On one side, South Korean spies offer payment for articles critical of the North Korean regime. On the other, North Korean cybercriminals try to steal information and disrupt computers.

Since her days in the State Department during the Jimmy Carter administration, Roberta Cohen has been a leading voice calling for action on North Korea’s human rights abuses.
