Fueled by the fastest and most pervasive Internet connections on Earth, online gaming is now a national obsession in South Korea. But while millions of people are engrossed in virtual warfare, their computers have also become very real battlegrounds, with North Korea launching Web-based assaults that disable banking, transportation, and Internet portals in the south. After a discussion of gaming addiction in South Korea, this program talks with key defectors about North Korea’s agenda of cyber attacks. Viewers meet Kim Hung-kwang, an architect of the cyber-warfare program who spent 20 years training hackers in Pyongyang; Park Sang-Hak, the son of a North Korean spy-defector and number one on Pyongyang’s hit list; and Jang Se-Yul, a former North Korean colonel, who touches on the implications of hacking for the West.
