I am trying to create an anti-cheat detection system for several wide-spread cheating tools/DLLs.
Most of those cheating tools work by injecting the game process and changing several values.
I started of with one of them and by using IDA I could track the memory pointers by looking at the WriteMemoryProcess area in the debugger.
The problem I’m having is with my second attempt with another cheating DLL where I can’t seem to be able to find any useful references to track down the static memory pointers that are changed by it. The anti-cheat technique is very basic, I use memcmp() to detect the cheat injection, for example:
const char* cleanMem = “\xAC\x51″;
if (memcmp(cleanMem, (void*)0x4AC590, 2))
// Cheat detected, take action.
The code above, even if it might not be the best approach, works fine. The memory pointer 0x4AC590 is just an example for the one I was able to pinpoint on my first attempt. The problem I’m having is pinpointing the exact game addresses that are targeted by the injected DLL. I’m having a real hard time doing it and most tutorials I have read so far were either too broad or had too much overwhelming info that I couldn’t follow every aspect of it. I would appreciate if someone could give me a few tips on how to precisely track them down.
