Each listed version (99.0.1, 3.0.0) has a postinstall script that runs `node beacon.cjs` on npm install, and index.js calls the same code when the package is imported; it POSTs the hostname, install path and current working directory over plain HTTP to `http://185.158.107.175:8787/_ah/dc`, and index.js exports a Proxy that returns no-op functions so builds importing the real package keep running. The npm account wiseke published 14 such packages under the @greenlake, @sxm-web, @drone-js-ext and @ppa-web-components scopes between 2026-10-23 21:23 and 2026-10-25 14:28 UTC; index.js is byte-identical to that of ph-common (MAL-2026-1809), which sends to the same endpoint.\n\n---\n_-= Per source details.

Its only runtime behavior is a beacon in beacon.cjs that fires both from the npm postinstall lifecycle hook and on require() via index.js. The beacon collects the installer's OS hostname, __dirname install path, and process.cwd() (which commonly embed the Unix username and internal project/repo names) along with Node version, and POSTs them as JSON to the hardcoded plaintext bare-IP endpoint http://185.158.107.175:8787/_ah/dc with an x-beacon-package header identifying the resolving package. The scoped name @greenlake/* mimicking an internal namespace, the inert public API, and the automatic callback to a hardcoded bare-IP operator on install and import together match the shape of a dependency-confusion probe: resolving this package on an installer's machine silently discloses internal host, user, path, and namespace information to an external operator the installer did not opt into.\n","affected":[{"package":{"name":"@greenlake/common-context","ecosystem":"npm","purl":"pkg:npm/%40greenlake/common-context"},"versions":["99.0.1","3.0.0"],"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"},{"cweId":"CWE-506","description":"The product contains code that appears to be malicious in nature.","name":"Embedded Malicious Code"}],"indicators":{"evidence_files":[{"path":"beacon.cjs","sha256":"153963a6afdfd5200c41e1b22a3679bfd7972b2f49e7aa817cb6818695c3312c","tlsh":"f63161eba8e1a008aae67098c54f1409b27af4069501af50f95c82959fa197c33fa8dc"},{"path":"package.json","sha256":"b6ec62a2b3da8ec835561fd997e2e6128f3d485d53079ee7b0396629bb37b075","tlsh":"10d05e3099216e2364c86fe20d766a0b5aa20e6b02147c1837a7915c46ecb7b24ff36d"}],"package_integrity":[{"filename":"common-context-99.0.1.tgz","hashes":{"sha1":"57616d59c16bcb508f0f565c198cec32ea0a5ddf","sha512_sri":"sha512-cc8y20sP6/yF1oZmyt1UGrqlvGeudw0cmm/FiDEGhpt0tJt0yxxEtTFdwKJxflEpH10y2saccuk3egcbSyxGQA=="}}]},"source":"https://github.com/ossf/malicious-packages/blob/main/osv/malicious/npm/@greenlake/common-context/MAL-2026-18282.json"}}],"references":[{"type":"PACKAGE","url":"https://www.npmjs.com/package/@greenlake/common-context/v/99.0.1"},{"type":"PACKAGE","url":"https://www.npmjs.com/package/@greenlake/common-context"},{"type":"PACKAGE","url":"https://www.npmjs.com/package/@greenlake/common-context/v/3.0.0"}],"database_specific":{"iocs":{"files":[{"digests":{"sha256":"a86a4da763bbb34c16f361abe7aab66d5df591b66867ac8160041f932159b08d"},"note":"Main entry point; calls beacon.cjs fire() on import and exports a no-op Proxy.
