## Public findings

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

The package advertises itself as a React Ethereum provider exporting EthereumProvider/useProvider/useSigner/useNetwork hooks, but the shipped main entry lib/index.js contains web3.js Subscriptions code plus a large obfuscated payload wrapped in a Function("ObbvO95", "...") constructor that is invoked at module load. The payload uses randomized hex-named identifiers, a signed-integer decode table, and a doubly-unicode-escaped string body to hide its behavior from static inspection. Any consumer that require('eth-react-provider') executes this opaque code in the installer's process. The src/index.js in the tarball contains the clean web3.js source without this payload, indicating the built artifact was tampered. The README/code mismatch (documented React hook API vs. actual web3.js Subscriptions plus loader) is consistent with a trojanized lookalike package rather than a broken release.
