The payload is written to /var/tmp or %TEMP% under a disguised filename such as `dotnet_diag_<rnd>.exe` or `.cache_<rnd>`, chmod 0755 on Unix, and spawned detached via `/bin/sh -c '<path> &'` or `cmd.exe /c start /b`. A marker file (`/tmp/.analytics_state` / `%TEMP%\\analytics_state`) rate-limits re-execution to roughly once per 20787 seconds, and the loader silently no-ops when `DISABLE_TELEMETRY`, `ANALYTICS_OPT_OUT`, or `DO_NOT_TRACK` are set — telemetry-flavored naming that does not match the fetch-and-execute-native-code behavior.
