OpenSSF/OSV advisory MAL-2026-17310 confirms this npm version as malicious. npm package tailwind-forms-kit@0.5.1 impersonates the @tailwindcss/forms plugin: the package.json name field is ' tailwind-forms-kit' (with a leading space), the README mirrors tailwindlabs/tailwindcss-forms, and the repository field points at the legitimate tailwindlabs/tailwindcss-forms repo. The shipped src/index.js (the package's main entry) is not a Tailwind plugin. It is a single-line obfuscator.io-obfuscated...

## Public findings

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

npm package tailwind-forms-kit@0.5.1 impersonates the @tailwindcss/forms plugin: the package.json name field is ' tailwind-forms-kit' (with a leading space), the README mirrors tailwindlabs/tailwindcss-forms, and the repository field points at the legitimate tailwindlabs/tailwindcss-forms repo. The shipped src/index.js (the package's main entry) is not a Tailwind plugin. It is a single-line obfuscator.io-obfuscated loader (string array \_0x18ab with 303 entries, rotate/shift IIFE, decoder \_0x35ba, hex-named variables) that at require() time imports node:http, node:https, node:zlib, and spawn from node:child\_process. It reassembles at runtime a hardcoded Ethereum sender address (0xa322E5f39aDC2490EfD311D3080e6f0121063e1a) and a list of public Ethereum RPC endpoints and an Etherscan-style indexer URL (publicnode.com, 1rpc.io, drpc.org, blockscout) from string-array indices, queries the indexer for that sender's transaction list ('?module=ac...on=txlist&address=...'), reconstructs a payload from the returned on-chain transaction data, and hands the reconstructed bytes to node:child\_process spawn / dynamic execution via global slots (\_t\_u, \_t\_s, \_H, \_H2). This is the EtherHiding blockchain-hosted-C2 pattern: whoever controls the sender address controls arbitrary code executed on any host that installs or requires the package, with no version pin, no hash verification, and blockchain-data transport chosen to evade domain and URL blocklists. The Tailwind branding, copied README, and misleading repository URL are cover for the loader.
