Summary: Malicious code in tailwindcss-hide-scrollbar (npm)

Details: Source: amazon-inspector (ac906893a6ea1562025bfa35bf4f1998cfd745619f21c4dc3880aa386dc3cfe1) dist/index.js exports a small tailwind scrollbar-hide plugin followed by a trailing eval(atob('<~32KB obfuscator.io payload>')) that executes on every require()/import of the package. The decoded payload pulls in http, https, zlib and child_process.spawn (with require('child_proc'+'ess') split-string obfuscation and an obfuscator.io string-array dispatcher) and contains hardcoded Ethereum JSON-RPC method names (eth_getBlockByNumber, eth_blockNumber), etherscan-style transaction listing paths (?module=account&action=...&startblock=0&endblock=99999999), a process.env.ETH_RPC_URL read, and hardcoded RPC/explorer hosts under drpc.org, publicnode.com, blockscout.com and blast-api.io. A CSS utility plugin has no legitimate need for network I/O, spawned child processes, or dynamic evaluation of an obfuscated blob. The package name inverts the word order of the established tailwind-scrollbar-hide plugin, consistent with a typosquat carrier for the loader.

All secrets and keys stored on that computer should be rotated immediately from a different computer. The package should be removed, but as full control of the computer may have been given to an outside entity, there is no guarantee that removing the package will remove all malicious software resulting from installing it.
