Web Penetration Testing with Kali Linux

Overview of this book

Kali Linux is built for professional penetration testing and security auditing. It is the next-generation of BackTrack, the most popular open-source penetration toolkit in the world. Readers will learn how to think like real attackers, exploit systems, and expose vulnerabilities. Even though web applications are developed in a very secure environment and have an intrusion detection system and firewall in place to detect and prevent any malicious activity, open ports are a pre-requisite for conducting online business. These ports serve as an open door for attackers to attack these applications. As a result, penetration testing becomes essential to test the integrity of web-applications. Web Penetration Testing with Kali Linux is a hands-on guide that will give you step-by-step methods on finding vulnerabilities and exploiting web applications. "Web Penetration Testing with Kali Linux" looks at the aspects of web penetration testing from the mind of an attacker. It provides real-world, practical step-by-step instructions on how to perform web penetration testing exercises. You will learn how to use network reconnaissance to pick your targets and gather information. Then, you will use server-side attacks to expose vulnerabilities in web servers and their applications. Client attacks will exploit the way end users use web applications and their workstations. You will also learn how to use open source tools to write reports and get tips on how to sell penetration tests and look out for common pitfalls. On the completion of this book, you will have the skills needed to use Kali Linux for web penetration tests and expose vulnerabilities on web applications and clients that access them.

Web session tools


The next section will cover tools used for Penetration Testing web sessions. Some tools are not available in Kali1.0; however, they can be obtained online.

Firefox plugins

The manual method to perform a session hijack is stealing a victim's authentication cookie. One way to accomplish this is injecting a script on a compromised web application server so cookies are captured without the victim's knowledge. From there, the attacker can harvest authentication cookies and use a cookie injector tool to replace the attacker's cookie with an authorized stolen cookie. Other methods used to steal cookies are packet sniffing, network traffic, and compromising hosts. Stealing cookies will be covered later in this book.

The Firefox web browser offers many plugins that can be used to inject stolen cookies into an attacker's browser. Some examples are GreaseMonkey, Cookie Manager, and FireSheep. We suggest browsing the Firefox plugins marketplace for various cookie management offerings...
