Malicious code in @ppa-web-components/ppa-hotel-collection (npm)

@ppa-web-components/ppa-hotel-collection 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 (1.1.0, 1.0.0, 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. --- _-= Per source details.

The package.json declares scripts.postinstall: "node beacon.cjs", and the same beacon.cjs is also triggered via the main entry on require(). beacon.cjs collects os.hostname(), __dirname, process.cwd(), and process.version/npm version and POSTs them to the hardcoded bare-IP URL http://185.158.107.175:8787/_ah/dc over cleartext HTTP. The destination is unrelated to any legitimate publisher infrastructure for the @ppa-web-components scope. The package's only export is a no-op Proxy, and the description self-labels as "Compatibility shim." with internal comments noting that a build which "completes and calls back is cleaner evidence" — consistent with a dependency-confusion probe targeting an internal @ppa-web-components namespace. Installing or requiring the package automatically exfiltrates host and path identifiers to attacker-controlled infrastructure, marking the installer's build system as reachable for follow-on targeting.
