MEV Bot 返還 Ronin Network Bridge 流失的 1000 萬美元

8 月 6 日，最大可提取價值 (MEV) 機器人從 Ronin 橋接器耗盡了近 3,996 以太幣 (ETH)，現已返還幾乎所有資金

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.

根據區塊瀏覽器 Etherscan 的數據，8 月 6 日，一個機器人從 Ronin 橋上耗盡了近 3,996 以太幣 (ETH)，現在已返還幾乎所有資金。這表明機器人可能意外地搶先了攻擊。

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.

當 ETH 被返還時，其價值超過 1000 萬美元。該機器人於世界標準時間下午 3:04 返還資金。總共有 3,991 ETH 被發送給 Ronin 團隊，而剩餘的 5 ETH 尚未歸還。

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 團隊在社群媒體平台 X 上宣布返還資金，並表示機器人所有者因發現漏洞而獲得 50 萬美元獎勵。團隊還宣布，只有在修補漏洞並進行審核後，才會允許重新開放橋樑。

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 機器人被編程為複製交易並支付更高的汽油費來首先執行它們（如果這樣做有利可圖）。因此，他們有時會意外地利用協議。例如，如果攻擊者嘗試利用協議但未能支付足夠高的汽油費，MEV 機器人可能會自動複製攻擊並耗盡協議資金。在這些情況下，機器人的所有者通常會將資金退還給受害者，正如本例中所發生的那樣。

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

據報道，被抽走的資金最初價值超過 1000 萬美元。
