Loss Exceeds $7.5 Million: Analysis of the Honeypot Attack Targeting MEV Bot and Tracking of Stolen Funds
On June 21, Jaredfromsubway.eth, one of Ethereum's most active MEV bots, suffered a sophisticated honeypot attack, losing over $7.5 million in crypto assets. Attackers deployed a complex contract system, including a coordinator, trigger, and fake token/pair contracts, to exploit the bot's arbitrage logic. The core attack trick involved baiting the bot with transactions: small trades appeared normal and consumed token approvals, while larger trades preserved these approvals by using fake swaps. This left the bot with large, unused approvals for assets like USDC, USDT, and WETH. The attacker then drained these approvals in a final step.
The stolen funds—$2.87M USDC, $2.04M USDT, and 1,474 WETH—were consolidated and partially laundered through Tornado Cash. This incident highlights that MEV bots must not rely solely on simulated profits for security. Extra caution is required with unfamiliar contracts or custom wrappers in arbitrage paths, and post-transaction allowance checks are strongly recommended.
