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.

Chapter 6: Collecting Ransomware-Related Cyber Threat Intelligence

As you've learned from the previous chapter, ransomware affiliates may use a wide variety of tactics, techniques, and procedures (TTPs), so knowing what exactly they are using in the attack you are responding to seems quite a good idea. Some of these tactics and techniques might be for short games, while others may be for long-term positions—it really depends upon the end goal of the threat actor.

Usually, the first thing you learn starting an incident response (IR) engagement is the ransomware strain used by threat actors. As many ransomware strains are distributed under a ransomware-as-a-service (RaaS) model, various affiliates may have various approaches to the attack life cycle, so their TTPs may vary as well.

Taking this fact into consideration, it's a very good idea to have proper cyber threat intelligence (CTI) to aid your engagement. Of course, commercial CTI platforms are of great help...
