Sony Pictures Entertainment is investigating to determine if hackers working on behalf of North Korea might be responsible for a cyber attack that knocked out the studio's computer network earlier this week, the technology news site Re/code reported, according to Reuters. The attack occurred a month before Sony Pictures, a unit of Sony Corp, is to release "The Interview." The movie is a comedy about two journalists who are recruited by the CIA to assassinate North Korean leader Kim Jong Un. The Pyongyang government denounced the film as "undisguised sponsoring of terrorism, as well as an act of war" in a letter to U.N. Secretary-General Ban Ki-moon in June. -- SPA 20:56 LOCAL TIME 17:56 GMT تغريد
