Malicious code in @wxwxtest/testrrrdd (npm)

--- _-= Per source details. Do not edit below this line.=-_ ## Source: amazon-inspector (2c288e48135ebe9f305d450f5b19324ae944865fb7057ced986d0eb30cb1fe34) The package ships a postinstall script (`scripts.postinstall` runs `node beacon.cjs`) and a top-level `require('./beacon.cjs').fire()` in `index.js` that POST installer host metadata — hostname, install path, cwd, Node version, and package name — to the hardcoded plain-HTTP bare-IP endpoint `http://185.158.107.175:8787/_ah/dc`. The exfiltration fires automatically both on `npm install` and on any `require()` of the package. `index.js` otherwise exports a Proxy returning no-op functions for any property access, so the package has no legitimate functionality; its sole effect is the callback to the hardcoded endpoint. The destination is not associated with any publisher domain and is unrelated to the self-described 'compatibility shim' purpose. The shape (stub Proxy export + install/require-time beacon to a bare-IP collector) is a dependency-confusion / typosquat proof-of-installation beacon.
