North Korea's Cyberwarfare

According to Jang Se-yul, a person who had formerly worked for the North Korean government before defecting, the nation has an established squad for cyberattacks. This squad, called Bureau 121, conducts cyberattacks on any nation or group that North Korea considers their 'enemy.'  Jang believes that this group was behind the Sony attacks earlier this month, and that they have attacked before. South Korea had reported cyberattacks before, which was supposedly traced back to North Korea. 

People now realize that their views of North Korea are far different from how they really are. People see the country as a dictatorship wracked by poverty, but in fact, they at least have enough money to train these so-called 'cyber warriors.' 

It brings the question: what else is North Korea hiding? Maybe they are truly more advanced than we thought before, and that their threats aren't empty. Their nuclear threats may have no substance to them, but if they have the capability to bring an entertainment empire like Sony to its knees, who knows what they could attack next.
