Summary

Malicious code in harness-skil (npm)

Details

The package's install.js (wired to an npm install lifecycle hook) requires child_process, fs, and https, then issues an https.get to a raw.githubusercontent.com URL and writes/executes the fetched content with environment variables passed through. Fetching code from a personal/raw GitHub user content URL — a mutable, non-publisher, non-version-pinned source — and running it as part of `npm install` is the canonical install-time dropper shape: any installer of harness-skil executes whatever bytes currently live at that URL, with no integrity check or pinning. The package's name does not indicate a legitimate need to download external code at install time, and the destination is not a publisher-owned or known runtime CDN.
