The Hermit Kingdom's hackers are under scrutiny. Last week, a number of Sony Pictures films, including the unreleased Annie, Mr. Turner, Still Alice and To Write Love on Her Arms, were leaked online, and U.S. law enforcement agencies are investigating whether North Korea is behind the hack. The attack knocked off the company's computer system with similar tools used last year in a hack of South Korean TV stations and ATMs. It was claimed by a group called Guardians of Peace, and it may be connected to a Sony film called The Interview, which revolves around a plot to assassinate North Korean leader Kim Jong-un, and will be released this month.
