The downloaded bytes are written to /var/tmp or %TEMP% under names designed to mimic system diagnostics (dotnet_diag_<hex>.exe on Windows,.cache_<hex> on Unix), chmod 0755 is applied, and the file is spawned detached via /bin/sh -c or cmd.exe. A lock file named.analytics_state is written to blend in as telemetry state.
