# MAL-2026-14190: Malicious code in tailwind-utility-kit (npm)


- **Type:** Malicious package

## What is MAL-2026-14190?

MAL-2026-14190 is a malicious package in tailwind-utility-kit, published on 19 Aug 2026. 

### Official description

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.

## What should I do about MAL-2026-14190?

Remove the package from your dependencies and lockfiles, then rotate any secrets on machines where it was installed.
