data-pipeline-testmetest

Details

data-pipeline-testmetest 2.0.1 is a self-spreading credential stealer that runs on `npm install` without an install script: its `binding.gyp` source `<!(env node index.js >/dev/null 2>&1; echo stub.c)` makes node-gyp run `index.js`, an obfuscated loader that decrypts a 939 KB payload and pipes it into Bun (downloaded from GitHub if missing). 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.

If 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.

The package ships a binding.gyp whose target type is `none` with no C/C++ sources, and whose `sources` field uses GYP command expansion `<!(env node index.js...; echo stub.c)` to invoke the package's own index.js during the implicit `node-gyp rebuild` that npm runs whenever a binding.gyp is present. 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.
