Malicious code in tailwind-utility-kit (npm)

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.
