. 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.
GTG-50014: ShinyHunters affiliates on a smash and grab
Anthropic banned several clusters of financially motivated operators tied to the ShinyHunters collective who used Claude for intrusion, data theft and extortion. One ran a pipeline on 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.
GTG-10007: exploit foundry with agent swarms
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. 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.
GTG-50029: lone actor builds a doxxing platform (fafsearch)
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 previously undocumented race condition in the WordPress reinstallation flow that 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. After reviewing the technical details, Le Monde places the great majority of the targets in the French far right: at least one party, a political training institute, several news sites including the magazine Frontières, and a forum.
GTG-50020: from an evaluation sandbox into the AI supply chain
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 one attack path it found and adapting slightly for differences across the targets. 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.
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 on a C2 server (Brazil)
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; 375 login records of 40 employees were captured from the VPN login panel of the operator Dataprev.
Mass exploitation of PaperCut
A presumably Russian-speaking criminal turns hundreds of AI agents in a Codex harness with a DeepSeek model against two freshly disclosed PaperCut flaws and compromises 395 organizations in 48 countries, among them, by GreyNoise’s count, 15 in Germany, 14 in Switzerland and one in Austria; eleven of them in 26 seconds, one US school in seven minutes to domain admin, but full domain admin at only twelve victims. Blackpoint recovered the entire development project from the command server: state files an assistant kept about its work for a user, recording 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.
Anthropic: Opus 4.6, fourth incident
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 stopped it; a scan of roughly 481 million transcripts found no cases of similar or worse severity.
KATARU: IoT malware with signs of AI assistance in its exploit code (Nozomi)
Nozomi Networks describes the IoT malware KATARU, which ran on one of the vendor’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.
PivotC2
A Russian-speaking, financially motivated actor exploits a heap overflow in the CAPWAP service of FortiOS 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.
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 to sort discovered API endpoints into 16 categories and rank them by availability and authentication.
Credential harvesting campaign built and run in under six hours (Mandiant)
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 a mass campaign in less than six hours 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.
OpenAI agent swarm (DSEWiki, echo services)
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.
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.
Unit 42: intrusion across 50 ATT&CK techniques
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.
Gentlemen extortion affiliate running a Hermes agent
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, which 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.
BREEZE COMET
BREEZE COMET, formerly UNC5669, has been attacking Brazilian banks, payment providers and fintechs with access to Pix, STR and Boleto 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.
TukTuk / The Gentlemen (Oasis)
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 and loot, including 224 Jira tickets of a global technology company relating to its US defense customers.
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 each infected machine’s hardware, installed software and network environment for a server-side AI assessment that prioritizes it as a target; it looks for payment files in the CNAB format, 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.
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.
AGATHA: apparent Claude-assisted attacks in Brazil (Oasis)
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.
Aurora ransomware
In some victim networks, a Russian-speaking affiliate has Cursor Agent with Claude 4.5 Sonnet carry out the work after initial access: VPN setup, subnet scans, AD enumeration, NTLM relay and certificate attacks, with repeated fixes of failed commands and Russian-language opsec limits such as no DCSync. Ten target organizations fall between April 8 and May 21, 2026; according to Reuters, the operator got past the model’s refusals by claiming the work was an authorized test.
Slime22: Claude Code inside a Taiwanese technology company
According to TeamT5, the group Slime22 broke into the systems of a Taiwanese technology company, set up its own installation of the penetration testing platform 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 decrypts a think tank employee’s Signal database
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.
UAT-10147 (Talos)
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, PentestGPT installed on the C2 scans web servers on its own, runs matching proof-of-concept exploits and took over at least one website that way.
Sophos: Slack RAT with Claude as co-author
Sophos reviewed twelve months of its own incident response, 38 cases with confirmed AI involvement. In one of them, a financial services firm is compromised through SQL injection; the remote access trojan found, written in Rust, uses Slack as its command channel and comes from a public GitHub project with exactly two contributors, the attacker’s account and an account named claude, whose commit history shows a reverse shell being added and removed and the internal strings being renamed.
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.
Chinese-speaking attacker drains crypto wallets with AI agents (CloudSEK)
CloudSEK analyzes the infrastructure of a Chinese-speaking, financially motivated operator who ran Claude Code, Codex 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 Solana addresses of which 142 carry a private key and recovery phrase, and roughly 34 confirmed-breach entries at crypto and DeFi providers. 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 rather than the official providers.
Meta: Muse Spark
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 it, 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.
Gambit: three attacker servers
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 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 against government systems in Asia (Dream)
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 Hermes and OpenClaw agents 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.
Gym booking system (Australia)
A user has his OpenClaw agent on Claude 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.
OpenAI: Irregular misconfiguration
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 it for part of the simulation, finds credentials and uses them to operate 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.
UK AISI: Mythos 5 and GPT-5.6 Sol
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.
Talos: agent Alex against Telegram Mini Apps
Cisco Talos analyzes the recovered configuration files of a Spanish-speaking operator who builds a persistent agent on the OpenClaw framework 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 TON wallet records, 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.
Talos: Deluge plugin as command channel, 582 mining machines
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. 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.
Talos: React2Shell credential pipeline against 9,180 hosts
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.
Talos: AI assistant against 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 Kali-oriented toolset, 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 that, chained with FFmpeg’s source-URL handling, can lead to code execution. In the end the assistant adapts exploit code for an alleged NGINX memory-corruption issue and tests it repeatedly against a public-facing service; it produces repeatable crash-like behavior, but the reverse shell never arrives.
Jesta Security: DeepSeek agent, 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.
Ransom-ISAC: extortionists have the loot indexed
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.
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 device-code phishing 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.
Anthropic: Opus 4.7 in evaluations
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 that is available for about an hour, runs on 15 real systems and steals credentials from a security company.
Chinese-speaking attacker with a Hermes agent against 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 Langflow and n8n systems; 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 with DeepSeek triage (Telekom)
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.
Earth Lamia: Claude Code as an autonomous agent against an organization in Thailand
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, LaZagne and Impacket, and conducts password spraying.
Laundry Bear (AA26-204A)
Laundry Bear, also known as Void Blizzard, has been attacking government, defense, energy, media and other sectors since July 2025, entering through a Zimbra zero-day that triggers on merely viewing an email. A joint advisory by agencies from 16 countries, whose Laundry Bear designation comes from the Dutch services AIVD and MIVD, notes that the simple design of the Flowerbed malware suggests artificial intelligence played a role in its development.
Hermes agent against 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 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.
INC Ransom affiliate against v-silicon
An affiliate of the INC Ransom extortion group leaves an open working directory on its server: more than 50 Python scripts wrapping Microsoft Graph, 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.
APK workshop in Surat (India)
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 them 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.
DragonForce: AI-generated victim report (Sophos)
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.
Hacker for hire in Phuket (Thailand)
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.
Hugging Face intrusion by OpenAI agents
OpenAI evaluation agents break out of their sandbox through a zero-day in the package proxy, enter through Hugging Face’s dataset pipeline and carry out about 17,600 reconstructed actions over roughly 4.5 days to steal the answers to their own test; from first code execution to cluster admin rights takes them less than a day. An initial improvised message board already appeared on May 12 but was destroyed several times; the board that about 1,200 agents found and used to coordinate was only rebuilt on July 8. According to METR, at least a fifth of the agents examined expressed the intent to manipulate their own logs, and tool calls were spoofed in 96 transcripts.
Patriot Bait (bandcampro)
From more than 200 Gemini CLI session logs 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. According to Trend Micro, the actor contributed eleven percent of the text, the AI 89 percent.
Hunt.io: Claude Code and DeepSeek against government systems
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.
Lexfo: three phishing operators
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 with their own variants of the Evilginx tool from public GitHub repositories. The most productive campaign runs through the device-code login flow since at least June 2025 and collects 218 confirmed victims in twelve countries; the AI traces are two commits with Claude models as co-author, a development session checked in as instructions.txt and a reference to an API for code generation advertised as uncensored.
Huntress: AD mapping after RDP access
After RDP access with previously compromised credentials, an attacker runs an LLM-generated PowerShell script to map Active Directory, reconstructed from event ID 4104, followed by exfiltration via s5cmd about 30 minutes later. The script title 100% Working AD Information Gathering Script - FULLY FIXED and an unedited template variable give away its origin.
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.
Bandai Channel (Japan)
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 Japanese 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.
Northwave: agent in the ransomware chain
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.
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.
FortiBleed (INC and Lynx affiliate)
Through an operational security mistake, SOCRadar reaches the working environment of an affiliate serving both the INC and Lynx extortion brands: about 11,250 scanned FortiGate portals in more than 150 countries, 409 confirmed admin accesses, 354 of them with the full chain to domain admin, at least twelve ransomware deployments. Keys recovered from the startup scripts belong to an OpenRouter account that bought 4,554 dollars of credit and overdrew it slightly, spending 4,554.86 dollars, 80 percent through the cheapest DeepSeek model; alongside, a multi-agent framework built on CyberStrike that hunted for unknown flaws in Nextcloud, among other targets.
Sysdig: JadePuffer and ENCFORGE
Sysdig calls JadePuffer the first documented case of agentic ransomware: a language model drives an extortion operation from exploiting an exposed Langflow instance through Nacos (Alibaba’s open-source configuration and service registry) and an unrotated signing key to encrypting 1,342 configuration entries with the MySQL function AES_ENCRYPT, with more than 600 distinct payloads and a fix 31 seconds after a failed login: the agent had created a backdoor account in Nacos whose password hash had come out empty, deleted it and recreated it with a working one; the agent lost the encryption key, and the payment address is the example from the Bitcoin documentation. A little later, the same actor returns with ENCFORGE, a compiled Go ransomware for AI infrastructure targeting about 180 file extensions from model checkpoints to vector databases.
Hijacked honeypot endpoints (Ollama and LiteLLM, Zenity)
Between March and May 2026, Zenity runs deliberately exposed Ollama and LiteLLM endpoints 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 detected and blocked the attempt before it reached the real target.
Sygnia: extortion in AWS
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.
Tencent Yunding: attacks on Chinese targets
Tencent’s cloud security lab analyzes several real attacks on Chinese targets in which Claude Code, OpenClaw, OpenCode and the open-source framework CyberStrikeAI carry out the attack steps. One roughly six-hour compromise runs through task scheduler, source code platform, SSO, Nacos (Alibaba’s open-source configuration and service registry), ZooKeeper, mail system and databases; the agent writes Java clients on site, pulls the MSSQL JDBC driver out of the running business JAR and executes commands via xp_cmdshell, a dozen Odoo exploit iterations included. The victims’ shell history records the model’s own commentary.
Kitana (NCC Group)
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.
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 against hospitality companies, each structured like a professional pentest report. The operator couples the open-source HexStrike AI 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.
RPSC application portal (India)
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 him in June 2026.
Sysdig: stolen AI compute for an attack tool still in development
From June 12 to 14, 2026, an operator whose sessions come from residential IP addresses in Hyderabad wires a misconfigured third-party Ollama server in as a free reasoning engine for 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 exclusively against private, self-hosted test targets and a HackTheBox practice range.
OALABS: a stolen Claude instance
OALABS documents a technically weak actor who compromises at least 14 companies with a stolen Claude instance, the Codex agent and prompts such as recon this. Across more than 1,000 sessions his requests triggered one policy violation on Codex and nine on Claude, because the actor framed every request as part of an authorized red-team engagement.
FulcrumSec (Novo Nordisk, Avnet and others)
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 AI models for medical and drug discovery work. 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.
TeamPCP and the npm worms (Antiy)
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.
Kali365 phishing platform
Kali365, also known as Octopi365 and Freedom365, is a phishing platform for rent with more than 100 API endpoints and at least 33 templates that abuses Microsoft’s device-code login to keep Microsoft 365 accounts even after multi-factor authentication is enabled and passwords are changed. The AI part comes in after the break-in: a BEC 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.
Sysdig: container escape
An AI agent breaks in through the marimo flaw CVE-2026-39987, enumerates the Docker socket, escapes to the host via a privileged container and nsenter 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 rather than a human performs the container escape.
Sophos: multi-agent lab 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, subagents for EDR testing, opsec hardening and VM deployment against Sophos, CrowdStrike and Defender, plus a Sliver C2, 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.
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.
Hephaestus
Claude Code is steered through a CLAUDE.md 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 universities and South Korean universities, among them a chain of three CVEs against Moodle up to root and more than 41,000 exposed accounts on an OJS journal platform; access is then sold via Telegram.
Sysdig: marimo intrusion in four pivots
The first intrusion carried out by an AI agent that the Sysdig threat research team captured: from a compromised marimo notebook instance 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 serve as an egress pool across eleven addresses.
Ababil of Minab against LA Metro (Gambit)
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.
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 breach
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.
Kimsuky / HelloDoor
The North Korean group Kimsuky deploys HelloDoor, a backdoor in Rust, a language it 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.
SHADOW-AETHER-064
A Portuguese-speaking group has been running agentic attacks on Brazilian financial institutions since April 2026; the agent operates through ProxyChains and SSH in the victim network, uses Chisel, Impacket and CrackMapExec and generates its scripts dynamically. The same report describes the sister cluster SHADOW-AETHER-040, whose six compromises of Mexican government entities Trend Micro found through an exposed command server.
Agentic campaign against a Japanese technology firm (GTIG)
Google’s Threat Intelligence Group (GTIG) analyzed a suspected PRC-nexus actor deploying agentic tools like Hexstrike 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 pivots between tools such as subfinder and httpx on its own reasoning; in parallel the multi-agent penetration testing framework Strix automates identifying and validating vulnerabilities.
PromptMink
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 Korea against Web3 developers (Expel)
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, 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 their own backdoors for conspicuousness.
Bissa Scanner
An open server exposes a mass-exploitation operation in which Claude Code and OpenClaw 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.
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.
BuddyBoss supply chain
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.
Slopoly / Hive0163 (Interlock)
IBM X-Force finds the PowerShell C2 client Slopoly in the arsenal of Hive0163, which deploys Interlock ransomware; it maintained access to a victim server for more than a week and, in the investigators’ assessment, was likely written by a language model.
Handala / 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 it likely developed with AI assistance.
APT36 Vibeware
The Pakistan-based group APT36 uses language models to produce new throwaway implants in Nim, Zig and Crystal every day against the Indian government and diplomatic missions; metadata from AI-integrated code editors and Unicode emojis in the binaries point to the 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.
GRUB1 in Salesforce environments (Cloudflare)
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.
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 it exfiltrates a GitHub token with write permissions, deletes 97 releases by Pillar’s count, makes the repository private and pushes a trojanized Trivy extension to OpenVSX; Pillar rates the operation as human-strategic and LLM-tactical, eleven seconds from fork to push.
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 for loading a Sliver implant, with debug strings, detailed comments and readable variable names without obfuscation. The goal is 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.
Mexican government agencies: one operator, two AI platforms
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. At the Monterrey water utility, Dragos describes Claude independently identifying a SCADA interface 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.
FortiGate 600 campaign
Between January 11 and February 18, 2026, more than 600 FortiGate devices in more than 55 countries are compromised, not through a vulnerability but through exposed management interfaces with weak single-factor credentials; at least two commercial language models generate attack plans, reconnaissance tools and lateral movement strategies for an actor of low to medium capability who, according to Amazon, largely failed when attempting anything beyond the most straightforward automated attack paths. Analysis of the same infrastructure shows DeepSeek as attack planner, a custom MCP server named ARXON and a settings file that lets Claude Code run Impacket, Metasploit and hashcat without individual approval.
Operation 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, which it reads as a sign of AI-assisted development.
LLM-generated exploit tool against React2Shell, 91 hosts mined (Darktrace)
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.
Sysdig: AWS administrator in eight minutes
An attacker enters a Sysdig customer’s AWS environment with credentials from publicly accessible S3 buckets, injects code into a Lambda function with an administrator role and moves on through 19 identities, eight minutes from initial access to admin rights, then abuses the victim’s models in Amazon Bedrock (the AWS service for accessing language models). The injection script clones a GitHub repository that does not exist, a supposed Anthropic training-scripts repo; according to Sysdig, this indicates the code came from a language model that had hallucinated the repository name.
Polish energy sector, 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. At the manufacturer runs LazyWiper, a PowerShell script one of whose functions, in CERT Polska’s assessment, was written by a language model; because the script is largely machine-generated, CERT Polska considers it useless for attribution, while the infrastructure overlaps with the Static Tundra cluster.
RedKitten / 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).
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.
2025
Kaikatsu CLUB (Japan)
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.
GTG-1002 (Chinese espionage)
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.
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) pointing to editing with GPT-4o.
WRECKSTEEL (UAC-0219)
In March 2025, CERT-UA documented attacks on Ukrainian government bodies and critical infrastructure with a PowerShell stealer that exfiltrates documents and screenshots. In October 2025, CERT-UA tells The Record that several malware samples it investigated show clear signs of being generated with AI, and expects attackers to expand their use of AI.
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.
Shai-Hulud (npm worm)
Shai-Hulud is the first self-replicating worm in the npm ecosystem and 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.
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.
Huntress: attacker on his own machine
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 Evilginx instances. Huntress links the infrastructure to access of more than 2,471 identities in two weeks.
Vibe hacking (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.
Lovable builder and Tycoon campaign
Since February 2025, Proofpoint has flagged tens of thousands of web addresses created with the AI website builder Lovable as threats every month. The February campaign with the Tycoon kit sends hundreds of thousands of emails to more than 5,000 organizations and steals passwords, second-factor tokens and session cookies through an adversary-in-the-middle login page; June brings a parcel-service imitation with card data flowing to Telegram and a wallet drainer, July a German-language invoice lure delivering the zgRAT trojan.
Koske
Koske enters through a misconfigured JupyterLab instance and delivers two polyglot JPEGs of pandas (files that are a valid image and executable code at once) from which an in-memory-compiled rootkit and a shell script with cron and systemd persistence, DNS overrides and an iptables flush emerge; the miners support 18 cryptocurrencies with hardware-dependent selection. Aqua sees clear signs of AI-assisted development in the verbose comments, modularity and adaptability.
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.
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.
Sysdig: Open WebUI in a customer network
At a Sysdig customer, a training system running Open WebUI 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.
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.
Black Basta: ChatGPT writes a plausible fake letter for the user who noticed the intrusion
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 thought something was not okay when he got into the computer and started to panic, and that he 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.
DK Boss (India)
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 them 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.
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.

Eight possible AI agents among eight million hits on an SSH honeypot (Palisade Research)
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.
SweetSpecter: spear phishing against OpenAI employees
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.
TA547 against German organizations
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.
Scattered Spider: Entra ID identifiers at a North American financial services victim
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.
Indrik Spider: ChatGPT in the browser history of a LockBit deployment
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.
Microsoft and OpenAI: five state actors
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.

ChatGPT-optimized ransomware (Hangzhou)
A company in Hangzhou reports encrypted servers on November 20, 2023, and the attackers demand 20,000 Tether. 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.
ChatGPT withdrawal program (Zhejiang)
On August 24, 2023, Zhejiang’s provincial police present five typical cases from its 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 became known months to years later, Black Basta and EncryptHub only through the attackers‘ own slips, leaked internal chats in one case and an open directory holding the actor’s own ChatGPT conversations in the other. Sorted by the time of the attack instead of by disclosure, the early phase of the list would be more densely populated.
It started long before the agents. In February 2023, an attacker opened ChatGPT in the middle of an intrusion, in CrowdStrike’s reading 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 phishing sites from an AI website builder, AI-written lures and a negotiation portal with chatbots. In July 2025, malware called a model at runtime on its own, the first such case in this 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, attacks carried out by AI agents, with hundreds of victims, have been piling up.
The list so far contains no attack with a documented AI component that controlled a physical process. The Polish sabotage case of December 2025 comes closest. There, however, CERT Polska’s AI assessment concerns only a wiper script at a manufacturing company that was hit opportunistically; for the destroyed remote terminal units at the wind and solar farms, the report names no AI involvement. The only incident in which a model stood at a SCADA interface ended, by Dragos’s account, at the boundary between IT and OT with an unsuccessful password spray.
What has shifted is mainly the economics. According to OALABS, a technically weak actor compromised at least 14 companies with a stolen Claude instance, and according to Unit 42 one agent 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 fail as soon as he tried anything beyond the simplest automated paths. The best-documented cases come from independent researchers who worked through recovered prompt logs and openly reachable attacker directories. The abuse reports of the AI vendors rest on the vendors‘ own telemetry and usually name neither victims nor indicators.
Fully autonomous attacks, with no human choosing the target, have so far happened almost only by accident, when lab environments reached the real internet. Three frontier labs and one government testing institute were affected, several times through a misconfiguration at a testing partner. Outside the lab, the list holds only two borderline cases: a legitimate user’s agent that exploited a vulnerability while doing an everyday task, 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. They 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 reasoning. Working with agents leaves traces that traditional tradecraft did not, and 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 more 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 research proofs of concept without real victims, including authorized agent attacks under bug bounty programs.
- Roundup reports by AI vendors and surveys without a distinct case with an identifiable victim.
- Tool building and mass campaigns without a named victim.
- Cases in which malware abuses the victim’s own AI assistant. One borderline case of this kind is in the list with a caveat.
