The U.S on Thursday said it's offering a reward of up to $5 million for information on North Korean information technology companies, workers, and related money laundering that it said were generating illicit revenue for Pyongyang.

The reward is designated for information that disrupts the financial mechanisms behind North Korea's alleged exportation of workers to generate revenue, money laundering, and cyber activities that support Pyongyang's weapons of mass destruction program, the U.S. State Department said in a statement.
