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.

Attacking the Browser

The attacks described so far in this and the preceding chapter involve exploiting some feature of an application's behavior to compromise users of the application. Attacks such as cross-site scripting, cross-site request forgery, and JavaScript hijacking all arise from vulnerabilities within specific web applications, even though the details of some exploit techniques may leverage quirks within specific browsers.

A further category of attacks against users does not depend on the behavior of specific applications. Rather, these attacks rely solely on features of the browser's behavior, or on the design of core web technologies themselves. These attacks can be delivered by any malicious website or by any benign site that has itself been compromised. As such, they lie at the edge of the scope of a book about hacking web applications. Nevertheless, they are worthy of brief consideration partly because they share some features with attacks that exploit application...
