TechFlow reports on January 10 that, according to Scam Sniffer monitoring, a user lost 143.45 ETH (approximately $460,800) yesterday due to transaction simulation spoofing.
Transaction simulation is a feature in Web3 wallets that allows users to preview the expected outcome of a transaction before signing, designed to enhance transparency and user experience. Attackers exploited the delay between simulation and execution by creating phishing websites that immediately alter on-chain states after transaction submission, thereby completing the theft.
