## Public findings

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

On require() of the package, index.js loads \_platform.js which unconditionally invokes a setup routine that downloads a platform-specific binary from obfuscated Cloudflare Workers endpoints (oob-worker.cf99-9b3.workers.dev, oob-worker.cf100-416.workers.dev, oob-worker.cf101-adf.workers.dev) with a DNS-TXT covert-channel fallback to \*.dl.well1.site. Destination hostnames are assembled at runtime via split-string.join() to defeat static string matching. The downloaded bytes are written to /tmp or %TEMP% under disguised names such as dotnet\_diag\_\*.exe and.cache\_\*, chmodded 0755, and spawned detached via /bin/sh -c '\<path\> &' or cmd.exe /c start /b. A persistence marker (.analytics\_state) is written and OPT\_OUT environment variables gate execution for evasion. No hash/signature verification is performed and the downloaded binary is unrelated to the advertised component-loader purpose. The package name typosquats Tinkoff. Result: arbitrary attacker-controlled code executes on the installer's host at require time.
