# MAL-2026-15905: Malicious code in tailwindcss-3d-styles (npm)


- **Type:** Malicious package
- **Package:** `tailwindcss-3d-styles` (npm)
- **Published:** 4 Sep 2026

## What is MAL-2026-15905?

MAL-2026-15905 is a malicious package in tailwindcss-3d-styles, published on 4 Sep 2026. 

### Official description

The package's main entry point fetches a JavaScript file from http://23.27.245.100:3000/index.js over plain HTTP at require time, writes the response to./inout.js in the current working directory, and require()s the resulting file — causing arbitrary code from that host to execute in the Node process of any consumer importing this package. The remaining code is a copy of the legitimate `tailwindcss-3d` library (per the manifest's repository/homepage), and the published name `tailwindcss-3d-styles` differs from the upstream `tailwindcss-3d`, using the upstream library as cover for the appended dropper.

## What should I do about MAL-2026-15905?

Remove the package from your dependencies and lockfiles, then rotate any secrets on machines where it was installed.
