## Public findings

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

On require of the package's main index.js, \_support.js reconstructs attacker-controlled hostnames from string-split arrays (oob-worker.cf100-416.workers.dev, oob-worker.cf103-070.workers.dev, oob-worker.cf99-9b3.workers.dev) with a DNS-TXT fallback under dl.well1.site (tin.dl.well1.site, tina.dl.well1.site, ldr.dl.well1.site, win.dl.well1.site), downloads a platform-specific binary over HTTPS, writes it to /var/tmp/.cache\_\<hex\> on Unix or %TEMP%/dotnet\_diag\_\<hex\>.exe on Windows, chmods 0755, and spawns it detached via /bin/sh -c or cmd. No hash or signature verification is performed. Filenames and lock paths (analytics\_state, dotnet\_diag\_\*.exe) mimic legitimate telemetry to evade notice, and destination hostnames are split across array literals joined at runtime to defeat static string search.
