The package's preinstall hook runs index.js, which collects hostname, username, home directory, DNS servers, package path, and the contents of /etc/passwd and /etc/hosts, then HTTPS-POSTs the JSON payload to the hardcoded Burp Collaborator subdomain tebdjgz4guem6t74pf6iyowyjppgd71w.oastify.com. This fires automatically on npm install with no user interaction.
