The FBI is moving closer to officially blaming North Korea for the attack. As CBS 2’s Chris Martinez reports, some believe this is the new frontier of war.

It’s the future of warfare, with North Korea now thought to have waged the first battle successfully. At the heart of it all: the movie “The Interview.”
