The Federal Bureau of Investigation said actors linked to North Korea were behind the theft of $100 million through a cryptocurrency hack last year.
The FBI said it was “able to confirm” that the Lazarus Group and APT38, two hacking groups linked to Pyongyang, were responsible for the 2022 attack on the so-called Horizon Bridge.
Traders use a bridge to exchange cryptocurrencies between different blockchain networks.
The FBI also said this month that North Korean cyber actors used the Railgun system to launder more than $60 million worth of Ether tokens stolen in a June 2022 heist. Railgun is a system designed to keep people moving cryptocurrency anonymous.
Some of the stolen Ether was sent to several virtual asset service providers and converted to bitcoins, the FBI said.
At the time of the breach, blockchain analytics firm Elliptic said there were “strong indications” that Lazarus was behind the attack. Almost immediately, the hackers tried to move the funds using tools to hide their identity.
The FBI said it continues to “detect and disrupt the theft and laundering of North Korean virtual currency used to support North Korea’s ballistic missile and weapons of mass destruction programs.”
Attackers linked to North Korea have been linked to other crypto-hacks.
Last year, the US Treasury Department accused Lazarus of stealing $600 million from the Ronin Network, the so-called “sidechain” of the popular crypto game Axie Infinity.
