• 暴力大法好

    通过暴力枚举进行隐藏进程的恢复（利用进程ID全为4的倍数）

    EnumProcessByForce

    Ring3层程序：

    首先要进行提权：

     1 BOOL EnableDebugPrivilege()   //Debug 
 2 {
 3 
 4     HANDLE hToken = NULL;   
 5     TOKEN_PRIVILEGES TokenPrivilege;
 6     LUID uID;
 7 
 8 
 9     //打开权限令牌
10     if (!OpenProcessToken(GetCurrentProcess(),TOKEN_ADJUST_PRIVILEGES|TOKEN_QUERY,&hToken))
11     {
12         return FALSE;
13     }
14 
15     if (!LookupPrivilegeValue(NULL,SE_DEBUG_NAME,&uID))
16     {
17     
18         CloseHandle(hToken);
19         hToken = NULL;
20         return FALSE;
21     }
22 
23 
24     TokenPrivilege.PrivilegeCount = 1;
25     TokenPrivilege.Privileges[0].Attributes = SE_PRIVILEGE_ENABLED;
26     TokenPrivilege.Privileges[0].Luid = uID;
27 
28 
29     //在这里我们进行调整权限
30     if (!AdjustTokenPrivileges(hToken,false,&TokenPrivilege,sizeof(TOKEN_PRIVILEGES),NULL,NULL))
31     {
32         CloseHandle(hToken);
33         hToken = NULL;
34         return  FALSE;
35     }
36 
37     CloseHandle(hToken);
38     return TRUE;
39 
40 }
    提权函数

    并且将UAC执行级别调到　　requireAdministrator (/level='requireAdministrator')

    在链接器中可以找到

    在EnumProcessByForce函数中暴力枚举 调用OpenProcess检测进程ID是否有效

     1 VOID EnumProcessByForce()
 2 {
 3     int i = 0;
 4     HANDLE hProcess = NULL;
 5     DWORD  dwReturn = 0;
 6 
 7     char   szProcessImageName[MAX] = {0};
 8     for (i=0;i<10000000;i+=4)
 9     {
10         hProcess = OpenProcess(PROCESS_QUERY_INFORMATION,FALSE,i);
11 
12         if (hProcess==NULL)
13         {
14             continue;
15         }
16 
17         else
18         {
19             //向驱动发送请求
20             if(SendIoControl(&i,sizeof(ULONG32),szProcessImageName,&dwReturn)==TRUE)
21             {
22                 szProcessImageName[dwReturn] = '';
23                 cout<<"进程ID: "<<i<<" "<<szProcessImageName<<endl;
24                 memset(szProcessImageName,0,MAX);
25             }
26         }
27     }
28 }
    EnumProcessByForce

    Ring3与Ring0数据交互两种方法：

    1.IoControl码 Ring3--->Ring0 BufferIO Ring0---->Ring3(BufferIO UserIO OtherIO) Io管理器 Irp请求针对设备对象

    2.ReadFile WriteFile       Ring3--->Ring0(BufferIO  UserIO  OtherIO)   Ring0---->Ring3(BufferIO UserIO OtherIO)

    这里使用第一种方法

     1 BOOL  SendIoControl(int* InputData,ULONG InputSize,char* OutputData,DWORD* dwReturn)
 2 {
 3     //打开设备
 4 
 5     HANDLE hDevice = NULL;
 6 
 7     BOOL   bOk = FALSE;
 8 
 9     hDevice = CreateFile(L"\\.\EnumProcessByForceLinkName",GENERIC_READ | GENERIC_WRITE,
10         FILE_SHARE_READ | FILE_SHARE_WRITE,
11         NULL,
12         OPEN_EXISTING,
13         FILE_ATTRIBUTE_NORMAL,
14         NULL);
15 
16     if (hDevice==INVALID_HANDLE_VALUE)
17     {
18         return FALSE;
19     }
20 
21 
22     bOk = DeviceIoControl(hDevice,CTL_GETPROCESSIMAGNAMEBYID,
23         InputData,
24         InputSize,
25         OutputData,
26         MAX,
27         dwReturn,
28         NULL);
29 
30 
31     if (bOk==FALSE)
32     {
33         CloseHandle(hDevice);
34         hDevice = NULL;
35 
36         return FALSE;
37     }
38     CloseHandle(hDevice);
39     hDevice = NULL;
40     return TRUE;
41 }
    SendIoControl
    BOOL WINAPI DeviceIoControl(
    _In_ HANDLE hDevice,
    _In_ DWORD dwIoControlCode,
    _In_opt_ LPVOID lpInBuffer,
    _In_ DWORD nInBufferSize,
    _Out_opt_ LPVOID lpOutBuffer,
    _In_ DWORD nOutBufferSize,
    _Out_opt_ LPDWORD lpBytesReturned,
    _Inout_opt_ LPOVERLAPPED lpOverlapped);
     
    hDevice Long，设备句柄
    dwIoControlCode Long，应用程序调用驱动程序的控制命令，就是IOCTL_XXX IOCTLs。
    lpInBuffer Any，应用程序传递给驱动程序的数据缓冲区地址。
    nInBufferSize Long，应用程序传递给驱动程序的数据缓冲区大小，字节数。
    lpOutBuffer Any，驱动程序返回给应用程序的数据缓冲区地址。
    nOutBufferSize Long，驱动程序返回给应用程序的数据缓冲区大小，字节数。
    lpBytesReturned Long，驱动程序实际返回给应用程序的数据字节数地址。
    lpOverlapped OVERLAPPED，这个结构用于重叠操作。针对同步操作，请用ByVal As Long传递零值

    发送控制代码直接到指定的设备驱动程序，使相应的移动设备以执行相应的操作
