枚举消息钩子
简单粘贴点百度的解释，科普下消息钩子：
钩子是WINDOWS中消息处理机制的一个要点，通过安装各种钩子，应用程序能够设置相应的子例程来监视系统里的消息传递以及在这些消息到达目标窗口程序之前处理它们。 钩子的种类很多，每种钩子可以截获并处理相应的消息，如键盘钩子可以截获键盘消息，鼠标钩子可以截获鼠标消息，外壳钩子可以截获启动和关闭应用程序的消息，日志钩子可以监视和记录输入事件。
钩子的类型：
（1） 键盘钩子和低级键盘钩子可以监视各种键盘消息。
（2） 鼠标钩子和低级鼠标钩子可以监视各种鼠标消息。
（3） 外壳钩子可以监视各种 Shell 事件消息。比如启动和关闭应用程序。
（4） 日志钩子可以记录从系统消息队列中取出的各种事件消息。
（5） 窗口过程钩子监视所有从系统消息队列发往目标窗口的消息。
此外，还有一些特定事件的钩子提供给我们使用，不一一列举。
常用的 Hook 类型：
1、WH_CALLWNDPROC 和 WH_CALLWNDPROCRET Hooks
WH_CALLWNDPROC 和 WH_CALLWNDPROCRET Hooks 使你可以监视发送到窗口过程的消息。系统在消息发送到接
收窗口过程之前调用 WH_CALLWNDPROC Hook 子程，并且在窗口过程处理完消息之后调用 WH_CALLWNDPRO
CRET Hook 子程。WH_CALLWNDPROCRET Hook 传递指针到 CWPRETSTRUCT 结构，再传递到 Hook 子程。
CWPRETSTRUCT 结构包含了来自处理消息的窗口过程的返回值，同样也包括了与这个消息关联的消息参数。
2、WH_CBT Hook
在以下事件之前，系统都会调用 WH_CBT Hook 子程，这些事件包括：
1. 激活，建立，销毁，最小化，最大化，移动，改变尺寸等窗口事件；
2. 完成系统指令；
3. 来自系统消息队列中的移动鼠标，键盘事件；
4. 设置输入焦点事件；
5. 同步系统消息队列事件。
Hook 子程的返回值确定系统是否允许或者防止这些操作中的一个。
3、WH_DEBUG Hook
在系统调用系统中与其他 Hook 关联的 Hook 子程之前，系统会调用 WH_DEBUG Hook 子程。你可以使用这个
Hook 来决定是否允许系统调用与其他 Hook 关联的 Hook 子程。
4、WH_FOREGROUNDIDLE Hook
当应用程序的前台线程处于空闲状态时，可以使用 WH_FOREGROUNDIDLE Hook 执行低优先级的任务。当应用
程序的前台线程大概要变成空闲状态时，系统就会调用 WH_FOREGROUNDIDLE Hook 子程。
5、WH_GETMESSAGE Hook
应用程序使用 WH_GETMESSAGE Hook 来监视从 GetMessage 或 PeekMessage 函数返回的消息。你可以使用
WH_GETMESSAGE Hook 去监视鼠标和键盘输入，以及其他发送到消息队列中的消息。
6、WH_JOURNALPLAYBACK Hook
WH_JOURNALPLAYBACK Hook 使应用程序可以插入消息到系统消息队列。可以使用这个 Hook 回放通过使用WH_JOURNALRECORD Hook 记录下来的连续的鼠标和键盘事件。只要 WH_JOURNALPLAYBACK Hook 已经安装，正常的鼠标和键盘事件就是无效的。WH_JOURNALPLAYBACK Hook 是全局 Hook，它不能象线程特定 Hook 一样
使用。WH_JOURNALPLAYBACK Hook 返回超时值，这个值告诉系统在处理来自回放 Hook 当前消息之前需要等待多长时间（毫秒）。这就使 Hook 可以控制实时事件的回放。WH_JOURNALPLAYBACK 是 system-wide localhooks，它们不会被注射到任何进程地址空间。（估计按键精灵是用这个 hook 做的）
7、WH_JOURNALRECORD Hook
WH_JOURNALRECORD Hook 用来监视和记录输入事件。典型的，可以使用这个 Hook 记录连续的鼠标和键盘事件，然后通过使用 WH_JOURNALPLAYBACK Hook 来回放。WH_JOURNALRECORD Hook 是全局 Hook，它不能象线程特定 Hook 一样使用。WH_JOURNALRECORD 是 system-wide local hooks，它们不会被注射到任何进程地址空间。
枚举内核消息钩子
枚举消息钩子的总体思路。首先获得名为 gSharedInfo的全局变量的地址（此变量在 user32.dll 里被导出），它的值其实是一个内核结构体 win32k!tagsharedinfo 的地址：
接下来 tagSERVERINFO.cHandleEntries 的值，这个值记录了当前消息钩子的数目（记为 count）：
然后读取 gSharedInfo+8 的值，获得 aheList 的值（记为 phe），此值为 首个
HANDLEENTRY 结构体的地址：
接下来，从 phe 首地址开始，获得【count-1】个的 HANDLEENTRY 结构体的指针，HANDLEENTRY.phead 记录的值指向一个 HEAD 结构体，HEAD 结构体才记录了
每个消息钩子的具体信息。当然也不是每个 HANDLEENTRY 都是消息钩子，只有当
HANDLEENTRY.bType 为 5 时才是消息钩子。
然后就是把资料上的那个写的比较精简的函数拿出来，枚举消息钩子：
注意这个函数实在R3里面：
void EnumMsgHook()
{
int i=0;
UINT64 pgSharedInfo=0;
pgSharedInfo = (UINT64)GetProcAddress(GetModuleHandleA("user32.dll"), "gSharedInfo");
UINT64 phe = GetQWORD(pgSharedInfo+8);
UINT64 count = GetQWORD(GetQWORD(pgSharedInfo)+8);
HANDLEENTRY heStruct={0};
HOOK_INFO Hook={0};
for(i=0;i<count;i++)
{
memcpy(&heStruct,(PVOID)(phe + i*sizeof(HANDLEENTRY)),sizeof(HANDLEENTRY));
if(heStruct.bType==5)
{
RKM(heStruct.phead,&Hook,sizeof(HOOK_INFO));
printf("hHandle: 0x%llx\n",Hook.hHandle);
printf("iHookFlags: %s\n",GetHookFlagString(Hook.iHookFlags));
printf("iHookType: %s\n",GetHookType(Hook.iHookType));
printf("OffPfn: 0x%llx\n",Hook.OffPfn);
printf("ETHREAD: 0x%llx\n",GetQWORD((UINT64)(Hook.Win32Thread)));
printf("ProcessName: %s\n\n",GetPNbyET(GetQWORD((UINT64)(Hook.Win32Thread))));
}
}
}接下来是驱动部分代码，感觉里面的那些读写内存什么的写的比较归整（来源于资料，胡文亮），这里也整理下方便以后使用：
先是内存拷贝：
BOOLEAN VxkCopyMemory( PVOID pDestination, PVOID pSourceAddress, SIZE_T SizeOfCopy )
{PMDL pMdl = NULL;PVOID pSafeAddress = NULL;pMdl = IoAllocateMdl( pSourceAddress, (ULONG)SizeOfCopy, FALSE, FALSE, NULL );if( !pMdl ) return FALSE;__try{MmProbeAndLockPages( pMdl, KernelMode, IoReadAccess );}__except(EXCEPTION_EXECUTE_HANDLER){IoFreeMdl( pMdl );return FALSE;}pSafeAddress = MmGetSystemAddressForMdlSafe( pMdl, NormalPagePriority );if( !pSafeAddress ) return FALSE;RtlCopyMemory( pDestination, pSafeAddress, SizeOfCopy );MmUnlockPages( pMdl );IoFreeMdl( pMdl );return TRUE;
}
ULONG64 rwkm_adr=0, rwkm_len=0;然后是内存读写---R3
