Ethereum Feature May Have Enabled Faster Theft of $2.5B During Binance Hack
An Ethereum upgrade called EIP-7702 included a feature that may have made it easier for the Binance hacker to drain approximately $2.5 billion once they had initial access to the exchange's systems. The feature was not the cause of the original hack but amplified the damage by giving the attacker new permissions to move stolen funds more quickly. Security experts are now reviewing whether this upgrade introduced unexpected vulnerabilities that could be exploited by other attackers. The discovery highlights how changes to blockchain technology can have unintended consequences even when carefully planned. This incident demonstrates the complex interactions between different blockchain systems and why security audits must consider these cross-chain effects.
