## Public findings

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

dist/index.js contains an obfuscated top-level async IIFE that executes on import. It queries Ethereum JSON-RPC endpoints (eth.drpc.org, eth.publicnode.com, ethereum-rpc.publicnode.com, and an Etherscan-like API) for the most recent transaction from a hardcoded marker address (0xa322E5f39aDC2490Ef6f0121063e358050D311D3080e), parses the transaction's \`to\` field into two IPv4 addresses, HTTP-fetches XOR-encrypted payloads from \`http://\<ip\>/0x/ls\` and \`http://\<ip\>:443/0x/cl\`, XOR-decrypts them, then executes the resulting JavaScript via \`eval(...)\` and a detached \`spawn('node', \['-e', \<decrypted\>\], {detached:true})\`. The entire loader is packed with obfuscator.io-style transforms (hex \`\_0x\` identifiers, rotating string array \`\_0x240a\`, control-flow flattening) that conceal the network-fetch-and-exec chain behind benign-looking exports. On-chain C2 makes the exfil/RCE destination mutable and takedown-resistant; the payload contents are opaque and attacker-controlled.
