Using <\/span>Railgun, a smart contract system that initiates what is known as \u201cZero Knowledge Proof,\u201d the hackers attempted to move the illicit funds through six different exchanges, several of which were notified over the weekend.\u00a0<\/span><\/p>\n

At least two of the exchanges, Binance and Huobi, were able to move fast and freeze at least a portion of the laundered funds.\u00a0<\/span><\/p>\n
