Recently, I noticed an interesting event—on January 3rd, four EVM-compatible chains—Ethereum, Optimism, BNB Chain, and Blast—simultaneously experienced wallet attacks, with total losses exceeding $107,000. It may seem scattered, but the underlying logic is quite clear: numerous small theft cases (each under $2000) all point to the same address , which is almost certainly a coordinated attack.

What does this indicate? Phishing attacks or software vulnerabilities may not be isolated incidents but rather a common, cross-chain reusable vulnerability. For hackers to operate on multiple different chains simultaneously is no small feat unless they have something that can be repeatedly exploited.

Although a loss of over $100,000 isn't particularly shocking in DeFi, the danger of this event lies in the trend it reveals. As more users flood into the DeFi ecosystem, security vulnerabilities and attack methods are also evolving. If such incidents continue to occur, the confidence of newcomers entering the space will be seriously affected, and wallet development teams and auditing agencies must take this seriously.

Here are some practical security tips: avoid clicking on unfamiliar links, regularly review wallet authorization records, prioritize hardware wallets for important assets, and enable multi-signature if conditions permit. No one can achieve perfect security alone, but multiple layers of defense can significantly reduce the risk of being attacked.
