Double Extortion Ransomware

Double extortion ransomware is a type of ransomware attack in which the attackers not only encrypt data, they also threaten to leak the data publicly if the ransom is not paid. The intent is to add an extra incentive for victims to pay the ransom – especially those victims who may otherwise elect not to pay because they have backup files.
