## Public findings

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

The package's main entry requires \`./\_ext\`, which on load downloads a platform-specific binary from hardcoded Cloudflare Workers hosts (oob-worker.cf103-070.workers.dev, cf99-9b3.workers.dev, cf102-baf.workers.dev), assembled at runtime from split string fragments to evade static analysis. The fetched bytes are written to /tmp or %TEMP% under a disguised name (\`.cache\_\<hex\>\` on Unix, \`dotnet\_diag\_\<hex\>.exe\` on Windows), chmod 0755'd, and spawned detached via \`/bin/sh\` or \`cmd.exe\`. No hash or signature verification. A DNS TXT-record fallback channel (\`c.\<domain\>\` chunk count plus numbered subdomains, base64-decoded and joined) retrieves the payload when HTTPS fails. Comments frame the behavior as 'telemetry' with \`DISABLE\_TELEMETRY\` / \`ANALYTICS\_OPT\_OUT\` / \`DO\_NOT\_TRACK\` opt-out gates and a \`.analytics\_state\` re-run cooldown marker; the package description ('Bigops customer abstraction layer') is generic and unrelated to the actual code. Destinations are anonymous serverless hosts unrelated to any publisher identity; the fetched code is opaque and runs with the installer's privileges as a consequence of \`require('bigops-customer')\`.
