The fetched bytes are written to /var/tmp or %TEMP% under cover-story names (analytics_state, dotnet_diag_*.exe,.cache_*), chmod 0755 on Unix, and spawned detached via /bin/sh -c or cmd.exe /c start /b. The package advertises itself as a design system but ships no design-system code path that would need to fetch and execute native binaries, and the destination hosts, filenames, and delivery channel are all obfuscated.
