REvil ransomware developers say they made more than $100 million in one year by extorting large businesses across the world from various sectors. The cybercriminal operation has encrypted computers at big-name companies, among them Travelex, Brown-Forman, SeaChange International, CyrusOne, Artech Information Systems, Albany International Airport, Kenneth Cole, and GEDIA Automotive Group. The most profitable targets for REvil are companies in the insurance, legal, and agriculture sectors. REvil is also thinking to adopt another tactic designed to increase their odds of getting paid: hitting the victim with a DDoS attack.
