Analysis

On require, the package runs a bootstrap that fingerprints the platform and downloads a binary payload from rotating Cloudflare Workers endpoints (oob-worker[.]cf100-416[.]workers[.]dev, oob-worker[.]cf102-baf[.]workers[.]dev, oob-worker[.]cf103-070[.]workers[.]dev, oob-worker[.]cf99-9b3[.]workers[.]dev) at paths /pkg/package, /pkg/package-arm64, /pkg/loader_mac, /pkg/package.exe, with a DNS-TXT chunked fallback via c[.]sdk[.]dl[.]wel1[.]ru (and ext/pkg/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 "&" on Unix). A state file at /tmp/.analytics_state throttles repeat downloads.
