Cybercriminals are increasingly inflicting more pain on ransomware victims by threatening to leak compromised data or use it in future spam attacks, if ransom demands aren t met. The tactic, called double extortion, first emerged in late 2019 by Maze operators, but has been rapidly adopted over the past few months by various cybercriminals behind the Clop, DoppelPaymer and Sodinokibi ransomware families. Double Extortion is a clear and growing ransomware attack trend, says researcher Lotem Finkelsteen.
