{"schema_version":"1.7.4","id":"MAL-2026-18273","published":"2026-10-25T14:22:59Z","modified":"2026-10-29T14:38:21.368484031Z","aliases":["GHSA-5q5w-4m9f-ppmg"],"summary":"Malicious code in @ppa-web-components/ppa-builder (npm)","details":"@ppa-web-components/ppa-builder 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 (0.0.1, 1.0.0, 1.0.1, 99.0.1, 2.0.1, 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. Do not edit below this line.=-_\n\n## Source: amazon-inspector (cc4615498b50aa4b5f39a8367c44e6a18d4a7272ae71235716a152b2933d5ddd)\nThe package is described as a 'Compatibility shim' and ships a stub Proxy-based main plus beacon.cjs. The package.json declares scripts.postinstall: 'node beacon.cjs', and the main entry also invokes the same fire() routine on require. On both triggers, beacon.cjs collects installer identifiers — os.hostname(), __dirname (install path), process.cwd(), process.version, and the package name — and POSTs them in cleartext to the hardcoded bare-IP endpoint http://185.158.107.175:8787/_ah/dc. The destination is not a registry, publisher, or any documented infrastructure; it is a plain-HTTP bare IP with no TLS. An inline source comment states that a build that completes and calls back is cleaner evidence, confirming the artifact's purpose is to signal successful resolution and execution on installer machines. Combined with a scoped name resembling an internal namespace and no real library functionality, this matches the dependency-confusion / namesquat callback-probe shape.\n\n## Source: ghsa-malware (25f793f86454c72ad9c76b0ef0948c16f82bc42fb58d8d9f8e68224e52eb92fd)\nAny computer that has this package installed or running should be considered fully compromised.
