Incident Response Techniques for Ransomware Attacks

Overview of this book

Ransomware attacks have become the strongest and most persistent threat for many companies around the globe. Building an effective incident response plan to prevent a ransomware attack is crucial and may help you avoid heavy losses. Incident Response Techniques for Ransomware Attacks is designed to help you do just that. This book starts by discussing the history of ransomware, showing you how the threat landscape has changed over the years, while also covering the process of incident response in detail. You’ll then learn how to collect and produce ransomware-related cyber threat intelligence and look at threat actor tactics, techniques, and procedures. Next, the book focuses on various forensic artifacts in order to reconstruct each stage of a human-operated ransomware attack life cycle. In the concluding chapters, you’ll get to grips with various kill chains and discover a new one: the Unified Ransomware Kill Chain. By the end of this ransomware book, you’ll be equipped with the skills you need to build an incident response strategy for all ransomware attacks.

Summary

In this chapter, we have looked at various sources of ransomware-related CTI. We've analyzed a couple of open source reports and extracted valuable pieces of data to allow us to reconstruct various parts of the attack life cycle and transform them into CTI.

We've learned how to analyze social media to extract pieces of cyber threat data shared by representatives of the cyber security community.

Finally, we've looked deep into underground forums and learned how to receive CTI directly from the adversary—ransomware affiliates.

Now, as you've already learned a lot about human-operated ransomware attacks and have a clear understanding of how such attacks actually work, you are ready to dive into the process of investigation.

In the next chapter, we'll look at the main sources of digital forensic artifacts that allow incident responders to reconstruct a human-operated ransomware attack and understand what exactly was done during its life...
