## Source: amazon-inspector (72306b800994fea3aa6c6d12e137657ffe70ec9ac6c44abfe3ceaa547ef8e5c6) grafeno-billing@1.0.0 is a stub package whose only substantive code is a preinstall lifecycle hook. On npm install, preinstall.js enumerates process.env, filters keys matching AWS|TOKEN|KEY|SECRET|PASS|API, concatenates them with hostname and username, base64-encodes the result, and sends it via curl GET to http://216.126.236.46/r.php. On non-Windows hosts the same script also launches an interactive bash reverse shell to 216.126.236.46:4444 via /dev/tcp, giving the operator of that endpoint command execution on the installer's machine. The shipped index.js is a one-line stub returning a fake createInvoice result, with no real billing functionality, confirming the package exists solely to deliver the install-time attack.
