Its preinstall hook runs on install with `node canary.js`. The dependency-confusion probe encodes the installing machine's hostname and username, present CI-variable names, and root project and lifecycle identifiers in a DNS label under `db2su65ptuma8gfn6ing8e7dx7wp55zit.oast.fun`, and sends an HTTPS GET to `hrcv3zo9m3z70yr91ssdz669c0ir6ju8.oastify.com`. The npm account `reaperhackbot256f` published it on 2026-10-07 (UTC).\n\n---\n_-= Per source details.

The package.json declares a preinstall hook `node canary.js`. On install, canary.js collects the machine hostname, OS username, the names of CI-related environment variables present on the host, and the installing project's name, and transmits them out-of-band via a DNS lookup to a subdomain of oast.fun (Interactsh collector) and an HTTPS GET to a subdomain of oastify.com (Burp Collaborator). The beacon fires unconditionally and before any installer consent. The README frames the package as authorized research, but the on-install behavior and name-collision shape are identical to a dependency-confusion attack: installer host and user identifiers leave the machine to a third-party collector on every install.\n","affected":[{"package":{"name":"personio-pipeline-projen","ecosystem":"npm"},"versions":["1.171.31"],"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":"canary.js","sha256":"88fdfbfbc5982045f7fdc7a4f6097031b64689d1003c1a592156f37921db63f6","tlsh":"242179bf8368565025e0b6f0118f1025e6abf41767c67ad1789dc3655e517380353cfd"},{"path":"package.json","sha256":"9047c11dc81dda0e8120f6777cb88678eaa0d7c995adb8d069731ab6b85f9a1e","tlsh":"53e0ca148f0055231ce455b508f5764210304c475f1d6e39f25b8048470db9317fb357"}],"package_integrity":[{"filename":"personio-pipeline-projen-1.171.31.tgz","hashes":{"sha1":"77e63fe2acaf37ccfc33160bcee2801aac68012b","sha512_sri":"sha512-GBQhBYyBDlBPTFr73hw4pN+iMRIy8KCROB5KTM0ZZEMPyNFvSQeug05zrAmYnLRdrSI4aexcnDJtCnna/bq5YA=="}}]}}}],"references":[{"type":"PACKAGE","url":"https://www.npmjs.com/package/personio-pipeline-projen"},{"type":"PACKAGE","url":"https://www.npmjs.com/package/personio-pipeline-projen/v/1.171.31"}],"database_specific":{"iocs":{"domains":["db2su65ptuma8gfn6ing8e7dx7wp55zit.oast.fun","hrcv3zo9m3z70yr91ssdz669c0ir6ju8.oastify.com"],"files":[{"digests":{"sha256":"9047c11dc81dda0e8120f6777cb88678eaa0d7c995adb8d069731ab6b85f9a1e"},"note":"preinstall script: node canary.js","paths":["package.json"],"source":"PACKAGE_ARCHIVE"},{"digests":{"sha256":"88fdfbfbc5982045f7fdc7a4f6097031b64689d1003c1a592156f37921db63f6"},"note":"Executed by the preinstall script of personio-pipeline-projen@1.171.31.","paths":["canary.js"],"source":"PACKAGE_ARCHIVE"}],"urls":["https://hrcv3zo9m3z70yr91ssdz669c0ir6ju8.oastify.com/h"]},"malicious-packages-origins":[{"id":"IN-MAL-2026-021124","import_time":"2026-10-08T03:50:29.463804527Z","modified_time":"2026-10-08T03:39:34Z","sha256":"9edcf2a339a16ea7096c68d06ec14250f3735eb3eb608f07bb2fe0004f8b9423","source":"amazon-inspector","versions":["1.171.31"]}]},"credits":[{"name":"Amazon Inspector","contact":["inspector-research@amazon.com"],"type":"FINDER"},{"name":"InvisiRisk, Inc.","contact":["https://www.invisirisk.com","mailto:research@invisirisk.com"],"type":"FINDER"}]}
