- **Verdict:** Malicious
- **Product-default install policy:** Block
- **Firewall policy:** Matched malicious
- **Public report status:** Published
- **Threat category:** Malware
- **Selected version:** 0.5.1

Trusted malware advisory MAL-2026-15925 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-2026-15925 confirms this npm version as malicious. The package's main module src/index.js begins with eval(atob("...")) that decodes ~30 KB of obfuscated JavaScript before the genuine plugin code. The decoded loader imports http/https/zlib and child\_process.spawn, hoists require and module onto globals (global\['r'\], global\['m'\]) to escape the module sandbox, and evaluates payloads received from remote endpoints...

## Public findings

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

The package's main module src/index.js begins with eval(atob("...")) that decodes ~30 KB of obfuscated JavaScript before the genuine plugin code. The decoded loader imports http/https/zlib and child\_process.spawn, hoists require and module onto globals (global\['r'\], global\['m'\]) to escape the module sandbox, and evaluates payloads received from remote endpoints. The loader hardcodes an Ethereum sender address (assembled from fragments including '0xa322E5f3','D311D3080e','6f0121063e') and a set of RPC endpoints on public Ethereum nodes (drpc.org, publicnode.com, blockscout, ethereum-rpc) plus an Etherscan-style indexer queried with 'module=account&action=txlist&address=...&sort=desc'. It polls eth\_blockNumber / eth\_getBlockByNumber / eth\_getTransactionCount to monitor the on-chain address and retrieves payloads carried in x-payload-b64 headers, decompressed through zlib createGunzip/createInflate and executed. The loader fires on any require('tailwind-contact-forms'). The package name mimics @tailwindcss/forms and its package.json repository field points at https://github.com/tailwindlabs/tailwindcss-forms; the obfuscated loader is prepended above a verbatim copy of the legitimate @tailwindcss/forms plugin source so the package appears to work normally after infection.
