Immediate action
Remove the package, then rotate any secrets the build/runtime could reach.
npm uninstall @lui-ui/lui-tailwindcss

What this malware does

The package @lui-ui/lui-tailwindcss 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.

Detection & response playbook

Credential / info stealer

  1. Find it

    Search your lockfiles and build artifacts for @lui-ui/lui-tailwindcss (version 0.1.2).

  2. If you installed it — respond

    @lui-ui/lui-tailwindcss 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.

  3. Did it already run?

    If @lui-ui/lui-tailwindcss 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.

Frequently asked questions

No. @lui-ui/lui-tailwindcss on npm has been identified as a malicious package (version 0.1.2 flagged). It should be removed immediately — do not install or keep it in your dependency tree.
