The U.S. has placed a $10 million bounty on a North Korean national tied to a notorious cybercrime syndicate, accusing him of infecting health care systems with ransomware and attacking NASA and the U.S. Air Force.

The reward is for information that could lead to the identification or location of Rim Jong Hyok, who is “associated with a malicious cyber group known as Andariel,” the State Department announced in a press release on Thursday.
