Overview of this book

In this age, where online information is at its most vulnerable, knowing how to execute the same attacks that hackers use to break into your system or network helps you plug the loopholes before it's too late and can save you countless hours and money. Kali Linux is a Linux distribution designed for penetration testing and security auditing. It is the successor to BackTrack, the world's most popular penetration testing distribution. Discover a variety of popular tools of penetration testing, such as information gathering, vulnerability identification, exploitation, privilege escalation, and covering your tracks. Packed with practical recipes, this useful guide begins by covering the installation of Kali Linux and setting up a virtual environment to perform your tests. You will then learn how to eavesdrop and intercept traffic on wireless networks, bypass intrusion detection systems, and attack web applications, as well as checking for open ports, performing data forensics, and much more. The book follows the logical approach of a penetration test from start to finish with many screenshots and illustrations that help to explain each tool in detail. The Kali Linux Cookbook will serve as an excellent source of information for the security professional and novice alike!

Man In The Middle (MITM) attack


In this recipe, we will use a Man In The Middle (MITM) attack against one of our targets. A MITM attack works by allowing us to eavesdrop on the communication between our target and their legitimate party. For our example, we could utilize Ettercap to eavesdrop on the communication of a Windows host while checking their e-mail on http://www.yahoo.com.

Getting ready

To execute this recipe we will need the following:

  • A wireless connection to the network

  • A machine on the network connected to the wireless network

How to do it...

Let's begin the Man In The Middle attack by launching Ettercap.

  1. Open a terminal window and start Ettercap. Using the –G option launches the GUI (Graphical User Interface):

    ettercap –G
    
  2. We begin the process by turning on unified sniffing. You can press Shift + U or use the menu and go to Sniff | Unified sniffing..., as shown in the following screenshot:

  3. Select the network interface. In the case of using a MITM attack, we should select our wireless...
