Antivirus Bypass Techniques

By: Nir Yehoshua, Uriel Kosayev

Overview of this book

Antivirus software is built to detect, prevent, and remove malware from systems, but this does not guarantee the security of your antivirus solution as certain changes can trick the antivirus and pose a risk for users. This book will help you to gain a basic understanding of antivirus software and take you through a series of antivirus bypass techniques that will enable you to bypass antivirus solutions. The book starts by introducing you to the cybersecurity landscape, focusing on cyber threats, malware, and more. You will learn how to collect leads to research antivirus and explore the two common bypass approaches used by the authors. Once you’ve covered the essentials of antivirus research and bypassing, you'll get hands-on with bypassing antivirus software using obfuscation, encryption, packing, PowerShell, and more. Toward the end, the book covers security improvement recommendations, useful for both antivirus vendors as well as for developers to help strengthen the security and malware detection capabilities of antivirus software. By the end of this security book, you'll have a better understanding of antivirus software and be able to confidently bypass antivirus software.

Summary

To summarize this chapter of the book, antivirus bypasses will always be relevant for a variety of reasons, such as the following:

  • Code that is not written securely
  • A component that does not work properly.

In this chapter, you have gained knowledge and understanding of the importance of securing antivirus software from vulnerability and detection-based bypassed.

In order to protect antivirus engines from bypasses, it is first necessary to perform and test bypass attempts, in order to know exactly where the security vulnerability is located. Once the security vulnerability is found, a fix must be implemented so attackers cannot exploit the vulnerability. Of course, antivirus code must be regularly maintained, because from time to time more vulnerabilities can arise and be found.

These recommendations are based on our research and extensive tests conducted over a number of years that are also based on major...
