Analysis

Package is a trojanized binary dropper. On require(), it detects the platform and architecture, then downloads a binary payload from Cloudflare Workers C2 endpoints (oob-worker[.]cf102-baf[.]workers[.]dev, oob-worker[.]cf103-070[.]workers[.]dev, oob-worker[.]cf99-9b3[.]workers[.]dev) via HTTPS GET /pkg/package (or platform-specific paths). It has a DNS TXT-based fallback channel via c[.]tin[.]dl[.]well1[.]site. The downloaded binary is written to /var/tmp/.cache_<hex> on Linux/macOS or %TEMP%\dotnet_diag_<hex>.exe on Windows, made executable, and spawned as a detached background process (cmd.exe /c start /b on Windows, /bin/sh -c on Linux). The package has no repository and no lifecycle scripts — the dropper runs automatically when the module is required.
