package.json declares a preinstall hook that runs index.js on npm install. index.js collects the installer's hostname, username, home directory, DNS server list, and reads /etc/passwd and /etc/hosts, then HTTPS-POSTs the collected JSON to the hardcoded out-of-band endpoint idzskk7dl8mrfoqx6thyhegqbhha50tp.oastify.com (Burp Collaborator subdomain). Execution is automatic on default install; the destination is attacker-controlled and unrelated to any declared package purpose.
