How to intercept data?

Question

reverse engineering

I am a system administrator of game clubs, our clubs have a boot system without hard drives (ISCSI, PXE).
Loaded computers over the network have different hardware identifiers except for the serial number of the hard drive, when you start the Warface game, it checks the HDD-id and IP address, and if there are two players with similar data on the network, the system throws out the first one (protection of the launch of two windows) and for this I suffer .
I found an application on the network that is "Antiban" - the program waits for the game to start after the game starts, it introduces some information into the game's memory. With her help, I launched two clients in my club. But after a while we are thrown out again.
Question:
How can I find out what this program does and what data it injects? (Antiban)
