MEV 机器人运营商借入 1200 万美元的 WETH 后获利 20 美元

在去中心化金融 (DeFi) 生态系统的世界中，复杂的机器人和算法利用市场效率低下的情况，即使是最先进的策略有时也会产生令人沮丧的结果。

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.

一名机器人运营商在借入近 1200 万美元的 Wrapped Ether (WETH) 后，试图利用以太坊区块链上的代币交换，但失败了，仅获得了 20 美元的利润。

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.

9 月 5 日，区块链分析平台 Arkham Intelligence 在最近的 X 分析中分享了这一事故，揭示了机器人如何部署“三明治”攻击以试图操纵代币交换。

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.

该机器人使用的策略包括检测待处理的交易（在本例中，用户交换了价值约 5,000 美元的 SHFL 代币）并围绕该交易进行两笔交易。该机器人首先在用户交易之前抬高代币价格，然后立即出售，试图从价差中获利。

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.

在这次攻击中，MEV 机器人借了 1197 万美元的闪电贷，希望通过操纵代币互换来快速获利。然而，这笔交易并没有对其有利。

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.

获得贷款后，该机器人执行了 14 笔独立交易，作为三明治攻击的一部分，通过两个去中心化金融 (DeFi) 协议 Aave 和 Uniswap 借入并偿还了约 70 万美元的 USDC 稳定币和 WETH。

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.

Etherscan 数据显示，整个交易在单个区块中得到确认，这表明 MEV 机器人在大约 12 秒内执行了 14 笔交易。

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

尽管交易错综复杂，但不幸的是，MEV 机器人运营商在支付以太坊 (ETH) 费用后仅获得了 20 美元的利润。

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.

该事件发生之际，MEV 机器人在加密货币世界中不断受到关注，网络犯罪分子经常利用它们来利用市场效率低下的情况来获取大量、快速的利润。

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.

据 EigenPhi 称，最近，一个以假名 jaredfromsubway.eth 运行的著名 MEV 机器人通过增强的技术重新出现。这个臭名昭著的机器人在去年初很出名，它已经从加密货币领域消失了，但现在带着先进的功能又回来了。

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.

这些机器人的日益流行也引起了执法部门的注意。今年 5 月，美国检察官指控两兄弟通过一项针对以太坊区块链上的加密货币交易机器人的新计划窃取了约 2500 万美元。

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.

两兄弟分别是来自波士顿的 24 岁的安东·佩雷尔-布埃诺 (Anton Peraire-Bueno) 和来自纽约的 28 岁的詹姆斯·佩雷尔-布埃诺 (James Pepaire-Bueno)，目前面临多项指控，包括串谋实施电汇欺诈、电汇欺诈和串谋洗钱。
