Hacker's Guide to Reverse Engineering begins with a basic primer on reverse engineering, including computer internals, operating systems, and assembly language. From there, readers will be taken through various applications of reverse engineering.  These applications, which comprise the core of the book, are presented in two parts.  The first part deals with security-related reverse engineering. In this part we will be teaching how to reverse engineer various copy protection technologies, software, and viruses. The following part will deal with the more practical aspects of the trade reverse engineering for software developers. Here he will discuss more conventional situations where reverse engineering is required such as reverse engineering a 3rd party software library for better interfacing and reverse engineering a competitors product to build a better product. Throughout the text, the author will cover the legal aspects of what he is demonstrating.  The final part of the book will provide an in-depth guide to disassembly (or code-level reverse engineering). This will be a technical guide to deciphering assembly language and will demonstrate advanced reverse engineering techniques
