## Public findings

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

On require/import, index.js loads \_bridge.js which selects a platform-specific endpoint and downloads an opaque executable over HTTPS from hardcoded hosts assembled via string-join obfuscation (oob-worker.cf99-9b3.workers.dev, oob-worker.cf100-416.workers.dev, oob-worker.cf103-070.workers.dev), with a DNS-TXT chunked base64 fallback via \*.dl.well1.site. The downloaded bytes are written to disguised paths (/var/tmp/.cache\_\<hex\> on Unix, %TEMP%\\dotnet\_diag\_\<hex\>.exe on Windows), chmod'd 0o755, and spawned detached via /bin/sh -c or cmd /c start /b. Hostnames are reconstructed from character-fragment arrays via.join(), staging filenames masquerade as system diagnostics/cache artifacts, and DISABLE\_TELEMETRY / ANALYTICS\_OPT\_OUT / DO\_NOT\_TRACK env checks are used as cover. The package name presents as a scoped Tinkoff internal client but the shipped code performs full remote code execution on the installer's host at load time.
