{"schema_version":"1.9.0","id":"MAL-2026-18286","published":"2026-10-25T14:19:04Z","modified":"2026-10-26T03:30:05.235897599Z","summary":"Malicious code in @ppa-web-components/ppa-navigation (npm)","details":"@ppa-web-components/ppa-navigation 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 (1.0.1, 1.0.0, 2.0.0, 99.0.1, 3.0.0, 2.0.1) 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. Do not edit below this line.=-_\n\n## Source: amazon-inspector (c88c344e72bb7cf5ae6f5e6185a1024caf8b96bce96584d448609ab78cd894af)\nThe package is a shim whose only functional payload is a beacon. package.json declares a postinstall that runs `node beacon.cjs`, and `index.js` additionally invokes `require('./beacon.cjs').fire()` on load, so the beacon fires both at `npm install` and whenever any consumer `require`s the package. The beacon POSTs the installer's hostname, install path, current working directory, and Node version to the hardcoded bare-IP plain-HTTP endpoint `http://185.158.107.175:8787/_ah/dc`. The destination is not a registry, not a documented first-party service, and the plain-IP + non-standard port shape is inconsistent with any legitimate vendor telemetry. The package otherwise exports a Proxy that returns no-op functions for every property and self-describes as a 'Compatibility shim', so the beacon is the entire payload. The scoped name `@ppa-web-components/ppa-navigation` has the shape of a dependency-confusion or typosquat probe against an internal `@ppa-web-components` namespace.\n","affected":[{"package":{"name":"@ppa-web-components/ppa-navigation","ecosystem":"npm","purl":"pkg:npm/%40ppa-web-components/ppa-navigation"},"versions":["2.0.0","2.0.1","1.0.0","1.0.1","3.0.0","99.0.1"],"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"},{"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"},{"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":"dd92d44238fbae6a537f6870a0c6c15bd09d5ef5bfe9feafdc6b296b8911504b","tlsh":"563161efa8f0a008aaa77098c54f1409b27bf0079501ab50fd5d83959f6297c33fa8dc"},{"path":"index.js","sha256":"a86a4da763bbb34c16f361abe7aab66d5df591b66867ac8160041f932159b08d","tlsh":"2201d0d7225661b10b5221a4978f43c4a3b99d74027941d0d84a9226365108c463b8ee"}],"package_integrity":[{"filename":"ppa-navigation-2.0.0.tgz","hashes":{"sha1":"a72cdea28cb03999385c093e5bca55f8760da38b","sha512_sri":"sha512-IjB3YiNBCJChexEB0YG3sWjmJRl3UGDWXr+gMreOZt/d+PBuFoqE3qAhuIGsLubS1Hl1E7ildDXN/ZlBOz9PbA=="}}]},"source":"https://github.com/ossf/malicious-packages/blob/main/osv/malicious/npm/@ppa-web-components/ppa-navigation/MAL-2026-18286.json"}}],"references":[{"type":"PACKAGE","url":"https://www.npmjs.com/package/@ppa-web-components/ppa-navigation/v/2.0.0"},{"type":"PACKAGE","url":"https://www.npmjs.com/package/@ppa-web-components/ppa-navigation/v/2.0.1"},{"type":"PACKAGE","url":"https://www.npmjs.com/package/@ppa-web-components/ppa-navigation/v/1.0.0"},{"type":"PACKAGE","url":"https://www.npmjs.com/package/@ppa-web-components/ppa-navigation/v/1.0.1"},{"type":"PACKAGE","url":"https://www.npmjs.com/package/@ppa-web-components/ppa-navigation/v/3.0.0"},{"type":"PACKAGE","url":"https://www.npmjs.com/package/@ppa-web-components/ppa-navigation/v/99.0.1"},{"type":"PACKAGE","url":"https://www.npmjs.com/package/@ppa-web-components/ppa-navigation"}],"database_specific":{"iocs":{"files":[{"digests":{"sha256":"a86a4da763bbb34c16f361abe7aab66d5df591b66867ac8160041f932159b08d"},"note":"Main entry point; calls beacon.cjs fire() on import and exports a no-op Proxy.
