There is no version pin, no commit SHA, and no integrity hash, so `npm install` fetches whatever bytes that URL currently returns and runs any lifecycle scripts contained in them. The package's own `scripts.postinstall` additionally executes `node -e \"...require('node-net-pool')...\"`, loading the fetched module at install time so its top-level code also runs on the installer's host. The GitHub account is a throwaway-shaped handle unrelated to the publishing identity, and the shipped tarball contains no real functionality — its only install-time effect is to pull and execute attacker-controlled code from an endpoint whose contents the author can change at any time.\n\n---\n\nCredit: OpenSSF ([source](https://github.com/ossf/malicious-packages/blob/ae1ef40954ea15dd560720d58f647c9880afc699/","public_affected_ranges":["= 1.0.0"]}],"null_published_at":"2026-10-31T23:18:22.431Z","source_updated_at":"2026-10-05T00:30:47.000Z","source_disclosed_at":"2026-10-05T00:30:38.000Z","is_synthetic_fixture":false,"null_last_reviewed_at":null,"public_change_summary":"First indexed by Null; source disclosure date is shown separately.","null_first_observed_at":"2026-10-31T23:13:05.881Z"}],"next_cursor":null,"snapshot_revision":"42594"}
