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.

Import Address Table in PE

As we mentioned in Chapter 1, From Source to Binaries – The Journey of a C Program, when a program is executed, the following procedure is performed. First, a new process is created and the static contents are loaded into it as a file map; the first thread of this process then calls the loader function located in ntdll.dll. After the necessary corrections have been made to the PE module mounted in memory, the entry function of the EXE module can be executed and the program will run normally as a process.

In this chapter, we will look more closely at the application loader that comes by default with the operating system. This variation can be used to develop a program packer, fileless attacks, staged payloads (such as staged payloads in Metasploit), and so on.

Let’s go back to the basics first. Figure 5.1 is identical to Figure 1.3 and illustrates a program that will pop up a message with MessageBoxA:
