The bureau said in a press release that North Korean bad actors laundered over $60 million worth of ether (ETH) through RAILGUN, a crypto mixing protocol. The FBI claims that some of the laundered ether was later sent to crypto exchanges and converted to bitcoin (BTC).
Although a portion of these funds were frozen, the agency declined to elaborate on the matter. The announcement comes after Binance and Huobi said they had blocked a total of 124 BTC ($2.58 million) stolen during the $100 million hack of Harmony's cross-chain bridge.
According to analytics firm ZachXBT, the attackers transferred 41,000 ETH valued at $63.5 million from the hack through RAILGUN on January 13-14 before consolidating the funds and depositing them on three different exchanges. To do so, the hackers used more than 350 addresses.
