post-css-transfer @0.0.1

Summary

post-css-transfer is a typosquat of postcss whose main entry lib/postcss.js has an obfuscated IIFE appended after the legitimate module code. On require/import, the appended block resolves a command-and-control IP by reading transactions of Ethereum address 0xa322E5f3D311D3080e6f0121063e9aDC2490Ef1a via public Ethereum RPC endpoints and the eth.blockscout.com API, decodes two IPv4 addresses from the transaction recipient bytes, fetches an XOR-encrypted payload over HTTP from those hosts (delivered in an x-payload-b64 header), and executes the decrypted payload via eval() and a detached node -e child process. Network, execution, and identifier primitives (http, child_process, spawn, the Ethereum address, method and header names) are written as \uXXXX escapes and hidden behind ~1KB of whitespace padding after module.exports = postcss; to evade casual review.
