WikiLeaks on Wednesday posted material from what appears to be CIA director John Brennan’s personal email account, including a draft security clearance application containing personal information.

The material presumably was taken in a compromise of Brennan’s email account by a hacker who told The New York Post he is a high school student protesting American foreign policy. The hacker claimed he posed as a Verizon employee and tricked another employee into revealing Brennan’s personal information.

Brennan was seeking security clearance while applying for a job as White House counter-terrorism adviser. It was not immediately clear whether any national security information was compromised in the release of the clearance application, which includes his wife’s Social Security number and the names of the people Brennan worked with over a long career at the CIA earlier.
