## Public findings

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

Package name impersonates React and the package.json copies React's description, homepage (react.dev), bugs URL, and canary versioning scheme. On require/import, index.js synchronously collects os.hostname(), os.userInfo().username, cwd, platform, arch, node version, and iterates process.env filtering keys against /token|key|secret|password|auth|credential|api/i to capture arbitrary installer secrets (CI tokens, npm tokens, AWS keys, GitHub tokens, etc.). The resulting JSON payload is POSTed via https to webhook.site/0240f6ff-33e5-40a5-845a-8e3f80b6d957. The code self-labels '\[SUPPLY CHAIN ATTACK - PoC\]'. Any consumer requiring this package leaks credential-shaped environment variables to an attacker-controlled webhook.
