The FBI says the billions of dollars stolen from Binance within minutes in the biggest crypto heist in history was orchestrated by North Korean hackers. The bureau says this week's attack was tied to “malicious cyber activity” by an entity known as TraderTraitor. That same entity behind a $1.5 billion Bybit hack last year. The FBI said Saturday that it is advising crypto exchanges, blockchain analytics companies and others to block transactions tied to certian addresses to keep the money from being laundered further. Later Saturday night, President Donald Trump said authorities were still learning about the case, however, and added, “We don't know if it was North Korea.”
