An <button class="define-target" id="mev">MEV</button> bot was exploited after an attacker discovered a vulnerability in its code that allowed anyone to call one of its functions that sold <button class="define-target" id="wrapped-token">w</button>BTC for wETH. Using a <button class="define-target" id="flash-loan">flash loan</button> to imbalance a wETH/wBTC <button class="define-target" id="liquidity-pool">pool</button> on Curve, the attacker then caused the bot to purchase wBTC at its inflated price. They then sold the wBTC for a profit. Altogether, the exploiter made off with 1,047&nbsp;ETH ($1.975&nbsp;million).
