A new theory has surfaced that downplays North Korea's involvement in the Sony hacking scandal and suggests the people responsible are actually Russian, based on a linguistics study of the leaked emails. Security experts believe the origins of the now-infamous Guardians of the Peace are Russian after analyzing about 1,600 words attached to the Sony emails the hacking group leaked to a variety of media outlets. The words were investigated by Seattle-based cyber security firm Taia Global. 'Our preliminary results show that Sony's attackers were most likely Russian, possibly but not likely Korean and definitely not Mandarin Chinese or German,' the company wrote in a Christmas Eve blog post, according to The New York Daily News.
