According to BlockBeats, on January 10, according to Scam Sniffer monitoring, a user lost 143.45 ETH (about 460,800 US dollars) yesterday due to transaction simulation fraud.
Transaction simulation is a feature in Web3 wallets that allows users to see the expected results of a transaction before signing it. This feature is designed to improve transparency and user experience.
However, the attacker took advantage of the delay between transaction simulation and execution by creating a phishing website to tamper with the on-chain state immediately after the transaction was submitted.
