Ransomware group Avaddon has shut down its criminal enterprise after landing in the crosshairs of law-enforcement agencies in the U.S. and Australia. Avaddon released its decryption keys to BleepingComputer 2,934 in total with each key belonging to an individual victim. Law enforcement said the average ransom demanded by the group was about $40,000, meaning they quit and just walked away from millions. The group spent the days following the alert collecting as many payments as possible before releasing the keys.
