Which versions of sufetch are malicious?

The following npm versions of sufetch are flagged malicious: 0.4.1. Treat any of these as compromised.

How do I remediate sufetch if I installed it?

sufetch 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.

I already installed sufetch — how do I know if it already compromised me?

If sufetch 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.

Is sufetch part of a known attack campaign?

Yes — sufetch is associated with the GHSA-x8hh-3gmf-mm9r 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 sufetch across my projects, lockfiles, and CI pipelines?

Search your lockfiles and build artifacts for sufetch (version 0.4.1).

Malicious package

Advisory published Nov 24, 2025Updated Dec 1, 2025

Immediate action

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

npm uninstall sufetch

What this malware does

The package sufetch was found to contain malicious code.

Any computer that has this package installed or running should be considered fully compromised. All secrets and keys stored on that computer should be rotated immediately from a different computer. The package should be removed, but as full control of the computer may have been given to an outside entity, there is no guarantee that removing the package will remove all malicious software resulting from installing it.

This package was compromised by the Sha1-Hulud: The Second Coming NPM worm. The malicious payload steals tokens and credentials and publishes them to GitHub. The worm will propogate itself to NPM packages the user owns and establish persistence is a GitHub action. The package may also destroy the user's home directory.
