James Clapper. AP Just months after reports that someone was hacking the personal email of John Brennan, the CIA director, a US intelligence official is confirming that online personal accounts linked to Director of National Intelligence James Clapper also have been hacked.

DNI spokesman Brian Hale said Tuesday that Clapper's office was aware of the hacking and had reported the incident to appropriate authorities.

He declined to provide other details.

An individual not authorized to discuss details who spoke only on condition of anonymity said the Office of the Director of National Intelligence was aware of the hacking incident before it was first reported Tuesday by Motherboard, an online magazine and video channel on science and technology.

Motherboard reported that the same teenage hacker who broke into Brennan's account also targeted Clapper.

Brennan said in October that he was outraged that someone hacked his personal email account and publicized sensitive data, including his contact list and his wife's Social Security number.

The hacker — identified by Motherboard as "Cracka" — has said he is a high-school student protesting US policy.

He said he fooled Verizon into providing him access to Brennan's account. After Cracka gained control of the Verizon account, he told Motherboard, the teenager "changed the settings so that every call to his house number would get forwarded to the Free Palestine Movement."

Brennan denied any impropriety on his part and said the hacking incident underscored that everyone was vulnerable to the compromise of personal information on the internet.
