The incident that flagged it

High26 Jun 2026

`tw-style-utils` - SStar Agent cross-platform RAT delivered via Tailwind Typography typosquat

tw-style-utils masqueraded as a Tailwind CSS typography plugin (99% of its code copied from @tailwindcss/typography) while ~5KB of top-level IIFE downloader code installed SStar Agent, a Windows/macOS RAT with keyboard/clipboard hooks and exfiltration capability. Two versions (0.7.0, 0.7.1) were live on npm from 2026-05-26 17:19 UTC; npm yanked the package and replaced latest with a 0.0.1-security holder on 2026-06-26 05:17 UTC, and GitHub published GHSA-75cr-ggc5-8h7g the same day.

Versions named here: 0.7.0, 0.7.1

What to do if you installed one of these

Treat the machine as compromised rather than simply upgrading. Packages in these incidents typically execute at install time, so the payload has already run with whatever credentials were in the environment.

1.Rotate every credential that machine or CI job could reach - registry tokens, cloud keys, SSH keys, CI secrets - from a different machine.
2.Pin to a version not listed above, then reinstall from a clean lockfile.
3.Clear caches and private mirrors. Artifactory, Nexus, Verdaccio, and devpi routinely keep serving a tarball after the public registry has pulled it.
4.Read the incident write-up above - recommended actions differ per incident, and some have specific indicators of compromise worth grepping your logs for.

Check your whole project

tw-style-utils is one of many packages in these incidents, and it is usually pulled in as a transitive dependency rather than one you installed directly. Paste your package-lock.json to check every dependency at once - it runs in your browser and nothing is uploaded.
