Teen Who Hacked CIA Director’s Email Tells How He Did It:

The hacker, who says he’s under 20 years old, told WIRED that he wasn’t working alone but that he and two other people worked on the breach. He says they first did a reverse lookup of Brennan’s mobile phone number to discover that he was a Verizon customer. Then one of them posed as a Verizon technician and called the company asking for details about Brennan’s account.

“[W]e told them we work for Verizon and we have a customer on scheduled callback,” he told WIRED. The caller told Verizon that he was unable to access Verizon’s customer database on his own because “our tools were down.”

After providing the Verizon employee with a fabricated employee Vcode—a unique code the he says Verizon assigns employees—they got the information they were seeking.
