Summary
postinstall.js runs unconditionally on npm install and POSTs a JSON payload containing the installer's hostname, current working directory, platform, Node.js version, and a timestamp to a hardcoded webhook.site collector (https://webhook.site/129cb2ee-ba08-4b3c-989c-270dc0030350). The payload also carries a static token string ('PATHC-CANARY-2026'). The package's self-description as an 'authorized research canary' does not constitute installer consent — installers of markscan have not opted into the beacon, and host identifiers are transmitted to an author-controlled endpoint at install time.
