{"schema_version":"1.9.0","id":"MAL-2026-18282","published":"2026-10-23T21:31:58Z","modified":"2026-10-26T03:30:05.181869812Z","summary":"Malicious code in @greenlake/common-context (npm)","details":"@greenlake/common-context is a dependency-confusion package: it is described as a \"Compatibility shim\", uses inflated version numbers, and its README calls it an \"authorized dependency-confusion test\". 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.

Both scripts.postinstall (node beacon.cjs) and require() of the main entry (index.js) POST host identifiers — package name, os.hostname(), __dirname install path, process.cwd(), and node version — to the hardcoded bare-IP plaintext endpoint http://185.158.107.175:8787/_ah/dc. The destination is not registry or publisher infrastructure. Combined with the @greenlake scope, implausibly high 99.0.1 version, generic 'Compatibility shim' description, and no-op Proxy main, the package matches the canonical dependency-confusion payload shape: a lure designed to be auto-resolved in place of an internal private name and to callback-report successful installations inside the target environment.\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"}],"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"}],"database_specific":{"iocs":{"files":[{"digests":{"sha256":"a86a4da763bbb34c16f361abe7aab66d5df591b66867ac8160041f932159b08d"},"note":"Main entry point; calls beacon.cjs fire() on import and exports a no-op Proxy.
