The real surprise is to learn that they have computers, email, and networks in North Korea. Imagine trying to do anything with computers when you do not have power for the whole day. I wonder if those new Dell laptops with 14 hour batteries are selling well there? Wait, they cannot buy Dell computers in North Korea. Just what kind of computers do they have?
Evidently they have enough computing power to contrive custom Trojan Horses and send them to army officers in South Korea. Despite South Korean claims that they are not hackable they have told officers to avoid storing sensitive information on their computers. Hah!
