Yoink Bot Foils $7.8M Ethereum Heist with Front-Running Transaction

A sophisticated MEV bot named Yoink has successfully thwarted an attempted heist of $7.8 million worth of rsETH tokens on the Ethereum network.

The attack occurred on September 15, 2026, within Ethereum block number 25980525. The hacker attempted to drain the funds through a vulnerability in a custom Uniswap v4 module integrated with a Safe smart contract wallet.

Yoink spotted the exploitation attempt and executed a front-running transaction, securing the digital assets before the malicious actor could complete the theft.
