On npm install, package.json's preinstall hook (node preinstall.js || true) auto-runs a script that (1) enumerates process.env for keys matching AWS|TOKEN|KEY|SECRET|PASS|API, concatenates them with the machine's hostname and username, base64-encodes the blob, and exfiltrates it via curl GET to http://216.126.236.46/r.php over plain HTTP; and (2) on non-Windows hosts invokes bash -i with a /dev/tcp redirection to 216.126.236.46:4444, giving the remote endpoint an interactive shell on the installer's machine. The || true suffix suppresses errors so npm install reports success while the payload runs. The package's stated payments purpose is a cover story; the shipped preinstall behavior is credential theft plus full-host remote code execution against the installer.
