Kali Linux Web Penetration Testing Cookbook

By: Gilberto Najera-Gutierrez

Overview of this book

Web applications are a huge point of attack for malicious hackers and a critical area for security professionals and penetration testers to lock down and secure. Kali Linux is a Linux-based penetration testing platform and operating system that provides a huge array of testing tools, many of which can be used specifically to execute web penetration testing. This book will teach you, in the form step-by-step recipes, how to detect a wide array of vulnerabilities, exploit them to analyze their consequences, and ultimately buffer attackable surfaces so applications are more secure, for you and your users. Starting from the setup of a testing laboratory, this book will give you the skills you need to cover every stage of a penetration test: from gathering information about the system and the application to identifying vulnerabilities through manual testing and the use of vulnerability scanners to both basic and advanced exploitation techniques that may lead to a full system compromise. Finally, we will put this into the context of OWASP and the top 10 web application vulnerabilities you are most likely to encounter, equipping you with the ability to combat them effectively. By the end of the book, you will have the required skills to identify, exploit, and prevent web application vulnerabilities.

Using John the Ripper to generate a dictionary

John the Ripper is perhaps the favorite password cracker of most penetration testers and hackers in the world. It has lots of features, such as automatically recognizing the most common encryption and hashing algorithms, being able to use dictionaries, and brute force attacks; thus, enabling us to apply rules to dictionary words, to modify them, and to have a richer word list while cracking without the need of storing that list. This last feature is the one that we will use in this recipe to generate an extensive dictionary based on a very simple word list.

Getting ready

We will use the word list generated in the previous recipe, Password profiling with CeWL, to generate a dictionary of possible passwords.

How to do it...

  1. John has the option of only showing the passwords that he will use to crack a certain password file. Let's try it with our word list:

    john --stdout --wordlist=cewl_WackoPicko.txt
  2. Another feature John has, as mentioned before, lets...
