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!

Operating system fingerprinting


At this point of the information gathering process, we should now have documented a list of IP addresses, active machines, and open ports identified from the target organization. The next step in the process is determining the running operating system of the active machines in order to know the type of systems we're pentesting.

Getting ready

A Wireshark capture file is needed in order to complete step 2 of this recipe.

How to do it...

Let's begin the process of OS fingerprinting from a terminal window:

  1. Using Nmap, we issue the following command with the -O option to enable the OS detection feature:

    nmap -O 192.168.56.102
    
  2. Use p0f to analyze a Wireshark capture file:

    p0f -s /tmp/targethost.pcap -o p0f-result.log -l
    
    p0f - passive os fingerprinting utility, version 2.0.8
    (C) M. Zalewski <[email protected]>, W. Stearns <[email protected]>
    p0f: listening (SYN) on 'targethost.pcap', 230 sigs (16 generic), rule: 'all'.
