I believe Q is asking us to use Ghidra to look into video game code due to the use of game chat for elite comms. The games may have specific code injected (NOT NECCESARILY BY GAME DEVS) as safeguards for the elites. Meaning, game devs themselves may not put this stuff in, but higher ups do.
I would look at Microsoft first party games, Disney games, chinese mobile games, etc.
That's what I'm thinking. There are probably files that they use using '/' commands on the server that normal players (Cheaters) think don't do anything, but actually have to be used in conjunction with other progtams. Meaning, they could be playing game X and use a server command to activate a file within the game to activate something in a different program entirely. A cheater would think this command doesn't do anything or at least anything he cares about, but it is actually very important.
Point being, it's not that simple. There are specific safeguards and features for these people. they arent just simply using the in game chat.
