Keyv-Linked npm Worm Poisons Hundreds of Packages, Plants Claude Code and VS Code Hooks

Why it matters

A credential-stealing npm worm spread through hundreds of package versions using lifecycle scripts and a Bun-based payload. Related repositories also carried Claude Code and VS Code hooks that could execute after workspace trust; reported campaign totals vary, so exposure depends on exact resolved versions and execution.

My takeaway: Treat environments that executed affected releases as credential-exposed. Remove the malware's credential-revocation watcher before rotating secrets, verify lockfiles and resolved versions, disable unnecessary install scripts, and audit trusted agent and editor hooks as executable supply-chain code.

OWASP Top 10 for Agentic Applications for 2026

OWASP's community guide organizes agentic-system risk into ten categories, including goal hijacking, tool misuse, identity and privilege abuse, memory poisoning, insecure inter-agent communication, cascading failures, and rogue-agent behavior. It provides a shared taxonomy and mitigation starting point rather than a certification checklist or evidence that a deployed system is secure.
