According to Michael Nadeau, founder of The DeFi Report, the MEV bot front-ran the transaction by pulling all the USDC liquidity out of Uniswap v3's USDC-USDT pool and then returning it after the trade was completed.

DeFi researcher ‘DeFiac’ speculates that the same trader using different wallets may have encountered a total of six sandwich attacks, citing “internal tools” for analysis. They add that all the funds originated from lending protocol Aave before being deposited into Uniswap.

Defi研究人员“ Defiac”推测，使用不同钱包的同一交易员可能遇到了六次三明治攻击，理由是“内部工具”进行分析。他们补充说，所有资金均来自贷款方案AAVE，然后再将其存入UNISWAP。

Two of the traders fell victim to the MEV bot sandwich attack around 9 AM UTC on March 12. The Ethereum wallet addresses “0xDDe…42a6D” and “0x999…1D215” were sandwich attacked in transactions that occurred three to four minutes earlier, losing $138,838 and $128,038, respectively.

Both of these traders carried out the same trade in the Uniswap v3 liquidity pool when they executed a large portion of the USDC-USDT liquidity.

There is speculation that these transactions may be related to money laundering.

猜测这些交易可能与洗钱有关。

0xngmi, founder of the crypto data dashboard DefiLlama, said: "If you have NK illegal funds, you can construct a trade that is very easily susceptible to MEV attacks, then privately send it to an MEV bot and let them arbitrage it in a bundle. This way, named you can wash all the money with almost zero loss."

Crypto Data Dashboard Defillama的创始人0xngmi说：“如果您拥有NK非法资金，您可以构建一种非常容易受到MEV攻击易受的交易，然后将其私下发送给MEV机器人，并让他们以捆绑措施索要它。这样，您可以将所有的钱洗净而所有的钱。”
