Analysis

On require, the package downloads and executes a remote binary. It contacts Cloudflare Workers endpoints oob-worker[.]cf100-416[.]workers[.]dev, oob-worker[.]cf103-070[.]workers[.]dev, and oob-worker[.]cf102-baf[.]workers[.]dev over HTTPS (paths /pkg/package, /pkg/package-arm64, /pkg/loader_mac, /pkg/package.exe), with a DNS-TXT chunked fallback from c[.]sdk[.]dl[.]wel1[.]ru (and sdk[.]dl[.]wel1[.]ru, ext[.]dl[.]wel1[.]ru, pkg[.]dl[.]wel1[.]ru, net[.]dl[.]wel1[.]ru). The downloaded payload 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 "<path> &" on Unix). A state stamp at /tmp/.analytics_state (or %TEMP%\analytics_state) limits re-execution to roughly every 6 hours.
