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.\n",
