Prosecutor Kevin Barry told jurors at London’s Southwark Crown Court last week that the 17-year-old hacked into the City of London Police’s cloud storage weeks after the force arrested him in connection with the attack on BT and EE.
Barry said Kortag later embarked on a solo cybercrime spree, first targeting Revolut, then Uber two days later, before Rockstar Games was hacked.
Cortag was assessed by psychiatrists as unfit to stand trial, so the jury would determine whether he committed the acts rather than return a guilty or not guilty verdict.
He has been charged with 12 offenses, including three counts of racketeering, two counts of fraud and six counts under the Computer Misuse Act.
The 17-year-old is being tried on two counts of racketeering, two counts of fraud and three counts under the Computer Misuse Act of hacking BT and Nvidia, which he denies.
He previously pleaded guilty to two offenses under the Computer Misuse Act and one count of fraud.
