If this package is installed
Remove it, treat the machine (or CI runner) as compromised, and rotate every secret, token and key it could access — from a different, clean machine.

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.
