Gaining access

In this part of the chapter, we will learn how to gain access to computer systems. There are two methods to hack a computer:

• Server-side attacks
• Client-side attacks

When learning about server-side attacks, you will see how to discover weaknesses in the programs installed on the target computer, and how to use those weaknesses to gain full access to the computer.

In the client-side attacks, you're going to learn how to use social engineering to hack into the target, you'll learn how to create undetectable backdoors, backdoors that look like images and pictures, and so on. We will also learn how to gain access to any computer if that computer exists in our network by using fake updates or by using fake downloads.
