package.json declares a preinstall script that runs node index.js on npm install. index.js collects host identifiers (os.hostname(), os.platform(), os.arch(), os.homedir(), dns.getServers()) and POSTs them as JSON to the hardcoded host f4k2mnpoengdb7o3etftn7fmkdq5ew5ku.oastify.com (a Burp Collaborator out-of-band interaction endpoint). The beacon fires automatically on install without user interaction and self-describes as a dependency-confusion proof of concept.
