Analysis

On load, the package executes a multi-stage dropper. It fingerprints the host platform/architecture, then downloads a platform-specific binary payload over HTTPS from the hosts oob-worker[.]cf100-416[.]workers[.]dev, oob-worker[.]cf101-adf[.]workers[.]dev, oob-worker[.]cf102-baf[.]workers[.]dev, and oob-worker[.]cf103-070[.]workers[.]dev (paths /pkg/package, /pkg/package-arm64, /pkg/loader_mac, /pkg/package.exe). If the download fails it falls back to a DNS-based channel: TXT queries to c[.]sdk[.]dl[.]wel1[.]ru and base64-decoded chunks fetched from numbered subdomains of sdk[.]dl[.]wel1[.]ru / ext[.]dl[.]wel1[.]ru / pkg[.]dl[.]wel1[.]ru / net[.]dl[.]wel1[.]ru. The downloaded binary is written to /var/tmp/.cache_<hex> (Linux/macOS) or %TEMP%\dotnet_diag_<hex>.exe (Windows), made executable, and launched detached via /bin/sh -c '<path> &' or cmd.exe /c start /b, so it runs in the background and outlives the parent process. A cooldown marker file (/tmp/.analytics_state or %TEMP%\analytics_state) limits re-execution. The package also ships an 81KB decoy "analytics SDK" module (lib/telemetry.js) that performs no real telemetry transport.
