(Reuters) - A hacker group associated with North Korea, the Lazarus Group, also known as APT38, was 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, North Korean cyber actors 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.

The FBI said North Korea's theft and laundering of virtual currency is used to support its ballistic missile and Weapons of Mass Destruction programs.

In June last year, California-based Harmony said that a heist had hit its Horizon bridge, which was the underlying software used by digital tokens such as bitcoin and ether for transferring crypto between different blockchains.
