Which versions of tailwind-toolkit are malicious?

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

How do I remediate tailwind-toolkit if I installed it?

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

If tailwind-toolkit 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.

Is tailwind-toolkit part of a known attack campaign?

Yes — tailwind-toolkit is associated with the IN-MAL-2026-017750 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-toolkit across my projects, lockfiles, and CI pipelines?

Scan your lockfiles (package-lock.json, pnpm-lock.yaml, yarn.lock, requirements.txt, poetry.lock, etc.) and build artifacts for tailwind-toolkit (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-toolkit across your stack and pipelines.

Malicious package

tailwind-toolkitnpm

tailwind-toolkit is a confirmed malicious npm package (MAL-2026-14038) that steals credentials and exfiltrates sensitive data (malicious version 1.3.2). Do not install it — remove it immediately and rotate any exposed credentials.

Immediate action

Remove the package, then rotate any secrets the build/runtime could reach.

npm uninstall tailwind-toolkit

What this malware does

The package presents itself as a Tailwind CSS plugin, but its default export (which runs when users register it in tailwind.config) issues an HTTPS request to a hardcoded bare-IP endpoint at 31.97.137.157:45000/icons/109 and passes the response body's credits field into new Function(require, module, exports,...) for execution in the installer's Node process. The destination URL is assembled from split variables and disguised with CDN/icon vocabulary (an unused iconDomain map referencing cloudflare/fastly/akamai, a bearrtoken: "logo" header, a response field named credits), while the actual host is an unrelated bare IP on a non-standard port. The package also declares dependencies on @primno/dpapi (Windows DPAPI credential decryption), better-sqlite3/sqlite3 (browser cookie and Login Data databases), and node-machine-id, indicating the retrieved payload is a browser-credential stealer. The remote host and executed bytes are fully attacker-controlled and unrelated to the advertised Tailwind CSS purpose.

Find it
Scan your lockfiles (package-lock.json, pnpm-lock.yaml, yarn.lock, requirements.txt, poetry.lock, etc.) and build artifacts for tailwind-toolkit (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-toolkit across your stack and pipelines.
If you installed it — respond

Did it already run?
If tailwind-toolkit 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-toolkit 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.
