在Win7下很多XP的驱动都不适用了！前几个月研究了一下盛*大游戏的泡泡*堂的Hack*Shield驱动保护发现Hook了十多个内核函数，Ring 3和 Ring 0的双重保护
现在暂时发现钩住了一下函数
hook NtOpenProcess
hook NtReadVirtualMemory
hook NtWriteVirtualMemory
Hook NtClose
Hook NtProtectVirtualMemory
Hook NtGetContextThread
其中HOOK NtGetContextThread中用了两个钩子，恢复起来有些麻烦，但还是给恢复了
Ring 3层的程序通过DeviceIoControl传递游戏进程ID给驱动，然后驱动就执行相关的动作！现在给出部分关键的代码！
Ring 3层：// 安装驱动的线程函数
UINT __cdecl CDriverProtectDlg::InstallDriverThread(LPVOID pParam)
{
CDriverProtectDlg* pDlg = NULL;
pDlg = (CDriverProtectDlg*)pParam;
pDlg->UpdateData(TRUE);
if (pDlg->strPath.IsEmpty())
{
AfxMessageBox(L"请选择驱动路径！");
return 0;
}
if (pDlg->strrGamePath.IsEmpty())
{
AfxMessageBox(L"请选择游戏路径！");
return 0;
}
if (!pDlg->LoadNTDriver(L"HelloDDK",pDlg->strPath.GetBuffer()))
{
pDlg->UnloadNTDriver(L"HelloDDK");
pDlg->LoadNTDriver(L"HelloDDK",pDlg->strPath.GetBuffer());
}
HANDLE hDevice =
::CreateFileW(L"\\\\.\\HelloDDK",
GENERIC_READ | GENERIC_WRITE,
0, // share mode none
NULL, // no security
OPEN_EXISTING,
FILE_ATTRIBUTE_NORMAL,
NULL ); // no template
if (hDevice == INVALID_HANDLE_VALUE)
{
pDlg->m_DriverINFORMATION.SetWindowTextW(L"打开驱动错误！");
return 1;
}
DWORD Pid = pDlg->TransferProcessID(pDlg->strrGamePath.GetBuffer());
int a = (int)Pid;
UCHAR* InputBuffer = new UCHAR[a];
UCHAR* OutputBuffer= new UCHAR[a];
BOOL bRet;
DWORD dwOutput;
//输入缓冲区作为输入，输出缓冲区作为输出
bRet = DeviceIoControl(hDevice, IOCTL_TEST1, InputBuffer, a, OutputBuffer, a, &dwOutput, NULL);
if (bRet)
{
pDlg->m_DriverINFORMATION.SetWindowTextW(L"开启保护成功！");
}
CloseHandle(hDevice);
delete []InputBuffer;
delete []OutputBuffer;
//AfxEndThread(0);
ResumeThread(pDlg->ProcessMainThread);
pDlg = NULL;
return 0;
}
UINT __cdecl CDriverProtectDlg::UnInstallDriverThread(LPVOID pParam)

driver.rar 为Ring 0层的驱动文件及调试用的PDB文件
然后这些代码就可以让CE正常打开进程扫描，修改游戏内存数据了！OD附加功能还在开发中。

本人顺便录制了一个教程帮助讲解代码：
