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.

Digital Signature – Authenticode Verification

For Windows users, it is common practice to install anti-virus software, update systems regularly, choose the source of downloads carefully, and double-check that applications are digitally signed by reputable technology companies. However, are these security practices really enough to keep hackers at bay? This chapter may give readers a very different perspective. In this chapter, we will learn about Windows Authenticode specification, reverse-engineering the signature verification function, WinVerifyTrust, and how to hijack well-known digital signatures.

This chapter is based on the public presentation Subverting Trust in Windows given by Matt Graeber, a security researcher at Specter Ops, at the TROOPERS18 conference in 2018. It introduced how to manage trusted certificate authorities (trust providers), the calculation process for signing certificates, the corresponding authentication API, and malicious exploits in the Windows...
