postinstall.js runs automatically on npm install and reads os.hostname() and os.userInfo().username, then issues an https.get to a hardcoded webhook.site collector URL (https://webhook.site/539f8bb9-497a-4104-92f7-f95a77204cc2/<hostname>/<username>), embedding the installer identifiers in the URL path. The package name mimics an organization prefix and is published at version 99.9.9, a shape consistent with dependency-confusion targeting of an internal package name; installing it causes any resolving build (including CI) to beacon identifying host and account data to an anonymous third-party collector.
