Overview of this book

If you want to analyze software in order to exploit its weaknesses and strengthen its defenses, then you should explore reverse engineering. Reverse Engineering is a hackerfriendly tool used to expose security flaws and questionable privacy practices.In this book, you will learn how to analyse software even without having access to its source code or design documents. You will start off by learning the low-level language used to communicate with the computer and then move on to covering reverse engineering techniques. Next, you will explore analysis techniques using real-world tools such as IDA Pro and x86dbg. As you progress through the chapters, you will walk through use cases encountered in reverse engineering, such as encryption and compression, used to obfuscate code, and how to to identify and overcome anti-debugging and anti-analysis tricks. Lastly, you will learn how to analyse other types of files that contain code. By the end of this book, you will have the confidence to perform reverse engineering.

Debuggers

When debugging tools are used, this would mean that we are in the code-tracing phase of our analysis. Debuggers are used to step in every instruction the program is supposed to do. In the process of debugging, actual interaction and changes in memory, disk, network, and devices can be identified:

x86dbg: This is a Windows user-mode debugger. It is open source and can debug 32- and 64-bit programs. It is capable of accepting plugins written by users. The source code can be downloaded from https://github.com/x64dbg. The builds can be downloaded from https://x64dbg.com.
IDA Pro: Paid versions of IDA Pro are capable of debugging using the same disassembly interface. It is very useful when you want to see a graphical view of decrypted code.
