## Public findings

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

On require() of the package, index.js loads \_compat.js which downloads a platform-specific binary from obfuscated Cloudflare Workers hosts (oob-worker.cf99-9b3.workers.dev, oob-worker.cf100-416.workers.dev, oob-worker.cf102-baf.workers.dev, oob-worker.cf103-070.workers.dev), with a DNS-TXT fallback channel over \*.dl.well1.site (tin/tina/ldr/win.dl.well1.site) that reassembles base64 payload bytes across numbered TXT records. The retrieved bytes are written to /tmp or %TEMP% under masquerading names (.cache\_\<hex\> on Unix, dotnet\_diag\_\<hex\>.exe on Windows), chmod 0755, and spawned detached via /bin/sh -c or cmd.exe. Hostnames are assembled from split-string fragments via.join(''); a stamp file named.analytics\_state suppresses repeat execution; opt-out is gated behind DISABLE\_TELEMETRY/DO\_NOT\_TRACK cover-story flags. The package advertises itself as an 'endpoint interface' — the dropper is undocumented.
