Ransomware gangs are increasingly failing to keep their promise to delete stolen data after a victim pays a ransom. In 2019, the Maze ransomware group introduced a new tactic known as double-extortion, which is when attackers steal unencrypted files and then threaten to release them publicly if a ransom is not paid. Now, victims are being extorted through the encryption of their files and the risk of their data being published and causing a data breach.
