x64驱动程序中的钩子ZwTerminateProcess(没有SSDT)

Question

我发现并阅读了这个问题,但我没有找到我的答案SSDT挂钩替代x64系统

我想保护我的申请免受其他程序的终止.在32位版本的Windows中我使用了SSDT hooking挂钩ZwTerminateProcess或ZwOpenProcess.我现在要将程序升级为64位版本的Windows.不幸的是在64位窗口中我们不能使用SSDThook(因为Patch Guard(KPP)),请注意我不想在这种情况下绕过PG并且我只使用内核模式挂钩.例如,我不希望我的程序通过以下代码开始终止(偶数):

NTSTATUS drvTerminateProcess( ULONG ulProcessID )
{
    NTSTATUS          ntStatus = STATUS_SUCCESS;
    HANDLE            hProcess;
    OBJECT_ATTRIBUTES ObjectAttributes;
    CLIENT_ID         ClientId;

    DbgPrint( "drvTerminateProcess( %u )", ulProcessID );

    InitializeObjectAttributes( &ObjectAttributes, NULL, OBJ_INHERIT, NULL, NULL ); 

    ClientId.UniqueProcess = (HANDLE)ulProcessID;
    ClientId.UniqueThread  = NULL;

    __try
    {
        ntStatus = ZwOpenProcess( &hProcess, PROCESS_ALL_ACCESS, &ObjectAttributes, &ClientId );
        if( NT_SUCCESS(ntStatus) )
        {
            ntStatus = ZwTerminateProcess( hProcess, 0 );
            if( !NT_SUCCESS(ntStatus) )
                DbgPrint( "ZwTerminateProcess failed with status : %08X\n", ntStatus );

            ZwClose( hProcess );
        }
        else
            DbgPrint( "ZwOpenProcess failed with status : %08X\n", ntStatus );
    }
    __except( EXCEPTION_EXECUTE_HANDLER )
    {
        ntStatus = STATUS_UNSUCCESSFUL;
        DbgPrint( "Exception caught in drvTerminateProcess()" );
    }

    return ntStatus;
}

为了完成这项工作,我使用了以下函数(NewZwOpenProcess)并用ZwOpenProcess SSDT中的原始替换它,但在x64窗口中我不知道该怎么做:(:

NTSTATUS NewZwOpenProcess(
        OUT PHANDLE ProcessHandle,
        IN ACCESS_MASK DesiredAccess,
        IN POBJECT_ATTRIBUTES ObjectAttributes,
        IN PCLIENT_ID ClientId OPTIONAL)
{
        HANDLE ProcessId;

    __try 
    {
            ProcessId = ClientId->UniqueProcess;
    }
    __except(EXCEPTION_EXECUTE_HANDLER)
    {
       return STATUS_INVALID_PARAMETER;
    }

   if (ProcessId == (HANDLE)11) //Check if the PID matches our protected process PID (My programm)
    {
     return STATUS_ACCESS_DENIED; 
    }
  else 
    return OldZwOpenProcess(ProcessHandle, DesiredAccess,ObjectAttributes, ClientId);
}

任何的想法 ？？
