Features have been merged from\nthese two malware families to create a different RAT class for the group. We’ve decided\nto call this umbrella of malware “Ketrum.”\nThe new samples we found continue the Ke3chang group’s strategy of using a basic\nbackdoor to gain control over the victim’s device, so that an operator can then connect to\nit and run commands manually to conduct further operations.\nInformation Malpedia AlienVault OTX Last change to this tool card: 24 April 2021\nDownload this tool card
