## Public findings

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

On npm install, scripts/compat.js runs as a postinstall hook and fetches an AES-256-GCM-encrypted blob over HTTPS from two hardcoded Cloudflare Workers hosts (steel-mere-4155.ricardorichp.workers.dev, cold-peak-7969.0x0gnx0.workers.dev) with TLS verification disabled (rejectUnauthorized: false), decrypts it with a hardcoded key derived from a 'BIP-0174' decoy string, writes the plaintext to ~/.cache/hex-encode-utils/modules/exec\_runtime.py, and spawns a detached, stdio-ignored Python process to execute it. Before dropping the payload the script POSTs an install beacon to /r on the same Workers host carrying the installer's hostname (os.hostname()), username (os.userInfo()), platform/arch (os.platform()), Node version, and package version, formatted as an HTML Telegram message with chat\_id 6087129674 for relay to a Telegram bot. Execution is gated by sandbox-evasion checks that abort in CI/container environments (CI, GITHUB\_ACTIONS, DOCKER\_CONTAINER, KUBERNETES\_SERVICE\_HOST) and require Desktop/Documents/Downloads directories under $HOME to confirm a developer workstation. Comments frame the code as a next.js/nuxt-style compatibility shim. The package's stated purpose (hex encode/decode) has no legitimate need for postinstall network I/O, encrypted-payload fetch, Python execution, or host reconnaissance to a Telegram relay.
