The decoded body is packed with an obfuscator.io-style string-array dispatcher (`_0x355e` / `_0x12f0` with shuffling) that hides all string literals, and it dynamically resolves `node:http`, `node:https`, `node:zlib`, and `child_process.spawn` via `createRequire(import.meta.url)`. At runtime it assembles an Ethereum RPC endpoint list from `process.env.ETH_RPC_URL` plus hardcoded providers including `*.publicnode.com` and `h.drpc.org`, together with an indexer URL and a hardcoded `SENDER` Ethereum address, and issues `eth_blockNumber` and block-range requests — the shape of an on-chain wallet-monitoring / drainer relay embedded in a CSS-only utility. A Tailwind scrollbar-hiding plugin has no legitimate need to eval a base64 blob, spawn child processes, open network sockets, or scan Ethereum blocks on import.\n\n## Source: ghsa-malware (419e7970b5bc0bd5afe8a044ba0c64352a634818d5a96f850657ff8506af5677)\nAny computer that has this package installed or running should be considered fully compromised.
