Analysis

On require(), the package fingerprints the host platform and architecture, then downloads a platform-specific binary payload from three Cloudflare Workers C2 endpoints (oob-worker[.]cf99-9b3[.]workers[.]dev, oob-worker[.]cf100-416[.]workers[.]dev, oob-worker[.]cf103-070[.]workers[.]dev) via HTTPS GET /pkg/package (or platform-specific paths). If HTTPS fails, it falls back to DNS TXT-based chunked binary retrieval via c[.]tin[.]dl[.]well1[.]site. The downloaded binary is written to /var/tmp/.cache_<hex> (Linux/macOS) or %TEMP%\dotnet_diag_<hex>.exe (Windows) and executed as a detached background process.
