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.

PE to Shellcode – Transforming PE Files into Shellcode

You now have a solid foundation of knowledge on how to design a minimalist application loader. We can move on to how to convert any executable directly into shellcode without having to write the shellcode. In this chapter, we will introduce how to write a lightweight loader in x86 assembly that can be used to convert any EXE file to shellcode.

In this chapter, we’re going to cover the following main topics:

  • Parsing Kernel32’s export table in x86 assembly
  • Getting API addresses in x86 assembly
  • File mapping and repairing the import table in x86
  • Handling relocation in x86
  • An example of PE to shellcode
