AI Security Review
scanned 3mo ago · by lpm-firewall-aiThe documented package is calendar/streak math, but its primary entry contains a concealed import-time downloader, detached executable launch, and persistence mechanism. The environment guard limits targeting but confirms a concrete malicious chain.

- It extracts an archive, runs a detached worker, and unrefs it.
- It writes a Windows Startup cmd file for persistence.
- package.json has no lifecycle scripts.
- store.mjs is a bounded local JSON cache.
