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 Native Compiled Applications

Compiled software that runs in a native execution environment has historically been plagued by vulnerabilities such as buffer overflows and format string bugs. Most web applications are written using languages and platforms that run in a managed execution environment in which these classic vulnerabilities do not arise. One of the most significant advantages of languages such as C# and Java is that programmers do not need to worry about the kind of buffer management and pointer arithmetic problems that have affected software developed in native languages such as C and C++ and that have given rise to the majority of critical bugs found in that software.

Nevertheless, you may occasionally encounter web applications that are written in native code. Also, many applications written primarily using managed code contain portions of native code or call external components that run in an unmanaged context. Unless you know for certain that your target...
