ByBit Loses 70% of Ethereum to Hacker, CEO Confirms
In a revealing livestream, Bybit CEO Ben Zhou announced that his crypto exchange lost approximately 70% of its Ethereum holdings due to a massive hack. This incident reportedly involved around $1.5 billion worth of crypto assets. Zhou cited the loss when responding to questions from viewers. "We normally keep sixty to seventy percent in cold wallets," he stated.
The hack, first reported by blockchain investigator ZachXBT and other prominent figures, involved over 400,000 Ether leaving Bybit’s cold wallet. Speculations suggest that the hackers executed a complicated maneuver, tricking those responsible for the wallet keys into authorizing a fraudulent transaction. Security experts indicated that the hackers may have compromised the user interface or the signers’ computers, allowing them to manipulate the multisig wallet’s smart contract.
Further investigations revealed that the attack traced back to the North Korean hacking group, the Lazarus Group. This notorious group has targeted several major crypto exchanges in the past, raising concerns about the increasing sophistication of cyberattacks in the cryptocurrency sector.
Despite this setback, Zhou reassured clients that Bybit could cover all losses. “All client assets are 1:1 backed—we can cover the loss,” he tweeted. The exchange is currently seeking bridge loans to address an immediate liquidity crunch as users initiate "massive withdrawals."
Though some industry leaders, like Binance co-founder Changpeng Zhao, recommended pausing withdrawals as a precaution, Zhou remained firm on keeping operations normal. In a playful suggestion, BitMEX co-founder Arthur Hayes even called on Ethereum co-founder Vitalik Buterin to consider rolling back the blockchain, referencing a past coordinated action after the DAO hack.
This incident highlights the ongoing challenges and vulnerabilities within the cryptocurrency industry, emphasizing the need for improved security measures as technology continues to advance.
