确定Windows和windows系统目录
有两个SDK函数可以完成该功能。GetWindowsDirectory和GetSystemDirectory，下例说明了如何使用这两个函数：
TCHAR szDir [MAX_PATH];
//Get the full path of the windows directory.
:: GetWindowsDirectory (szDir, MAX_PATH);
TRACE (“Windows directory %s\n”, szDir);
//Get the full path of the windows system directory.
:: GetSystemDirectory (szDir, MAX_PATH);
TRACE (“Windows system directory %s\n”, szDir);
让程序从CTRL+ATL+DEL消失
使用Win32 API函数RegisterServiceProcess这里我们使用了汇编。
#include <windows.h>
HINSTANCE hLibrary;
void *regproc;
void CADInit(void);
void HideApp(void);
void ShowApp(void);
void CADClean(void);
int WINAPI WinMain(HINSTANCE hInstance, HINSTANCE hPrevInstance, LPSTR lpCmdLine, int nCmdShow)
{
CADInit(); //加载 DLL 并创建一指向它指针
HideApp(); //隐藏程序
//ShowApp(); //显示程序
//其他处理或调用
CADClean(); //卸载 DLL
return 0; //retrun 0 因为没有进入消息循环
}
void CADInit(void)
{
//加载 kernel32.dll
hLibrary = LoadLibrary(“kernel32.dll”);
//获取函数RegisterServiceProcess的地址
regproc = GetProcAddress(hLibrary, “RegisterServiceProcess”);
}
void HideApp(void)
{
//实现程序的隐藏
__asm
{
push 1
push 0
call regproc
}
return;
}
void ShowApp(void)
{
//恢复状态
__asm
{
push 0
push 0
call regproc
}
return;
}
void CADClean(void)
{
//卸载 DLL
FreeLibrary(hLibrary);
return;
}
本程序在W2K和Win9x测试通过。
程序自杀(进程自己结束自己)
HMODULE module = GetModuleHandle(0);
CHAR buf[MAX_PATH];
GetModuleFileName(module, buf, sizeof buf);
CloseHandle(HANDLE(4));
__asm
{
lea eax, buf
push 0
push 0
push eax
push ExitProcess
push module
push DeleteFile
push UnmapViewOfFile
ret
}
return;
操作系统信息
//结构OSVERSIONINFO包含操作系统的版本信息
OSVERSIONINFO osvi;
CString winver,os;
osvi.dwOSVersionInfoSize=sizof(OSVERSIONINFO);
GetVersionEx(&osvi);
switch(osvi.dwPlatformId)
{
case 0:
os=”Win 3.X”;
break;
case 1:

break;
case 2:

}
隐藏你的鼠标
（注意：注销或重新启动就可以恢复）
一、建立一个单文档的应用程序框架
二、为隐藏主窗口，将OnCreate 删除。
并在App类里修改m_pMainWnd指向ShowWindow(SW_HIDE)
三、现在在mainframe的实现文件里添加如下内容：
POINT mp,cursorNew;
/////////////////////////////////////
// CMainFrame construction/destruction
UINT FMouse(LPVOID param)
{
int flag=0;
WINDOWPLACEMENT wp;///窗口位置
wp.length=sizeof(WINDOWPLACEMENT);
HWND hWnd;
char tmp[20];
RECT rt;
hWnd=GetDesktopWindow();////GetForegroundWindow();
GetWindowPlacement(hWnd,&wp);
GetWindowRect(hWnd,&rt);
GetWindowText(hWnd,tmp,20);
HDC dc=GetDC((HWND)param);
int iResult;
iResult=AfxMessageBox(“确实要隐藏吗？”,MB_OKCANCEL);
if(iResult==IDOK)
{
while(1)
{
hWnd=GetForegroundWindow();//GetDesktopWindow();
GetWindowRect(hWnd,&rt);
GetWindowText(hWnd,tmp,20);
GetWindowPlacement(hWnd,&wp);
GetCursorPos(&cursorNew);
while(1){
::mouse_event(MOUSEEVENTF_MOVE,cursorNew.x,cursorNew.y,0,0);
}
}
}
return 0;
}
在构造函数里启动线程CMainFrame::CMainFrame()
{
HWND hWnd=::GetParent(NULL);
GetCursorPos(&mp);
AfxBeginThread(FMouse,hWnd,0);
}
系统的定时关机
TOKEN_PRIVILEGES tkp;
HANDLE hToken;
if (!OpenProcessToken(GetCurrentProcess(),TOKEN_ADJUST_PRIVILEG ES | TOKEN_QUERY, &hToken))
{
MessageBox(“OpenProcessToken failed!”);
}
LookupPrivilegeValue(NULL, SE_SHUTDOWN_NAME,&tkp.Privileges[0].Luid); //获得本地机唯一的标识
tkp.PrivilegeCount = 1;
tkp.Privileges[0].Attributes = SE_PRIVILEGE_ENABLED;
AdjustTokenPrivileges(hToken, FALSE, &tkp, 0,(PTOKEN_PRIVILEGES) NULL, 0); //调整获得的权限
if (GetLastError() != ERROR_SUCCESS)
{
MessageBox(“AdjustTokenPrivileges enable failed!”);
}
fResult =InitiateSystemShutdown(
NULL, // 要关的计算机用户名,可在局域网网中关掉对方的机器，NULL表示关本机
“由于系统不稳定，WINDOWS将在上面的时间内关机，请做好保存工作!”, // 显示的消息
10, // 关机所需的时间
TRUE,
TRUE); //设为TRUE为重起，设为FALSE为关机
if(!fResult)
{
MessageBox(“InitiateSystemShutdown failed.”);
}
tkp.Privileges[0].Attributes = 0;
AdjustTokenPrivileges(hToken, FALSE, &tkp, 0,(PTOKEN_PRIVILEGES) NULL, 0);
if (GetLastError() != ERROR_SUCCESS)
{
MessageBox(“AdjustTokenPrivileges disable failed.”);
}
ExitWindowsEx(EWX_SHUTDOWN,0); //开始关机
程序只运行一个实例，并激活前一个实例
具体实现：
1、在程序初始化的时候 (InitInstance()) 枚举所有的窗口，查找本程序的实例是否存在
2、在主窗口初始化的时候在本窗口的属性列表中添加一个标记，以便程序查找.
部分关键代码
1、在App的InitInstance()中枚举所有窗口，查找本程序实例
HWND oldHWnd = NULL;
EnumWindows(EnumWndProc,(LPARAM)&oldHWnd); //枚举所有运行的窗口
if(oldHWnd != NULL)
{
AfxMessageBox(“本程序已经在运行了”);
::showWindow(oldHWnd,SW_SHOWNORMAL); //激活找到的前一个程序
::setForegroundWindow(oldHWnd); //把它设为前景窗口
return false; //退出本次运行
}
2、添加EnumWndProc窗口过程函数：//添加的标识只运行一次的属性名
CString g_szPropName = “Your Prop Name”; //自己定义一个属性名
HANDLE g_hValue = (HANDLE)1; //自己定义一个属性值
BOOL CALLBACK EnumWndProc(HWND hwnd,LPARAM lParam)
{
HANDLE h = GetProp(hwnd,g_szPropName);
if( h == g_hValue)
{
*(HWND*)lParam = hwnd;
return false;
}
return true;
}
3、在主窗口的 OnInitDialog()中添加属性 //设置窗口属性
SetProp(m_hWnd,g_szPropName,g_hValue);
探测Windows主机的NetBIOS信息
NetBIOS信息
在我们和远程Windows2000/XP主机建立了空会话之后，我们就有权枚举系统里的各项NetBIOS信息了。当然在某些选项中需要较高的权利，不过我们只执行那些匿名用户可以获得的绝大多数系统信息。
时间：探测远程主机的当前日期和时间信息。它会返回一个数据结构，包括年，月，日，星期，时，分，秒等等。不过得到的是GMT标准时间，当然对于我们来说就应该换算为GMT+8:00了。由此可以判断出主机所在的时区信息。
操作系统指纹：探测远程主机的操作系统指纹信息。一共有三种级别的探测（100，101，102），我们使用的是101级，它会返回一个数据结构，可以获取远程主机的平台标识，服务器名称，操作系统的主次版本（Windows2000为5.0,WindowsXP为5.1,而最新操作系统Longhorn的版本为6.0），服务器类型（每台主机可能同时包含多种类型信息）和注释。
共享列表：探测远程主机的共享列表。我们可以获得一个数据结构指针，枚举远程主机的所有共享信息（隐藏的共享列表在内）。其中包括共享名称，类型与备注。类型可分为：磁盘驱动器，打印队列，通讯设备，进程间通讯与特殊设备。
用户列表: 探测远程主机的用户列表，返回一个数据结构指针，枚举所有用户信息。可获取用户名，全名，用户标识符，说明与标识信息。标识信息可以探测用户的访问权限。
本地组列表: 探测远程主机的本地组列表信息。枚举所有本地组信息，包含本地组名称和注释信息。
组列表: 探测远程主机的组列表信息。枚举所有的组信息，包括组名称，注释，组标识符与属性。在此基础上，我们可以枚举组内的所有用户信息。
组用户列表: 探测特定组内的用户信息。我们可以获得组内所有用户的名称。当我门获得了所有的用户列表，下一步就应该很清楚了，那就是挂一个字典进行破解了。
传输协议列表: 探测远程主机的传输协议信息，枚举所有的传输列表。可以获得每个传输协议的名称，地址，网络地址和当前与本传输协议连接的用户数目。
会话列表: 探测远程主机的当前会话列表。枚举每个会话的相关信息，包括客户端主机的名称，当前用户的名称，活动时间和空闲时间。这可以帮助我们了解远程主机用户的喜好等等。
主要函数与相关数据结构分析
1. 建立空会话
WNetAddConnection2(&nr,username,password,0);
//nr为NETRESOURCE数据结构的对象；
//username为建立空会话的用户名，在此将用户名设置为NULL；
//password为登陆密码，在此将密码设置为NULL；
2. 撤消空会话
WNetCancelConnection2(ipc,0,TRUE);
//ipc为TCHAR的指针，我们可以这样获得：
//swprintf(ipc,_T(“\\\\%s\\ipc$”),argv[1])，argv[1]为主机名或地址；
3. 探测主机时间
nStatus=NetRemoteTOD(server,(PBYTE*)&pBuf);
//参数server为主机的名称或地址；
//pBuf为TIME_OF_DAY_INFO数据结构的指针；
//nStatus为NET_API_STATUS成员；
4. 探测操作系统指纹
NetServerGetInfo(server,dwLevel,(PBYTE *)&pBuf);
//dwLevel为等级数，我们选择的是101级；
//pBuf是SERVER_INFO_101数据结构的指针；
5. 探测共享列表
NetShareEnum(server,dwLevel,(PBYTE *)&pBuf,MAX_PREFERRED_LENGTH,&er,&tr,&resume );
//dwLevel的等级数为1级；
//pBuf是SHARE_INFO_1数据结构的指针；
//MAX_PREFERRED_LENGTH指定返回数据的长度；
//er指明返回的实际可以枚举的成员数目；
//tr返回所有的成员数目；
//resume用于继续进行共享搜索；
6. 探测用户列表
NetQueryDisplayInformation(server,dwLevel,i,100,0xFFFFFFFF,&dwRec,(PVOID *)&pBuf);
//dwLevel的等级数为1级；
//i为枚举的索引；
//dwRec返回获取的信息数目；
//pBuf为NET_DISPLAY_USER数据结构的指针；
7. 探测本地组列表
NetLocalGroupEnum(server,dwLevel,(PBYTE *)&pBuf,-1,&er,&tr,&resume);
//dwLevel的等级是1；
//pBuf返回LOCALGROUP_INFO_1数据结构的指针；
8. 探测组列表
NetQueryDisplayInformation(server,dwLevel,i,100,0xFFFFFFFF,&dwRec,(PVOID*)&pGBuf);
//dwLevel的等级为3；
//pGBuf返回NET_DISPLAY_GROUP的数据结构指针；
9. 探测组内的用户
NetGroupGetUsers(server,pGBuffer->grpi3_name,0,(PBYTE *)&pUBuf,MAX_PREFERRED_LENGTH,&er,&tr,&resum e);
//pGBuffer->grpi3_name为组的名称；
//pUBuf返回GROUP_USERS_INFO_0数据结构的指针；
10.探测传输协议列表
NetServerTransportEnum(server,dwLevel,(PBYTE *)&pBuf,MAX_PREFERRED_LENGTH,&er,&tr,&resume );
//dwLevel的等级为0级；
//pBuf返回SERVER_TRANSPORT_INFO_0数据结构的指针；
11.探测会话列表
NetSessionEnum(server,pszClient,pszUser,dwLevel,(PBYTE *)&pBuf,MAX_PREFERRED_LENGTH,&er,&tr,&resume );
//pszClient指定客户的地址；
//pszUser指定用户名；
//dwLevel的等级是10级；
//pBuf返回SESSION_INFO_10数据结构的指针；
12.释放内存
NetApiBufferFree(pBuf);
//释放由系统分配的内存空间。

分析IP地址（DDX）
编写Internet应用程序, 需要校验用户进入的IP地址和确认它是正确的.
首先，需要在对话框的头文件里加入下面的函数声明：
#include <winsock.h>
void WINAPI DDX_IPAddress(CDataExchange* pDX, int nIDC, UINT & value);
实现数据交换，你需要在你的对话框DoDataExchange函数里调用DDX_IPAddress函数。
现在，在对话框的实现文件中加入下列代码，不要忘记在项目设置中包含ws2_32.lib.
// DDX routine fo IP address translation
void WINAPI DDX_IPAddress(CDataExchange* pDX, int nIDC, UINT & value)
{
// from dialog to class ?
if( pDX->m_bSaveAndValidate)
{
CString Val;
BOOL bValid = true;
pDX->m_pDlgWnd->GetDlgItem(nIDC)->GetWindowText(Val );
for( int i = 0; i < Val.GetLength(); i++)
{
// let’s check if all entered char in entered
// IP address are digits
if(Val == ‘.’)
continue;
if(isdigit(Val) == 0)
{
bValid = false;
break;
}
}
if(bValid)
{
value = inet_addr(Val);
if(value == INADDR_NONE)
{
pDX->m_pDlgWnd->MessageBox(“The entered IP address is invalid.”);
pDX->PrepareEditCtrl(nIDC);
pDX->Fail();
}
}
else
{
pDX->m_pDlgWnd->MessageBox(“IP address can only have digits and dots.”);
pDX->PrepareEditCtrl(nIDC);
pDX->Fail();
}
}
else
{
// if the value is a valid IP address store it in the child control
in_addr IPaddress;
memcpy(&IPaddress, &value, 4);
CString Address = inet_ntoa(IPaddress);
if(!Address.IsEmpty())
{
pDX->m_pDlgWnd->GetDlgItem(nIDC)->SetWindowText(Add ress);
}
}
}
得到计算机的主机名和IP地址
#include<winsock2.h>
链接库：Wsock32.lib
{
WORD wVersionRequested;
WSADATA wsaData;
char name[255];
CString ip;
PHOSTENT hostinfo;
wVersionRequested = MAKEWORD( 2, 0 );
if ( WSAStartup( wVersionRequested, &wsaData ) == 0 )
{
if( gethostname ( name, sizeof(name)) == 0)
{
if((hostinfo = gethostbyname(name)) != NULL)
{
ip = inet_ntoa (*(struct in_addr *)*hostinfo->h_addr_list);
}
}
WSACleanup( );
}
}
晕啊
