Mastering Reverse Engineering

By: Reginald Wong

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.

Other file-types


Nowadays, websites usually convert binary data to printable ASCII text in order for the site developers to easily embed this data along with the HTML scripts. Others simply convert data to something that is not easy for humans to read. In this section, we will aim to decode data that has been hidden from plain understandable form. In Chapter 13 Reversing various File-types, we will deal more with how to reverse other File-Types besides Windows and Linux executables. In the meantime, we will just decode obvious data.

 

 

Let us head to our browsers and visit www.google.com, at the time of writing (we stored a copy of the source at https://github.com/PacktPublishing/Mastering-Reverse-Engineering/blob/master/ch10/google_page_source.txt), viewing the source would show us a portion that has a b64 encoded text, as in the following screenshot:  

 

 

Using Cyberchef, a tool which can help decode various types of encoded data including base 64, we can deduce this data to something we understand...
