Express News | DEX Aggregator 0x: Sharp Rise in Malicious Uniswap v4 Hooks Deceiving Users Through Price Discrepancies Between Quotes and Settlement

On September 15, DEX aggregator 0x stated on platform X that year-to-date, it has facilitated 81.92 million transactions with a trading volume of $42.67 billion, approximately 70% of which involved Uniswap liquidity. Meanwhile, we receive dozens of requests each month to review and integrate v4 Hooks. Consequently, we have encountered both well-designed and flawed implementations. Recently, however, we have even begun to observe malicious Hooks. Over the past few weeks, 0x has identified a concerning surge in malicious Uniswap v4 Hooks. These Hooks are designed to display a transaction at one price during the quote request phase but execute it at a different price during actual settlement. While the attack vectors of malicious Hooks vary, the outcome is invariably the same: stealing funds from users by deceiving aggregators, wallets, and trading applications.
