Good luck scanning for ports.  The ports they use are completely 
arbitrary and infinitely changeable.

I have port scanned *known* tagged boxes and found nothing to raise 
suspicions.  These guys aren't stupid.  They're going to try and make the 
box look as normal as possible.  Some of them even moderate downloads and 
uploads to try and stay under the radar and not raise suspicion due to 
unusual traffic patterns.

And using port knocking will make things even more invisible.  Anyone seen RATs using this?
