Kali Linux Cookbook

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!

Port redirection


In this recipe, we will use Kali to perform port redirection, also known as port forwarding or port mapping. Port redirection involves the process of accepting a packet destined for one port, say port 80, and redirecting its traffic to a different port, such as 8080. The benefits of being able to perform this type of attack are endless because with it you can redirect secure ports to unsecure ports, redirect traffic to a specific port on a specific device, and so on.

How to do it...

Let's begin the process of port redirection/forwarding.

  1. Open a terminal window and execute the following command to configure IP tables that will allow our machine to route traffic:

    Sudo echo 1 >> /proc/sys/net/ipv4/ip_forward
    
  2. Next, we launch arpspoof to poison traffic going to our default gateway. In this example, the IP address of our default gateway is 192.168.10.1. Arpspoof has a couple of options that we will select and they include:

    • –i allows us to select our target interface. In this...
