This Is How The FBI Linked Sony Hack To North Korea

FBI Director James Comey has revealed they have definitive evidence proving that North Korean hackers were behind the attack on Sony Pictures.

Comey revealed to an audience at a security conference that some of the emails sent by the hackers were through internet connections 'used exclusively' by North Koreans.

The director went on to reveal that because the hackers had 'got sloppy' the FBI were able to pinpoint the exact origin of the emails.

Other US government organisations have gone even further with the Director of National Intelligence James Clapper naming North Korea's Reconnaissance head General Kim Youn Choi as the official that ordered the attack against Sony Pictures.
