It would be a fun experiment to create a network probe executable that exfiltrates results back to you, and then push it to Microsoft in this way. I wonder how secure their test environment could be if it has Internet access...

I'd imagine the app is run in a DMZ and the internet FW blocks typical malware behavior once detected. After all the whole point of running it is to find if the executable is going to do these types of things so they'd be prepared.
