By: Himanshu Sharma

Overview of this book

With the current rate of hacking, it is very important to pentest your environment in order to ensure advanced-level security. This book is packed with practical recipes that will quickly get you started with Kali Linux (version 2016.2) according to your needs, and move on to core functionalities. This book will start with the installation and configuration of Kali Linux so that you can perform your tests. You will learn how to plan attack strategies and perform web application exploitation using tools such as Burp, and Jexboss. You will also learn how to perform network exploitation using Metasploit, Sparta, and Wireshark. Next, you will perform wireless and password attacks using tools such as Patator, John the Ripper, and airoscript-ng. Lastly, you will learn how to create an optimum quality pentest report! By the end of this book, you will know how to conduct advanced penetration testing thanks to the book’s crisp and task-oriented recipes.

Generating word list with crunch

Crunch is a word list generator. It uses permutations and combinations to generate all possible combinations of the supplied character set.

How to do it...

To learn about Crunch follow the given steps:

  1. Crunch is preinstalled with Kali, and we can launch it with this command:
        crunch -h
  1. As we see, it is easy to use to generate a password list of a minimum of two characters and maximum of two characters containing only abcdef, and we can use the following command:
        crunch 2 2 abcdef

We can see that the word list has been generated:

  1. To save it in a file, we can use the -o switch. Crunch also has an inbuilt list containing a predefined character set. It can be found at /usr/share/crunch/charset.lst.
  1. To use a charset, we use the -f switch:
        crunch 2 2 -f /usr/share/crunch/charset.lst lalpha

The following screenshot shows the output of the preceding command:

  1. This will generate a list of a minimum length and maximum length of 2, containing lowercase alphabets...
