According to South Korean authorities, North Korean computer experts were tasked with raising money by attacking the servers of popular online games and using automated software to accumulate in-game enhancements they could sell to legitimate players. "In a little less than two years, the police said, the organizers made $6 million. The North Korean computer experts were each required to send at least $500 a month back to the Pyongyang government, the police said. It remained unclear how much of the rest of their profits they pocketed for themselves, given different layers of party and military officials involved in a typical illicit operation. What appeared clear from the case, the police said, was that North Korean agencies, increasingly hamstrung by international sanctions, were exploring any new means to raise cash for Mr. Kim and prove their loyalty."
