Hello
Im kinda new to API hooking but i need to do one thing.
I would like to prevent any other application than my own to hook into specific process (OpenProcess, ReadProcessMemory, WriteProcessMemory and so on). Whats the best way to do this? I hope i explained it clearly enough. Thanks in advance
What language are you using?
You may want to further explain/justify why this is needed which may result in more replies
Well if you hook into your own program and neglect any CallNextHookEx calls you could prevent other programs from monitoring your events. One problem is that Windows made it easy to inject dll code into unmanaged code (all hacks etc. are made around this principle), so it is never possible to prevent this from happening.
Unless there is a way to routinely check if your managed code has been changed (hash compare check?) which I doubt, there is simply no way. Software protectors like Punkbuster, Gameshield, etc. exist for a reason... :)
Im going to use either Visual Basic or Visual C#.
Software protectors are not good enough for me since i need to gain info about several computers connected via p2p gaming tool. The way to do that is to protect each computer locally and send its status to other computers.
