黑客编程教程（十一）获得系统详细信息

木马程序一般都能获得系统详细信息,下面的代码获得计算机名,内存容量,驱动器类型: 
 

#include<stdio.h>

#include<windows.h>

 

void GetSysInfo();

 

DWORD GetOS() 

{ 

OSVERSIONINFO os; 

 

 

os.dwOSVersionInfoSize=sizeof(OSVERSIONINFO); 

GetVersionEx(&os); 

switch(os.dwPlatformId) 

{ 

case VER_PLATFORM_WIN32_WINDOWS: 

return VER_PLATFORM_WIN32_WINDOWS; 

 

case VER_PLATFORM_WIN32_NT: 

return VER_PLATFORM_WIN32_NT; 

} 

return 0;

} 

 

VOID GetSysInfo() 

{ 

TCHAR szBuff[MAX_PATH]; 

TCHAR szTemp[MAX_PATH]; 

 

 

wsprintf(szBuff,"\n\n\r<<System Information>>\n\n\r"); 

printf("%s",szBuff);

 

//计算机名 

DWORD len=sizeof(szTemp); 

GetComputerName(szTemp,&len); 

wsprintf(szBuff,"Computer Name: %s\n\n\r",szTemp); 

printf("%s",szBuff);

 

//当前操作系统 

switch(GetOS()) 

{ 

case VER_PLATFORM_WIN32_WINDOWS: 

lstrcpy(szTemp,"Windows 9x"); 

break; 

case VER_PLATFORM_WIN32_NT: 

lstrcpy(szTemp,"Windows NT/2000"); 

break; 

} 

wsprintf(szBuff,"Option System: %s\n\n\r",szTemp); 

printf("%s",szBuff);

 

//内存容量 

MEMORYSTATUS mem; 

mem.dwLength=sizeof(mem); 

GlobalMemoryStatus(&mem); 

wsprintf(szBuff,"Total Memroy: %dM\n\n\r",mem.dwTotalPhys/1024/1024+1); 

printf("%s",szBuff);

 

//系统目录 

TCHAR szPath[MAX_PATH]; 

GetWindowsDirectory(szTemp,sizeof(szTemp)); 

GetSystemDirectory(szBuff,sizeof(szBuff)); 

wsprintf(szPath,"Windows Directory: %s\n\n\rSystem Directory: %s\n\n\r",szTemp,szBuff); 

printf("%s",szBuff);

 

//驱动器及分区类型 

TCHAR szFileSys[10]; 

 

for(int i=0;i<26;++i) 

{ 

wsprintf(szTemp,"%c:\\",'A'+i); 

UINT uType=GetDriveType(szTemp); 

switch(uType) 

{ 

case DRIVE_FIXED: 

GetVolumeInformation(szTemp,NULL,NULL,NULL,NULL,NULL,szFileSys,MAX_PATH); 

wsprintf(szBuff,"Hard Disk: %s (%s)\n\n\r",szTemp,szFileSys); 

printf("%s",szBuff);

break; 

case DRIVE_CDROM: 

wsprintf(szBuff,"CD-ROM Disk: %s\n\n\r",szTemp); 

printf("%s",szBuff);

break; 

case DRIVE_REMOTE: 

GetVolumeInformation(szTemp,NULL,NULL,NULL,NULL,NULL,szFileSys,MAX_PATH); 

wsprintf(szBuff,"NetWork Disk: %s (%s)\n\n\r",szTemp,szFileSys); 

printf("%s",szBuff);

break; 

} 

} 

 

} 

int main(void )

{

GetSysInfo();

return 0;

 

}
