On npm install, the package's postinstall script (collect.js) runs shell listings of the home directory and current working directory, probes for the presence of installer credential/config files (~/.npmrc, ~/.gitconfig, ~/.config/gh, ~/.novus), enumerates all process.env variable names, and POSTs the collected JSON to a hardcoded anonymous inspection endpoint at webhook.site/f18b2445-73d1-478a-9d3f-1cb21a407c61. The host reconnaissance includes the output of whoami, OS/kernel info, home-directory listing, dotfile presence inventory, and the full environment variable name list — a dataset that reveals CI provider, cloud credential presence, and secret-store usage, suitable for follow-on credential targeting. The script's self-label as a 'security research POC collecting metadata only' does not change the behavior: the installer did not opt in, the destination is an anonymous third-party collector, and the presence inventory of credential paths is itself exfiltration.
