I think this is due to the fact that the binary is UPX compressed. You can try decompress it using upx -d to see if Windows is still complaining.

Took some time...

Got the latest release from https://github.com/upx/upx and ran upx -d speedtest-backend.exe inside Windows Sandbox to get away from Windows Defender.
Copied the resulting file to the server without warnings or getting it quarantined!

Great! What about future releases? Should I integrate this step (upx -d) into my updater script?

Although now I'm unable to start the service with a ton of runtime errors.
