The F.B.I. has confirmed two hacker groups with North Korea links, the Lazarus Group and APT38, were responsible for the theft of $100million from Harmony’s Horizon Bridge.
The groups used a privacy protocol called Railgun to launder over $60m worth of Ethereum stolen during the theft, according to an F.B.I. statement.
A portion of the stolen Ethereum was subsequently sent to several virtual asset providers and converted to Bitcoin.
North Korea’s theft and laundering of virtual currency is used to support its ballistic missile and Weapons of Mass Destruction programs.
In June 2022, Harmony said that a heist hit its Horizon bridge, which was the underlying software used by digital tokens such as bitcoin and ether for transferring crypto between different blockchains.
