Cuba Ransomware Overview

Over the past year, we have seen ransomware attackers change the way they have responded to organizations that have either chosen to not pay the ransom or have recovered their data via some other means. At the end of the day, fighting ransomware has resulted in the bad actors’ loss of revenue. Being the creative bunch they are, they have resorted to data dissemination if the ransom is not paid.
