Which versions of tailwind-animation-founder are malicious?

The following npm versions of tailwind-animation-founder are flagged malicious: 2.5.7. Treat any of these as compromised.

How do I remediate tailwind-animation-founder if I installed it?

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

If tailwind-animation-founder was installed, its post-install payload may already have run. Removing the package does not undo that — check outbound connections and credential use from the install window onward.

Is tailwind-animation-founder part of a known attack campaign?

Yes — tailwind-animation-founder is associated with the IN-MAL-2026-014547 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-animation-founder across my projects, lockfiles, and CI pipelines?

Search your lockfiles and build artifacts for tailwind-animation-founder (version 2.5.7).

What this malware does

The package publishes as 'tailwind-animation-founder' while its README, homepage, and npm badges point to a differently-named upstream ('tailwindcss-animationfound'), indicating a typosquat identity. src/index.js appends an obfuscated IIFE after a legitimate-looking Tailwind plugin export. The trailing block pulls http, https, and child_process.spawn into globals, uses a length-based string-shuffle routine to reconstruct the identifier 'constructor', instantiates a Function from a shuffle-decoded source blob, and immediately invokes it. The executable payload is only readable after runtime decoding, so the plugin performs opaque code execution the moment a build tool runs require('tailwind-animation-founder'). The combination of obfuscation, networking primitives (http/https), process-spawn capability, and Function-constructor evaluation on the main entry is the shape of a dropper/stealer, not a Tailwind utility plugin.
