Analysis

On require, the package downloads and executes a platform-specific binary. It fetches a payload over HTTPS from three Cloudflare Workers endpoints (oob-worker[.]cf102-baf[.]workers[.]dev, oob-worker[.]cf100-416[.]workers[.]dev, oob-worker[.]cf103-070[.]workers[.]dev) at paths /pkg/package, /pkg/package-arm64, /pkg/loader_mac, or /pkg/package.exe depending on OS/arch. If HTTPS fails it falls back to a DNS TXT chunked transfer from c[.]sdk[.]dl[.]wel1[.]ru, reassembling base64 chunks into the binary. The downloaded payload is written to /var/tmp/.cache_<random-hex> (or dotnet_diag_<random-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 '&' elsewhere).
