The Web Application Hacker's Handbook

By: Dafydd Stuttard, Marcus Pinto

Overview of this book

Web applications are the front door to most organizations, exposing them to attacks that may disclose personal information, execute fraudulent transactions, or compromise ordinary users. This practical book has been completely updated and revised to discuss the latest step-by-step techniques for attacking and defending the range of ever-evolving web applications. Youíll explore the various new technologies employed in web applications that have appeared since the first edition and review the new attack techniques that have been developed, particularly in relation to the client side. The book starts with the current state of web application security and the trends that indicate how it is likely to evolve soon. Youíll examine the core security problem affecting web applications and the defence mechanisms that applications implement to address this problem, and youíll also explore the key technologies used in todayís web application. Next, youíll carry out tasks for breaking into web applications and for executing a comprehensive attack. As you progress, youíll learn to find vulnerabilities in an application's source code and review the tools that can help when you hack web applications. Youíll also study a detailed methodology for performing a comprehensive and deep attack against a specific target. By the end of this book, youíll be able to discover security flaws in web applications and how to deal with them.

Putting It All Together: Burp Intruder

The JAttack tool consists of fewer than 250 lines of simple code, yet in a few seconds, it uncovered at least two potentially serious security vulnerabilities while fuzzing a single request to an application.

Nevertheless, despite its power, as soon as you start to use a tool such as JAttack to deliver automated customized attacks, you will quickly identify additional functionality that would make it even more helpful. As it stands, you need to configure every targeted request within the tool's source code and then recompile it. It would be better to read this information from a configuration file and dynamically construct the attack at runtime. In fact, it would be much better to have a nice user interface that lets you configure each of the attacks described in a few seconds.

There are many situations in which you need more flexibility in how payloads are generated, requiring many more advanced payload sources than the ones we have created...
