Thief Robbed
An attacker stole about $500,000 on Base, and minutes later an MEV bot sandwiched the trade and kept 74% of the loot
According to blockchain security firm PeckShield, an attacker drained roughly $500,000 in USDC from a victim's wallet on the Base network on August 6, 2026. When the attacker tried to convert the loot into wrapped ETH (WETH) through a Uniswap V4 swap, they left the trade unprotected against slippage, exposing it in the public mempool.
An MEV bot spotted the unprotected swap and ran a classic sandwich attack: one transaction right before the thief's trade, one right after, pushing the price against them. The bot walked away with about $370,000 in profit after spending only 3.5 ETH in gas, while the original thief ended up with just 67 ETH, about $129,000, a 74% loss on what they'd stolen.
