Justice Department recovers most of $2.3 million payment made to hackers after cyberattack on nation’s largest fuel pipeline

Georgia-based Colonial Pipeline, which supplies roughly half the fuel consumed on the East Coast, temporarily shut down its operations on May 7 after a gang of cybercriminals using the DarkSide ransomware variant broke into its computer system. The ransomware variant used by DarkSide, which has been the subject of an FBI investigation for the last year, is one of more than 100 that law enforcement officials have identified, said FBI Deputy Director Paul Abbate.
