Dubai-based crypto exchange Bybit has suffered one of the largest hacks in digital currency history, losing approximately $1.5 billion worth of Ethereum. The security breach led to a "bank run" exceeding $4 billion in withdrawals. Bybit CEO Ben Zhou assured users that the exchange remains solvent and has secured a loan to cover the loss. Investigations point to North Korean hackers, while Bybit explores security measures and alternative wallet solutions to restore confidence.
