How Ransomware Attacks

What defenders should know about the most prevalent and persistent malware families.

Ransomware’s behavior is its Achilles' heel, which is why Sophos spends so much time studying it.

Our goal is to give security operators a guideline to understand the core behaviors that underlie ransomware attacks, which we also use to convict ransomware with Sophos' behavioral engine, Intercept X.
