Bybit has already paid more than $4 million to bounty hunters who helped trace and freeze some of the stolen funds.

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.
