Hackers who claim they were behind a data breach at Revolut have threatened to sell the confidential records of hundreds of customers to other criminal groups unless the British online bank pays a ransom of $3mn within 24 hours. The group, which calls itself iamnotavillain, published the ultimatum online on Wednesday afternoon next to a digital countdown clock. The public demand is unusual given hackers usually prefer to make ransom requests privately and go public only if the target refuses to pay or engage, usually by publishing details of the hack on a dark-web leak site. The message told Revolut to pay “6,000 XMR / $3,000,000 . . . otherwise all the data will be sold, and the blood will be on your hands”. XMR is the cryptocurrency Monero, which is popular with hackers given its transactions are difficult to trace.
