North Korea is continuing to launch cyber attacks on South Korea this time with game programs infected with malignant codes.
Police say a South Korean man surnamed Cho was arrested Sunday for distributing game programs embedded with malignant codes developed by North Korea's reconnaissance unit.
Cho is suspected of purchasing the game programs in Shenyang, China knowing that they were infected with malignant codes and then selling them back to South Korean game operators.
The software turned hundreds of thousands PC's in South Korea into so-called 'zombie' PC's, transferring some 500-thousand pieces of personal information to North Korea.
Investigators believe it was with this data that the North tried to hack into the main server of Seoul's Incheon International Airport last April.
