- Two hacker groups associated with North Korea, the Lazarus Group and APT38, were responsible for the theft last June of $100 million from U.S. crypto firm Harmony's Horizon bridge, the Federal Bureau of Investigation said on Monday.
On Jan. 13, the groups used a privacy protocol called Railgun to launder over $60 million worth of ethereum stolen during the theft in June, the FBI said in a statement
A portion of the stolen ethereum was subsequently sent to several virtual asset providers and converted to bitcoin, the FBI said.
