HookApi例子

Windows 7 64位 HookApi例子

 

　　本程序HOOK的API是DispatchMessageA和DispatchMessageW。在HOOK的方法内会还原ESP，调用user32.DispathMessage(A或W)之后再修改ESP，实现的功能是记录消息的详细日志，记录哪个窗口处理过哪些消息。

　　1、新建一个win32 console项目，取名为DoInjection，新建一个DoInjectionMain.h，代码如下：

?

1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 23

BOOL SetPrivilege(LPCTSTR lpszPrivilege, BOOL bEnablePrivilege); BOOL IsVistaOrLater(); BOOL InjectProcess(); BOOL InjectCreateProcess(); void HookGetMessage(); BOOL InjectCreateThread(HANDLE hProcess, LPTHREAD_START_ROUTINE pThreadProc, LPVOID pRemoteBuf); HANDLE MsicCreateRemoteThread(HANDLE hProcess,LPTHREAD_START_ROUTINE lpStartAddress,LPVOIDlpParameter);   typedef void*(__stdcall*LPFN_KernelBaseGetGlobalData)(void); typedef DWORD (WINAPI *PFNTCREATETHREADEX) (     PHANDLE                 ThreadHandle,       ACCESS_MASK             DesiredAccess,      LPVOID                  ObjectAttributes,       HANDLE                  ProcessHandle,      LPTHREAD_START_ROUTINE  lpStartAddress,     LPVOID                  lpParameter,        BOOL                    CreateSuspended,        DWORD                   dwStackSize,        DWORD                   dw1,     DWORD                   dw2,     LPVOID                  Unknown );

　　2、新建一个DoInjectionMain.c(不是CPP)，代码如下：

?
