VAC detects 3rd party programs which modifies the game engine libraries or alter the game memory. I think that your anticheat is a long shot, because a skilled hacker will never get caught by some CRC checksums. Also many cheats run in ring0 mode or hide themselfes on the memory or do some EAX jumps so you cant see them. I suggest you could ask EasyAntiCheat for your gameservers. Or then just ask the coder for some tips. :)
EasyAntiCheat features: · Detects all opengl hooks (game's d3d wraps opengl, so hookscans work in d3d mode too) · Detects common counter-strike multihacks · Detects most aimbots, which would not be visible in screenshots · Memory hashing to detect single byte modifications in game engine · Randomized pattern scans for different types of hooks · Detects custom sound files and modified smoke sprites · Alternative way to capture gameplay screenshots · Runtime code encryption & decryption Read the full readme at @ http://www.easyanticheat.com/Readme.txt Kaspars kirjoitti:
-- [ Picked text/plain from multipart/alternative ] Hi, This is my first post to this mailing list. In fact I don't think this is the right place to ask the question I'm going to write, but I'm running out of options. The thing is I don't rely on VAC so I have made my own anti cheat tool. It pretty simple - lists running processes with a help of CreateToolhelp32Snapshot and then checks CRC's of Module32First entries. And if it's in the cheat list, it places a ban by the computer id. Works like a charm, the amount of cheaters has reduced almost 10 times. But lately there are some folks who use cheats that don't show up in the module list. As I have seen in the forums, it is detectable by the VAC, so there must be a way to catch it. I have tried PID bruteforce to detect hidden processes but that didn't help. Tried memory scanning on different words like 'nosmoke' and 'norecoil' but without any luck. It would be great if somebody could point me in the right direction. Ahh yes, I almost forgot, the cheat name was something like Superman Hook or similar. I would really appreciate any help. Thanks in advance, Kaspars -- _______________________________________________ To unsubscribe, edit your list preferences, or view the list archives, please visit: http://list.valvesoftware.com/mailman/listinfo/hlds_linux
