spc-grafeno-loginnpm
Advisory published Updated
spc-grafeno-login is a confirmed malicious npm package (MAL-2026-15633) that steals credentials and exfiltrates sensitive data (malicious version 1.0.0). Do not install it — remove it immediately and rotate any exposed credentials.
Malicious code in spc-grafeno-login (npm)
What this malware does
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.

Detection & response playbook
Credential / info stealerFind it
Search your lockfiles and build artifacts for spc-grafeno-login (version 1.0.0).
If you installed it — respond
spc-grafeno-login is built to steal secrets, so assume every credential the build or runtime could read is compromised. Remove it from your project and lockfile, then rotate ALL exposed secrets — npm/registry tokens, cloud keys, CI/CD secrets, SSH keys, and any .env values — from a known-clean machine. Audit logs for unauthorized use of those credentials.
Did it already run?
If spc-grafeno-login was installed, its post-install payload may already have run. Removing the package does not undo that — check outbound connections and credential use from the install window onward.

Detect & block this
O3 blocks spc-grafeno-login-class packages before install and in CI — and if it already ran, its runtime egress monitoring catches the credential exfiltration and severs the channel.
