A British teen admitted he tried to hack into the computers of several high-ranking officials in the US, including the heads of the CIA and FBI.

Kane Gamble pleaded guilty Friday to 10 charges against him in Leicester crown court, the Guardian reported.

The 18-year-old targeted then-CIA Director John Brennon and former FBI Deputy Director Mark Giuliano, as well as Avril Haines, who served as deputy national security adviser under President Obama’s administration, and Obama’s former science and technology adviser John Holdren.

Eight of the charges were for performing a function with intent to secure unauthorized access to the computers. Two counts were for unauthorized modification of computer material.

Gamble, from Leicestershire, will be sentenced Dec. 15.
