After Sony was hacked and its sensitive information have been dumped on the Internet, the FBI named North Korea as the culprit behind the hack. A new report from Reuters cites an official “close to the investigation” that says the U.S. officials believe North Korea hired foreign hackers from outside the country to hack Sony Pictures Entertainment. According to the source, North Korea doesn’t have the capability to “conduct some elements of the sophisticated campaign by itself.” While they maintain that North Korea is behind the “theft and destruction of data” of Sony Pictures Entertainment, the reports says the U.S. officials are investigating if North Korea really did contract hackers from outside its country.
