Binance, the world’s biggest cryptocurrency exchange, said it has covered $6 billion of the $6.3 billion stolen from its platform by using company money to buy replacement tokens, after a hack that US officials said was carried out by a North Korean state-sponsored unit known as TraderTraitor. "We had already covered $6B of the impacted amount of the hacked loss," Binance said on X on Saturday, after saying earlier that it had covered 90% of the stolen funds.
