Wu said that according to the U.S. Department of Justice, North Korean hacker Rim Jong Hyok has been indicted for participating in ransomware attacks against U.S. hospitals and medical providers. North Korean hackers developed custom tools to target and extort, exfiltrate large amounts of sensitive information, and launder funds to support more attacks. The Department of Justice and the FBI announced the recovery of approximately $114,000 in virtual currency proceeds from intercepting these ransomware attacks and related money laundering transactions. In addition, the U.S. State Department is offering a reward of up to $10 million for information leading to Rim's location or identity.
