$7.8M rsETH Exploited from Gnosis Safe Wallet via Multicall Flaw

A recent Ethereum wallet exploit has drained approximately $7.8 million worth of rsETH from a Gnosis Safe wallet, highlighting a security flaw in a helper contract.

The issue stemmed from an authorization check in the Multicall component selected by the wallet owner for transaction automation.

An automated bot named Yoink front-ran the exploit and withdrew the majority of the assets, with 2,882 rsETH sent to a separate address.
