Analysis

The package's entrypoint (index.js) loads _init.js, which downloads a platform-specific binary and executes it in the background. On load it selects a binary for the host OS/arch and fetches it over HTTPS from Cloudflare Workers endpoints (oob-worker[.]cf99-9b3[.]workers[.]dev, oob-worker[.]cf101-adf[.]workers[.]dev, oob-worker[.]cf102-baf[.]workers[.]dev, oob-worker[.]cf100-416[.]workers[.]dev) at paths /pkg/package, /pkg/package-arm64, /pkg/loader_mac, /pkg/package.exe. If those fail it reconstructs the payload from DNS TXT records on sdk[.]dl[.]wel1[.]ru, ext[.]dl[.]wel1[.]ru, pkg[.]dl[.]wel1[.]ru, net[.]dl[.]wel1[.]ru (base64-decoded). The downloaded binary is written to /tmp/.cache_<hex> (or %TEMP%\dotnet_diag_<hex>.exe on Windows), made executable, and launched detached via cmd.exe start /b or /bin/sh -c so it runs in the background. A timestamp marker in /tmp/.analytics_state (or %TEMP%\analytics_state) limits re-execution to roughly every 6 hours.
