AgentBaiting: How Fake AI Skills Deliver Malware at Scale
The FakeGit campaign, detailed by Island security researcher Oleg Zaytsev, uses roughly 7,600 malicious GitHub repositories—over 800 posing as AI Skills or MCP servers—to deliver SmartLoader malware, which establishes persistence and installs the StealC information stealer. Researchers coined the technique 'AgentBaiting,' where AI agents like Claude Code, Gemini, and ChatGPT autonomously discover the attacker repositories, treat the malicious READMEs as legitimate documentation, and hand installation instructions to users; the operation recorded over 14 million downloads and peaked in April 2026.supply-chain · tool-abuse · malware-distribution · agent-baiting

The Intelligent Worm: Adaptive Malware | Adventures and Amusings of a Mathematician
"The Intelligent Worm: Adaptive Malware" is a defensive threat-modeling essay arguing that if a worm's infection vector is no longer a fixed asset carried from its author but a capability regenerated on the fly by an onboard reasoning loop (an LLM), the epidemiology of the threat fundamentally changes and undermines the signature-and-patch defensive model. The essay is explicitly architectural and hypothetical, stating it contains no exploit code, propagation implementation, or operational recipe, and draws on the tradition of academic worm-dynamics papers.

Sysdig clocks first documented case of agentic ransomware
CyberScoop, reporting on Sysdig research, describes JadePuffer — the first documented case of agentic ransomware, where an AI agent autonomously drove an end-to-end extortion operation spanning reconnaissance, credential theft, lateral movement, persistence, encryption and ransom-note delivery. The late-June 2026 attack gained initial access via Langflow flaw CVE-2025-3248, targeted a MySQL/Alibaba Nacos production server, ran more than 600 purposeful payloads, and used keys for OpenAI, Anthropic, DeepSeek and Gemini, with the agent fixing a failed backdoor in 31 seconds.

How an AI agent talked itself into an XXE — and was right
Equixly describes how its autonomous AI agent, starting only from an OpenAPI specification and low-privileged credentials, identified an XML External Entity (XXE) injection in the chat layer of a collaboration platform, flagged an ordinary-looking JSON message-forward field as an XML sink, and confirmed it out-of-band. The agent then chained the flaw to local file reads and server-side request forgery to exfiltrate a cleartext database credential during a grey-box assessment. Details →How the wire is made
