Little Question About RestoreCode

Are RestoreCode able restore own hooks? i mean if i hook ExitProcess. HookApi('kernel32.dll', 'ExitProcess', @InterceptExitProcess, @TrampolineExitProcess); procedure InterceptExitProcess(uExitCode: UINT); stdcall; begin ShowMessage('InterceptExitProcess'); //TrampolineExitProcess(uExitCode); end; A...

Re: About hooks

That's not a solution, it's a hack that will never work 100% and even create greater probability for process instability. If you can set a hook in usermode using usermode code so can the next process, or in this case, remove yours. Only proven method for truly blocking the opening or duplicating of...

Re: About hooks

iconic is right, as usual. If you insist on trying your best in user mode, I'd suggest that you hook NtProtectVirtualMemory and disallow modification of your API hook's memory pages. But it's easy enough to bypass such a hook, so it's really only one level more secure, but easy to bypass. Cat and m...

Re: About hooks

What does AreThisProcessProtected() look like? If it's just checking the process ID that Windows shows you in Task Manager, Process Explorer etc. then your code can easily be bypassed, even by the higher level OpenProcess() API from kernel32. Many aren't aware of this however you can open *any* pro...

Hello, I have a question, we did a dll who hook some apis like: HookApi('ntdll.dll', 'ZwOpenProcess', @InterceptZwOpenProcess, @TrampolineZwOpenProcess); function InterceptZwOpenProcess(ProcessHandle: PHANDLE; DesiredAccess: ACCESS_MASK; ObjectAttributes: POBJECT_ATTRIBUTES; ClientId: PCLIENT_ID): N...

Re: How RestoreCode works

I understand, so it's better hook these apis and just call a RestoreCode(@TrampolineHookedFunction) right?

another question, how about manual map injection on MCH? it on user mode.

Re: About modules

FreeLibrary is the right API. But you're only supposed to unload modules you've loaded yourself. Or modules that you know you can unload without causing trouble. If you unload a module and it crashes, then obviously you can't do that. I've tried unload a module injected by a external process, so it...

Re: About modules

Well, as I said, don't call "Modules" multiple times. There may be other things like that in your code. Of course even if your code is perfect, madKernel may still be slower because it encapulates everything into nice interfaces. But it shouldn't be that much of an overhead - unless you'r...
