FBI investigates claim that hacker broke into CIA director’s private e-mail

The FBI is investigating claims by an anonymous computer hacker that he stole potentially sensitive files from the private e-mail account of CIA Director John Brennan and posted them online, U.S. officials said.

The exposed documents appear to include a roster of senior U.S. national security officials with their phone and Social Security numbers, a log of calls made by former CIA deputy director Avril Haines and a list of e-mail addresses that the hacker claimed were taken from Brennan’s AOL account.

A CIA spokesman said, “We are aware of the reports that have surfaced on social media and have referred the matter to the appropriate authorities.”
