MEV Bot Operator Walks Away with $20 Profit After Borrowing $12M in WETH

In the world of the decentralized finance (DeFi) ecosystem, where sophisticated bots and algorithms exploit market inefficiencies, even the most advanced strategies can sometimes result in underwhelming outcomes.

A bot operator realized a profit of just $20 after borrowing nearly $12 million in Wrapped Ether (WETH) in a failed attempt to exploit a token swap on the Ethereum blockchain.

On September 5, blockchain analytics platform Arkham Intelligence shared the mishap in a recent X analysis, revealing how a bot deployed a “sandwich” attack in an attempt to manipulate a token swap.

The strategy used by the bot involves detecting a pending transaction — in this case, a user swapping around $5,000 worth of SHFL tokens — and placing two transactions around it. The bot first inflates the token price before the user’s trade, then sells immediately after in an attempt to profit from the price difference.

For this attack, the MEV bot borrowed $11.97 million in a flash loan, hoping to manipulate a token swap to secure a quick profit. However, the transaction did not work in its favor.

After getting the loan, the bot then carried out 14 separate transactions as part of the sandwich attack, borrowing and repaying roughly $700,000 in USDC stablecoin and WETH across two decentralized finance (DeFi) protocols Aave and Uniswap.

Etherscan data showed that the entire transaction was confirmed in a single block, indicating that the MEV bot executed the 14 transactions within around 12 seconds.

Despite the intricacies of the transaction, the unlucky MEV bot operator walked away with just $20 in profit after paying Ethereum (ETH) fees.

The incident occurred as MEV bots continue gaining traction in the crypto world, with cybercriminals often using them to exploit market inefficiencies for substantial, quick profits.

Recently, a well-known MEV bot operating under the pseudonym jaredfromsubway.eth has resurfaced with enhanced techniques, according to EigenPhi. The notorious bot, which was prominent early last year, had vanished from the crypto landscape but has now returned with advanced capabilities.

The growing prevalence of these bots has also drawn the attention of law enforcement. In May, prosecutors in the United States charged two brothers for stealing approximately $25 million through a new scheme targeting crypto trading bots on the Ethereum blockchain.

The two brothers, Anton Peraire-Bueno, 24, from Boston, and James Pepaire-Bueno, 28, from New York, are currently facing several charges, including conspiracy to commit wire fraud, wire fraud, and conspiracy to commit money laundering.
