Forum: Anti-Cheat Development

Hey my names Adam, I have been lurking quite a bit around these forums trying to gain a better knowledge into what goes into developing an anti-cheat. But I think I need a bit of help getting started, I know basic C++ etc. But I am lost from the start, the thing I am trying to create would be...

OK so can someone send me or show me code of dll that can protect the parent procces from injection. I want to inject that dll in some process and that dll should protect the process. Does someone have this kind of dll ? Thanks.

If you hit someone before the xhair reaches them, what exactly does that mean? Hitting someone before my xhair got to them would only be possible through the use of an aimbot right? Would this be a good indication of an aimbot if i saw someone else doing it while spectating them? Or can it...

Basically, I found a way to do compile-time string encryption using macros. Usage is like so: EncryptString("String here", name_of_string); Then the macro will allocate space for name_of_string using a character array.

Well I would like to know how to go about hiding a process, like gameguard does. So if you were to try attach the process using something like CE, you wouldn't be able to find it in the process list. Also how would I go about detecting if any new memory has been allocated, and what are some...

Hey, I'm currently thinking about the ways an AC could work... My idea is, that I want to collect ideas and then write example codes (just for excercise) So far I've come up with these facts: Anti-Cheat: Hook LoadLibrary, GetProcAddress, VQuery, what else? Do (of course) Screenshots...

Does such a thing exist? Why don't games stop sending player locs if they aren't reasonably visible, or perform sanity checks on player view angles? There's a million other checks that could be made. To me this is just basic stuff. If you record a player's input, with and without hacks, it would be...

Certain cheats works by patching the memory using WriteProcessMemory. In hl2 you can do it with like sv_cheats 1 and other cvars. How would I go about detecting this without false positives? Hash the modules .data section and check it against the real? ~Acid

I am making a small anti-cheat tool and I have a problem, I can easily detect JMP hooks (and the likes) by simply checking a hash of a the .text section of the module. How would I go about detecting a VMT hook (or other hooks like it), I would love some pointers on where to look and what to look...

#include <windows.h> #include <intrin.h> DWORD_PTR CODE_BEGIN = 0x00401000; DWORD_PTR CODE_END = CODE_BEGIN + 0x95E; DWORD_PTR INV_CODE_BEGIN = ~CODE_BEGIN; DWORD_PTR INV_CODE_END = ~CODE_END; DWORD_PTR DATA_BEGIN = 0x00403000;

I am looking to hire an experienced cheat detection designer for Valve based games. They will also need to be capable of making a deamon as well. PM me or aim me at : cashmoney32008

To mask what code is being executed, I had the idea of having threads which modify eachother interchangeably. For example: #include <windows.h> #pragma comment( linker, "/SUBSYSTEM:WINDOWS" ) #pragma comment( linker, "/ENTRY:main" ) DWORD CurrentThread = 1;
