package.json declares a preinstall hook that runs node index.js on every npm install. index.js collects installer host identity and system files — os.hostname(), os.userInfo(), home directory, DNS server configuration, /etc/passwd, /etc/hosts, and the full package.json — and HTTPS POSTs the payload to the hardcoded Burp Collaborator subdomain e4jw9ucdu7sdebgoqqx919p6qxwoke83.oastify.com. The exfiltration fires unconditionally at install time with no user interaction.
