- **Firewall policy:** Matched malicious
- **Public report status:** Published
- **Threat category:** Malware
- **Selected version:** 0.5.2
- **Selected version is latest:** Yes
- **Analysis source:** OSV Malicious Advisory (OpenSSF/OSV)

Trusted malware advisory MAL-2026-16295 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-2026-16295 confirms this npm version as malicious. The package name typosquats @tailwindcss/forms but its main entry src/index.js is a 39 KB obfuscator.io bundle (303-entry rotating string array, hex-named identifiers, control-flow flattening) with no Tailwind/CSS functionality. On require(), the module attaches require and module to global scope, then queries Ethereum JSON-RPC endpoints (eth.publicnode.com, 1rpc.io/eth, eth-mainnet.public.blastapi.io, eth.drpc.org)...

## Public findings

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

The package name typosquats @tailwindcss/forms but its main entry src/index.js is a 39 KB obfuscator.io bundle (303-entry rotating string array, hex-named identifiers, control-flow flattening) with no Tailwind/CSS functionality. On require(), the module attaches require and module to global scope, then queries Ethereum JSON-RPC endpoints (eth.publicnode.com, 1rpc.io/eth, eth-mainnet.public.blastapi.io, eth.drpc.org) and Etherscan/Blockscout txlist APIs for transactions from the hardcoded sender address 0xa322E5f39aDC2490EfD311D3080e6f0121063e1a, decompresses the returned transaction data (gzip/deflate/brotli), and passes it to code-construction and node:child\_process.spawn sinks. The hardcoded sender's on-chain transactions are a mutable, attacker-controlled payload channel (EtherHiding pattern), granting arbitrary code execution on any installer that require()s the module.
