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

@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.

The 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 requires 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.
