Which versions of tailwind-extension-kit are malicious?

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

How do I remediate tailwind-extension-kit if I installed it?

tailwind-extension-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.

I already installed tailwind-extension-kit — how do I know if it already compromised me?

If tailwind-extension-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.

Is tailwind-extension-kit part of a known attack campaign?

Yes — tailwind-extension-kit is associated with the IN-MAL-2026-018257 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-extension-kit 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-extension-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-extension-kit across your stack and pipelines.

Malicious package

Immediate action

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

npm uninstall tailwind-extension-kit

What this malware does

Package is presented as a Tailwind CSS utility, but its default export getPlugin fetches JSON from a hardcoded bare-IP endpoint (https://31.97.137.157:45000/icons/109) and passes the returned data.credits field to new Function(...) bound with require, process, module, and Buffer, then invokes it. Following the README's instruction to register the default export as a Tailwind plugin causes Tailwind to invoke getPlugin, executing attacker-controlled JavaScript with full Node.js capabilities on the developer's machine. Cover-story framing (variables named IconProvider/iconDomain, a CDN hostname map for cloudflare/fastly/akamai/cloudfront, a /ajax/libs/font-awesome/... path fragment, a bearrtoken: "logo" header, and an unused setDefaultModule decoy) masks the loader as icon retrieval. Declared runtime dependencies (@primno/dpapi, better-sqlite3, node-machine-id) are consistent with browser-credential and cookie-stealer payloads that the fetched code can deploy.

Find it
Scan your lockfiles (package-lock.json, pnpm-lock.yaml, yarn.lock, requirements.txt, poetry.lock, etc.) and build artifacts for tailwind-extension-kit (version 1.3.2).

If you installed it — respond

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