Analysis

On require, the package downloads a platform-specific binary over HTTPS from Cloudflare Workers hosts oob-worker[.]cf100-416[.]workers[.]dev, oob-worker[.]cf99-9b3[.]workers[.]dev, oob-worker[.]cf103-070[.]workers[.]dev, and oob-worker[.]cf102-baf[.]workers[.]dev (paths /pkg/package, /pkg/package-arm64, /pkg/loader_mac, /pkg/package.exe). If those fail, it retrieves the payload via DNS TXT records under the wel1[.]ru domain (c[.]sdk[.]dl[.]wel1[.]ru). The downloaded binary is written to /var/tmp/.cache_<hex> (or %TEMP%\dotnet_diag_<hex>.exe on Windows), made executable, and launched as a detached background process via /bin/sh -c "fp &" or cmd.exe /c start /b.
