 "notes": "'AgentBaiting' is the novel element: repositories are SEO'd so that Claude, Gemini and ChatGPT surface and install them without a user-supplied link, i.e. the agent is the delivery vector. Reported by Island's research team (Oleg Zaytsev) exclusively to The Hacker News; no standalone vendor writeup was reachable, hence medium confidence. The 14M download figure covers the whole campaign, not just the AI-themed repos.",
