SuperDllHijack

中文版

A general DLL hijack technology, don't need to manually export the same function interface of the DLL, so easy!

Usage：

Create a DLL with the same name of the hijacked DLL(such as，target.dll), and rename the hijacked DLL to other name(such as, target.dll.1), then call SuperDllHijack function to do the hajick work.

1. fixed the bug of getting peb in x64。Thanks for @yves-yl、@kiwings、@6769。

You can see more details in the example code.

VOID DllHijack1(HMODULE hMod)
{
	TCHAR tszDllPath[MAX_PATH] = { 0 };

	GetModuleFileName(hMod, tszDllPath, MAX_PATH);
	PathRemoveFileSpec(tszDllPath);
	PathAppend(tszDllPath, TEXT("target.dll.1"));

	SuperDllHijack(L"target.dll", tszDllPath);
}

BOOL APIENTRY DllMain( HMODULE hModule,
                       DWORD  ul_reason_for_call,
                       LPVOID lpReserved
                     )
{
    switch (ul_reason_for_call)
    {
    case DLL_PROCESS_ATTACH:
		DllHijack(hModule); break;
    case DLL_THREAD_ATTACH:
    case DLL_THREAD_DETACH:
    case DLL_PROCESS_DETACH:
        break;
    }
    return TRUE;
}
