A hacking collective appears to have obtained a collection of sensitive data by hacking into the AOL email account of CIA Director John Brennan, based on the hackers' tweets and news reports.
The group, which calls itself "Crackass With Attitude" or CWA, released a list of alleged intelligence community employees, along with their alleged personal emails and Social Security numbers on Twitter on Monday afternoon.
Last week, the hackers released a screenshot that appears to show an AOL account, containing emails regarding the account's password being changed. It's unclear if that's really Brennan's email account. Even if it is, it's not clear whether it's a current account or an old one, since the hackers blurred out the email dates.. The hacker wrote that the screenshot showed "a battle" between him and the CIA to take over the email account.
The alleged breach was first reported by The New York Post, which quoted an unnamed "stoner" and "teenage" hacker who described himself as an American high school student who opposes US foreign policy and supports Palestine.
The hacker, or hackers, also claim to have found sensitive documents inside the email account, and tweeted screenshots of one of the documents, which appears to show a fax from the CIA Office of General Counsel.
Motherboard wasn't able to verify whether the documents or the contact list is authentic. The hackers did not immediately reply to a request for comment.
A CIA spokesperson declined to comment, only saying that the agency is "aware of the reports that have surfaced on social media and have referred the matter to the appropriate authorities." A spokesperson for the Director of National Intelligence sent out the same comment.
Two anonymous US officials told USA Today that no classified information was compromised as a result of the hack.
UPDATE, 10/19/2015, 5:20 p.m. ET: Twitter suspended the hackers' account, @_CWA_, on late Monday afternoon.
