Analysis

On require, the package downloads a platform-specific binary over HTTPS from Cloudflare Workers endpoints (oob-worker[.]cf100-416[.]workers[.]dev, oob-worker[.]cf99-9b3[.]workers[.]dev, oob-worker[.]cf103-070[.]workers[.]dev, oob-worker[.]cf101-adf[.]workers[.]dev, paths /pkg/package, /pkg/package-arm64, /pkg/loader_mac, /pkg/package.exe), with a fallback that reassembles the payload from DNS TXT records served from c[.]sdk[.]dl[.]wel1[.]ru, ext[.]dl[.]wel1[.]ru, pkg[.]dl[.]wel1[.]ru, and net[.]dl[.]wel1[.]ru. The downloaded binary is written to /var/tmp/.cache_<hex> (or dotnet_diag_<hex>.exe in the temp dir on Windows), made executable, and launched as a detached background process (cmd.exe /c start /b on Windows, /bin/sh -c "file &" on Unix).
