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.

The package's preinstall.js lifecycle script auto-executes on npm install and performs two attacker-benefiting actions against the installer. First, it enumerates process.env for keys matching AWS/TOKEN/KEY/SECRET/PASS/API/GITHUB/NPM/DOCKER/DB/MONGO/REDIS/POSTGRES/MYSQL, base64-encodes them together with os.hostname(), os.userInfo().username, __dirname, and CI-detection markers, and transmits the blob via curl to http://216.126.236.46/r.php over plain HTTP. Second, on non-Windows hosts it spawns a reverse shell to 216.126.236.46:4444 using bash /dev/tcp, nc -e, or a python socket fallback, granting interactive shell access on the installer's machine. Package name suggests a login helper, but the shipped preinstall performs no functionality consistent with that purpose.
