According to Bybit's holdings, that amounts to $1.5 billion in cryptocurrency that was stolen from Bybit and its customers, making this the largest ever cryptocurrency theft. However, as Molly White of Web3IsGoingGreat points out, the hacker can't exactly cash out $1.5 billion in Ethereum, because an amount that high would crash the value of ETH.

Researchers spot the stolen funds moving through cryptocurrency wallets that were used in earlier heists attributed to North Korea's Lazarus hacking group.

Cryptocurrency exchange Bybit said last week hackers had stolen digital tokens worth around $1.5 billion, in what researchers called the biggest crypto heist of all time. Bybit CEO Ben Zhou said the crypto was taken from a "cold wallet" - a digital wallet usually stored offline and so supposedly more secure - that was used for ether tokens.
