- **Product-default install policy:** Block
- **Firewall policy:** Matched malicious
- **Public report status:** Published

- **Analysis source:** OSV Malicious Advisory (OpenSSF/OSV)

Trusted malware advisory MAL-2026-17524 identifies this version as malicious. Firewall keeps the version blocked under its trusted-intelligence policy. An AI recommendation to allow or warn does not override that advisory.

OpenSSF/OSV advisory MAL-2026-17524 confirms this npm version as malicious. The package name tailwindcss-forms-styles mimics the legitimate @tailwindcss/forms plugin, and its src/index.js copies that plugin's code verbatim as cover. Above the cover code, a top-level IIFE joins a ~140-element base64 string array, atob()-decodes it, and eval()s the result...

## Public findings

### 1. High: Osv Malicious Advisory
- **Category:** External Intel
- **Confidence:** 100.0%

The package name tailwindcss-forms-styles mimics the legitimate @tailwindcss/forms plugin, and its src/index.js copies that plugin's code verbatim as cover. Above the cover code, a top-level IIFE joins a ~140-element base64 string array, atob()-decodes it, and eval()s the result. The decoded loader queries public Ethereum RPC/Blockscout endpoints for the most recent transaction sent by hardcoded address 0xa322E5f3D311D3080e6f0121063e9aDC2490Ef1a, parses two IPv4 addresses out of the transaction recipient field, downloads an XOR-encoded JavaScript payload from staging URLs of the form http://\<ip\>:443/0x/cls and http://\<ip\>:443/0x/ls, and executes it via eval and a detached spawn('node', \['-e',...\]) child process. Because the IIFE runs at module load, any consumer that performs require('tailwindcss-forms-styles') triggers remote code execution on the installer, with the command-and-control endpoint resolved dynamically from the blockchain so the C2 can be rotated without changing the package.
