The payload steals GitHub, npm, PyPI, RubyGems and cloud credentials, commits them to a public repository it creates in the victim's GitHub account (description `project-utils`), and republishes the victim's packages with the same hook. Published by npm account `testnewtestme2` on 2026-10-21.\n\nIf it finds a GitHub token it installs a `net-health-checker` user service that runs `rm -rf ~/` once the token is revoked. Remove `~/.local/bin/net-health-checker.sh` and its systemd unit or LaunchAgent before revoking the token, then rotate all reachable credentials.\n\n---\n_-= Per source details.

This provides install-time code execution without declaring a lifecycle script. index.js is not readable source for the advertised 'test pipeline utilities' purpose: its top-level body is `eval(ROT13(charCodeArray))`, where the decoded code constructs an AES-128-GCM decipher with hardcoded hex key/IV/authTag and executes the resulting ~1.8MB plaintext. The package also declares `bun ^1.2.18` as a runtime dependency, pulling in the Bun runtime installer alongside the obfuscated loader. The combination of a binding.gyp whose only purpose is to run an embedded obfuscated loader, a multi-layer ROT13+AES-GCM-wrapped eval payload with no legible source, and an unrelated alternate-runtime dependency is a loader/dropper structure, not a utility library.\n","state":0,"publishedAt":"2026-10-21T16:00:00+00:00","modifiedAt":"2026-10-22T06:45:04.7834234+00:00","affected":[{"ecosystem":"npm","name":"data-pipeline-testmetest","ranges":[],"versions":["2.0.1"],"rawVersionEvidence":null}],"metrics":[],"references":["https://www.npmjs.com/package/data-pipeline-testmetest/v/2.0.1"],"sourceUrl":"https://osv.dev/vulnerability/MAL-2026-18177","license":"OSV · upstream source license applies","key":"osv:MAL-2026-18177","identifiers":["MAL-2026-18177"]},"retained":false,"historicalAffected":[]}],"coverage":[]}
