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...
