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!

Using rainbow tables


In this recipe, we will learn about how to use rainbow tables with Kali. Rainbow tables are special dictionary tables that use hash values instead of standard dictionary passwords to achieve the attack. For our demonstration purposes, we will use RainbowCrack to generate our rainbow tables.

How to do it...

  1. Open a terminal window and change directories to the directory of rtgen:

    cd /usr/share/rainbowcrack/
    
  2. Next we are going to run rtgen to generate an MD5-based rainbow table:

    ./rtgen md5 loweralpha-numeric 1 5 0 3800 33554432 0
    
  3. Once your tables have been generated—a process that depends on the number of processors being used to generate the hashes (2-7 hours)—your directory will contain *.rt files.

  4. To begin the process of cracking the passwords, we will use the rtsort program to sort the rainbow tables to make it an easy process.

How it works...

In this recipe, we used various RainbowCrack tools to generate, sort, and crack an MD5 password. RainbowCrack works by brute-forcing...
