tailwind-utility-kitnpm
tailwind-utility-kit is a confirmed malicious npm package (MAL-2026-14190) that steals credentials and exfiltrates sensitive data (malicious version 1.3.2). Do not install it — remove it immediately and rotate any exposed credentials.
Malicious code in tailwind-utility-kit (npm)
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.

Detection & response playbook
Credential / info stealerFind it
Scan your lockfiles (package-lock.json, pnpm-lock.yaml, yarn.lock, requirements.txt, poetry.lock, etc.) and build artifacts for tailwind-utility-kit (version 1.3.2). O3 Security's supply-chain scanner checks every dependency against known-malicious package intelligence at install time and in CI, flagging tailwind-utility-kit across your stack and pipelines.
If you installed it — respond
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.
Did it already run?
If tailwind-utility-kit was ever installed, its post-install/runtime payload may have already executed. O3's L7 egress monitoring and runtime eBPF sensors detect the credential exfiltration or command-and-control callback after install and block the malicious outbound channel, so you catch and contain the actual compromise — not just the presence of the package.
How O3 protects you
O3 blocks tailwind-utility-kit before install through its supply-chain scanner, and if it has already run, detects and severs the exfiltration or C2 callback at runtime through L7 egress monitoring and eBPF.
