MEV Bot 返还 Ronin Network Bridge 流失的 1000 万美元

8 月 6 日，最大可提取价值 (MEV) 机器人从 Ronin 网桥耗尽了近 3,996 以太币 (ETH)，现已返还几乎所有资金

A bot that drained nearly 3,996 Ether (ETH) from the Ronin network bridge on August 6 has returned nearly all of the funds, according to data from block explorer Etherscan. This suggests that the bot may have accidentally front-run the attack.

根据区块浏览器 Etherscan 的数据，8 月 6 日，一个机器人从 Ronin 网桥耗尽了近 3,996 以太币 (ETH)，现已返还几乎所有资金。这表明机器人可能意外地抢先了攻击。

At the time the ETH was returned, it was valued at over $10 million. The bot returned the funds at 3:04 pm UTC. A total of 3,991 ETH was sent to the Ronin team, while the remaining 5 ETH has not yet been returned.

当 ETH 被返还时，其价值超过 1000 万美元。该机器人于世界标准时间下午 3:04 返还资金。总共有 3,991 ETH 被发送给 Ronin 团队，而剩余的 5 ETH 尚未归还。

The Ronin team announced the return of the funds on social media platform X and stated that the bot's owner was being rewarded $500,000 for discovering the exploit. The team also announced that it will only allow the bridge to be reopened after the vulnerability is patched and an audit is performed.

Ronin 团队在社交媒体平台 X 上宣布返还资金，并表示机器人所有者因发现该漏洞而获得 50 万美元奖励。该团队还宣布，只有在修补漏洞并进行审核后，才会允许重新开放桥梁。

MEV bots are programmed to copy transactions and pay a higher gas fee to execute them first if doing so is profitable. For this reason, they sometimes accidentally exploit protocols. If an attacker attempts to exploit a protocol but fails to pay a high enough gas fee, for example, an MEV bot may automatically copy the attack and drain a protocol of funds. In these cases, the bot's owner will usually return the funds to the victim, as has happened in this case.

MEV 机器人被编程为复制交易并支付更高的汽油费来首先执行它们（如果这样做有利可图）。因此，他们有时会意外地利用协议。例如，如果攻击者尝试利用协议但未能支付足够高的汽油费，MEV 机器人可能会自动复制攻击并耗尽协议资金。在这些情况下，机器人的所有者通常会将资金退还给受害者，正如本例中所发生的那样。

The drained funds were initially reported to be worth over $10 million.

据报道，被抽走的资金最初价值超过 1000 万美元。
