## Public findings

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

On require of the package's main entry, lib/utils.min.js queries Ethereum RPC endpoints (eth.blockscout.com/api, 1rpc.io/eth, eth.drpc.org, ethereum-rpc.publicnode.com, eth-mainnet.public.blastapi.io) for the latest outbound transaction from the hardcoded address 0xa322E5f3D311D3080e6f0121063e9aDC2490Ef1a, parses two IPv4 C2 hosts from the transaction's \`to\` field, fetches an XOR-encoded JavaScript payload over plain HTTP at \`http://\<ip\>:443/0x/cls\`, decodes it, and executes it via both \`eval\` and a detached \`spawn('node', \['-e', payload\])\`. Sensitive identifiers (\`http\`, \`https\`, \`child\_process\`, \`zlib\`, \`url\`, URLs, HTTP methods, header names, the attacker address) are hidden behind \\uXXXX unicode escapes, and the response body and \`x-payload-b64\` header are XOR-decoded with a per-URL key before execution. The package is presented as a Tailwind CSS plugin and has no legitimate need for Ethereum RPC access, IP derivation from on-chain data, or execution of remotely fetched code.
