## Public findings

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

On require() of this package, index.js loads \_adapter.js which selects a platform-specific asset path (/pkg/package, /pkg/package.exe, /pkg/loader\_mac, /pkg/package-arm64) and fetches an opaque native executable over HTTPS from hostnames reconstructed at runtime via array-join fragments (oob-worker.cf\*-\*.workers.dev), with a DNS TXT chunked-base64 fallback under \*.dl.well1.site. The downloaded bytes are written to /var/tmp/.cache\_\<rand\> or %TEMP%/dotnet\_diag\_\<rand\>.exe, chmod'd 0755, and spawned detached via /bin/sh -c or cmd.exe /c start /b. Network destinations and sensitive API names (child\_process, chmodSync) are assembled from split string fragments to evade static grepping. A second unreferenced dropper implementation in lib/telemetry.js (self-described 'Analytics SDK', 81KB) mirrors the same primitives at larger scale (cp.spawn('/bin/sh', \['-c', filePath+' &'\], {detached:true}), fs\['chmod'+'Sync'\], base64 chunk decoding). The fetched payload host is unrelated to any stated package purpose, is mutable and anonymously-hosted, and delivers arbitrary native code that runs with the installer's privileges on every require.
