A British man accused of launching cyber attacks against two large banks has appeared in court after being extradited from Germany.
Daniel Kaye allegedly developed malicious software known as a botnet that enabled him to take control of remote computers. He then used it to target Lloyds Banking Group and Barclays in January, preventing some customers from using their accounts after the banks declined to pay him a ransom, according to prosecutors.
It is estimated it cost Lloyds £190,000 to get its internet services back online, while Barclays paid about £146,000 to get its systems fully up and running again.
In one email to a potential client, Mr Kaye allegedly boasted he had between 555,000 and 1.5 million computers in his botnet, the court heard.
He faces nine charges under the Computer Misuse Act, two of blackmail and one of possession of criminal property.
