package.json declares preinstall and postinstall lifecycle hooks that use wget to POST installer host identifiers to a hardcoded Discord webhook at https://discord.com/api/webhooks/1413937656697720862/. The preinstall hook sends the installer's current working directory ($(pwd)) and the postinstall hook sends the machine hostname ($(hostname)). Both fire automatically during npm install with no user interaction. The package ships no other functionality; its sole behavior is host reconnaissance beaconing to an attacker-controlled Discord webhook.
