CIA director, John Brennan's AOL email has been hacked. It was claimed by a high school student with the Twitter account of @phphax. The student cracker forewarns Donald Trump and Hillary Clinton as his next target.

In a report from the Fox News Insider, an American high school student claimed he just cracked the personal email account of the director of the CIA, John Brennan.

The hacker had acquired Brennan's Social Security numbers and other intelligence officials' personal information. He also had the letter of the U.S. government regarding their 'harsh interrogation techniques' to suspects of terrorism.

The teenager said he's been prank-calling the top spy in America since August who recited Brennan's Social Security number.

He also bragged about the stolen documents, including Brennan's contact list. The filched attachments were stored in other 40 emails when he broke into Brennan's account in October 12.

The stoner had also sneaked into the Comcast account of Homeland Security Secretary Jeh Johnson and even listened to the secretary's voicemails. He posted on Twitter the screenshot of the billing page.

The hacker introduced himself in the New York Post as a non-Muslim American high school student. He's opposing the American policy and was encouraged by the unity of Palestinians.

He revealed to the Post that he combined social engineering with his technical skills to trick people from Verizon in order to obtain Brennan's information and to fool AOL to reset the password.

Another tweet from the teenage hacker indicates his next target were presidential candidates Hillary Clinton and Donald Trump. "Hey @realDonaldTrump, was wondering if you would like the #CWA dick? Or you @HillaryClinton, we don't mind. :)"

Six months earlier, it was reported that Clinton has been using her own computer server for emails as a secretary of state.

Despite that, the email security of both candidates must be reinforced to higher standards. This sensitive information may expose state secrets and could soon lead to blackmail and extortion.
