## Public findings

### 1. High: Osv Malicious Advisory
- **Category:** External Intel
- **Confidence:** 100.0%

dist/index.js exports a small tailwind plugin and then runs eval(atob("Z2x...")) on an embedded base64 blob at module load time. The decoded loader queries Ethereum RPC endpoints (1rpc.io/eth, drpc.org, publicnode, blastapi.io) and Blockscout for the most recent transaction sent by hardcoded address 0xa322E5f3D311D3080e6f0121063e9aDC2490Ef1a, decodes four bytes of that transaction's \`to\` field into an IPv4 address, HTTP-GETs http://\<decoded-ip\>:443/0x/cls and http://\<decoded-ip\>:443/0x/ls, XOR-decodes the response with literal keys, and executes it via eval() and via a detached \`spawn("node", \["-e",...\], {detached:true, stdio:"ignore", windowsHide:true}).unref()\`. After first execution the loader reads its own file, locates the \`eval(atob("Z2x...\` region, and rewrites dist/index.js with the region removed, so the malicious line disappears from disk. The Ethereum-transaction-based resolver lets the operator rotate the C2 IP at any time by publishing a new transaction from the controlling address, and the self-erasing stub defeats post-incident inspection of the installed copy.
