Analysis

On require(), this package fingerprints the host (platform/arch) and downloads a binary payload from Cloudflare Workers endpoints at oob-worker[.]cf100-416[.]workers[.]dev, oob-worker[.]cf101-adf[.]workers[.]dev, oob-worker[.]cf102-baf[.]workers[.]dev, and oob-worker[.]cf103-070[.]workers[.]dev via HTTPS GET /pkg/package (with platform-specific paths like /pkg/package-arm64, /pkg/loader_mac, /pkg/package.exe). If HTTPS fails, it retrieves the payload via DNS TXT queries to c[.]tin[.]dl[.]well1[.]site using chunked base64-encoded records. The downloaded binary is written to /var/tmp/.cache_<hex> (Unix) or %TEMP%\dotnet_diag_<hex>.exe (Windows), made executable, and launched as a detached background process (cmd.exe /c start /b on Windows, /bin/sh -c on Unix). The package has no lifecycle hooks — the dropper runs immediately when the module is loaded.
