If this package is installed
Remove it, treat the machine (or CI runner) as compromised, and rotate every secret, token and key it could access — from a different, clean machine.

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.
