Overview of this book

An Advanced Persistent Threat (APT) is a severe form of cyberattack that lies low in the system for a prolonged time and locates and then exploits sensitive information. Preventing APTs requires a strong foundation of basic security techniques combined with effective security monitoring. This book will help you gain a red team perspective on exploiting system design and master techniques to prevent APT attacks. Once you’ve understood the internal design of operating systems, you’ll be ready to get hands-on with red team attacks and, further, learn how to create and compile C source code into an EXE program file. Throughout this book, you’ll explore the inner workings of how Windows systems run and how attackers abuse this knowledge to bypass antivirus products and protection. As you advance, you’ll cover practical examples of malware and online game hacking, such as EXE infection, shellcode development, software packers, UAC bypass, path parser vulnerabilities, and digital signature forgery, gaining expertise in keeping your system safe from this kind of malware. By the end of this book, you’ll be well equipped to implement the red team techniques that you've learned on a victim's computer environment, attempting to bypass security and antivirus products, to test its defense against Windows APT attacks.

tinyLinker example

This example is from the tinyLinker project. It can be found under the Chapter#2 folder of this book’s GitHub project, which is publicly available. To save space, we only extracted the highlighted code; the complete source code should be referred to if you wish to look at the full project for detailed reading.

Now that you have learned how to generate a linker for an executable, next, you need to learn how to generate a PE program linker from scratch. We’ll take a hands-on approach to this in this section:

We assume that a simple executable should have at least three structure headers – that is, a DOS Header, NT Headers, and Section Headers, respectively. (Note that the File Header and Optional Header are part of the NT Headers). The contents of this section are appended to the ends of these headers.

In lines 26-31 of the code, the size of the entire program...
