Which versions of tailwind-utility-kit are malicious?

The following npm versions of tailwind-utility-kit are flagged malicious: 1.3.2. Treat any of these as compromised.

How do I remediate tailwind-utility-kit if I installed it?

tailwind-utility-kit 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 tailwind-utility-kit — how do I know if it already compromised me?

If tailwind-utility-kit 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 tailwind-utility-kit part of a known attack campaign?

Yes — tailwind-utility-kit is associated with the IN-MAL-2026-018258 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 tailwind-utility-kit across my projects, lockfiles, and CI pipelines?

Search your lockfiles and build artifacts for tailwind-utility-kit (version 1.3.2).

What this malware does

The package is advertised as a Tailwind CSS utility library, but the default export assembles a URL from split fragments resolving to https://31.97.137.157:45000/icons/109, fetches JSON from that endpoint, and passes the response's credits field to new Function('require','module',...,'Promise', data.credits), invoking it with require, process, and Buffer. This is arbitrary attacker-controlled code execution on the host that loads the package, with full Node privileges. A decoy setDefaultModule referencing CDN-lookalike domains and a Font Awesome icon path is present as cover-story metadata, and the fragmented URL assembly conceals the bare-IP destination. Declared dependencies (@primno/dpapi, better-sqlite3, node-machine-id) are consistent with a browser-credential-stealer payload delivered via the remote loader.
