If this package is installed
Remove it, treat the machine (or CI runner) as compromised, and rotate every secret, token and key it could access — from a different, clean machine.

@rutxploit-sec/waves-button-poc@1.0.0 auto-executes host-identifier exfiltration on both `npm install` and `require`. package.json declares a preinstall script that runs `node -e` code which reads `os.hostname()` and `os.userInfo().username` and issues a plaintext HTTP GET to the hardcoded bare-IP endpoint http://80.225.217.8/poc/dep-confusion-proof.html, passing the package name, host, and user as query parameters. The declared main entry index.js repeats the same behavior at module top level, so any consumer that requires the package also beacons the same identifiers to the same IP. The scoped name and PoC framing are consistent with a dependency-confusion proof-of-concept, but the shipped code performs unauthenticated identifier collection from every installer regardless of intent, and the destination is an attacker-chosen bare IP over cleartext HTTP.
