Cybercrime is a psychological game and ransomware operators are making clever use of the fear and anxiety of victims to maximize the chances of a payout. In a new update, the Ragnar Locker ransomware gang has threatened its victims of leaking their stolen data if they contact law enforcement agencies or data recovery experts. This mounts an added pressure on the victims who are not willing to pay the ransom.
