Bybit, a popular crypto exchange, is reeling from the massive hack worth $1.5 billion in digital assets. According to reports, the hackers targeted the crypto exchange’s cold wallet, an offline storage system, to steal the exchange’s assets, primarily Ether. On-chain data reveals that the stolen funds were quickly transferred into different wallets and liquidated on several platforms.

As the company struggles with a surge in withdrawal requests, it received over 88,000 ETH (worth around $239 million) from popular exchanges like Binance and Bitget. The fresh crypto transfers from these two popular exchanges boosted Bybit’s liquidity, allowing it serve the customers’ withdrawal requests.
