Recently, the Bybit exchange suffered a hacker attack, with approximately 514,000 ETH (worth $1.429 billion) stolen through the manipulation of the multi-signature cold wallet smart contract logic, making it one of the largest single fund transfer events on the Ethereum chain. This incident not only exposed the security risks of centralized exchanges but also sounded the alarm for the security of the Ethereum chain ecosystem.

The hackers distributed the massive assets to 49 addresses and laundered the funds through DEX exchanges, mixing tools, and other means, significantly increasing the difficulty of tracking. Although the security company Beosin promptly marked the involved addresses and activated KYT tools to monitor the flow of funds, the existing monitoring systems still appear inadequate in dealing with such decentralized laundering operations.

Additionally, the incident triggered fluctuations in on-chain staking assets and stablecoins. The stolen stETH and cmETH were batch unstaked or transferred, potentially causing short-term liquidity imbalance in on-chain staking pools. The panic associated with the incident also affected the stablecoin USDe, causing it to briefly decouple from the dollar, reflecting the vulnerability of the on-chain stablecoin anchoring mechanism during extreme events.

This incident once again highlights the importance of blockchain security. Exchanges, project parties, and users need to improve security awareness and strengthen security measures. At the same time, on-chain monitoring and tagging systems also need continuous upgrades to cope with increasingly complex hacking methods. Only through joint efforts can we build a more secure and reliable blockchain ecosystem.
