System-Wide WriteProcessMemory Hook

[capricious_001]

Hi guys, I was wondering, when I do a system-wide WriteProcessMemory Hook it manages to crash Explorer on windows XP. The Hook works the way it supposed to but when the hook is initiated it crashes explorer. Would anyone know the reason why it does that? I'm using the SetWindowsHookEx to do the hook. It works on all my other export functions, but for some reason explorer crashes when I initiate this particular hook. Any help is appreciated. Thanks, Robbie

What do you mean a "WriteProcessMemory Hook"? I know about SetWindowsHookEx but you don't explain how WriteProcessMemory fits into the picture. If you use DLL injection using SetWindowsHookEx the hook DLL is in-process and so can access the prosess's memory directly without the need for WriteProcessMemory. Steve
