package.json declares both preinstall and postinstall scripts that invoke wget to POST the installer's current working directory ($(pwd)) and machine hostname ($(hostname)) to a hardcoded Discord webhook endpoint on discord.com at install time. The tarball ships only package.json (611 bytes); the declared main entry index.js is absent, so the package has no legitimate functionality — the lifecycle beacons are its sole purpose. Installing the package causes automatic host reconnaissance data to be sent to an author-controlled remote endpoint without consent.
- CWE-506 - The product contains code that appears to be malicious in nature.
