A teenager who tricked his way into obtaining the email and phone accounts of senior US intelligence officials has been sentenced.
Kane Gamble, 18, targeted CIA, FBI and US Department of Justice databases from his bedroom in Leicestershire.
The Old Bailey was told Gamble, who has admitted a number of charges, damaged the “effectiveness” of the wider law enforcement community.
He will serve two years at a youth detention centre.
His defence said he was “naive” and never meant to “harm” any individuals.
But the judge said Gamble ran a “campaign of cyber terrorism”.
Gamble obtained “extremely sensitive” documents on military and intelligence operations in Iraq and Afghanistan, the court was told.
Between June 2015 and February 2016, he targeted the former CIA chief John Brennan and FBI deputy director Mark Giuliano from his home in Linford Crescent, Coalville.
The judge was told he impersonated his victims and conned call centres into divulging confidential information.
He then sent emails from agents’ accounts and accessed sensitive military information.
The court was also told Gamble uploaded details of 20,000 FBI employees obtained from the US Department of Justice, with the message “This is for Palestine”.
Gamble even managed to use the TV in the house of then US Secretary of Homeland Security Jeh Johnson to post the message “I own you”.
