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!

Determining network range


With the gathered information obtained by following the previous recipe of this chapter, we can now focus on determining the IP addresses range from the target network. In this recipe, we will explore the tools needed to achieve it.

How to do it...

Let's begin the process of determining the network range by opening a terminal window:

  1. Open a new terminal window and issue the following command:

    dmitry -wnspb targethost.com -o /root/Desktop/dmitry-result
    
  2. When finished, we should now have a text document on the desktop with filename dmitry-result.txt, filled with information gathered from the target:

  3. To issue an ICMP netmask request, type the following command:

    netmask -s targethost.com
    
  4. Using scapy, we can issue a multiparallel traceroute. To start it, type the following command:

    scapy
    
  5. With scapy started, we can now enter the following function:

    ans,unans=sr(IP(dst="www.targethost.com/30", ttl=(1,6))/TCP())
    
  6. To display the result in a table, we issue the following function...
