An anonymous hacker claims to have breached CIA Director John Brennan’s personal email account and has posted documents online, including a list of email addresses purportedly from Brennan’s contact file.

The CIA said it referred the matter to the proper authorities, but would not comment further.

The hacker also claims to have breached an account belonging to Homeland Security Secretary Jeh Johnson.

The New York Post first reported the hack. They described the hacker Sunday as “a stoner high school student,” motivated by his opposition to U.S. foreign policy and support for Palestinians. His Twitter account, @phphax, includes links to files that he told the Post he took from Brennan’s account.

The Post said he didn’t reveal his name or where he lived.
