According to TechFlow, 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.

It is reported that transaction simulation is a feature in Web3 wallets that allows users to view the expected results of transactions before signing. This feature is designed to improve transparency and user experience. The attacker took advantage of the delay between transaction simulation and execution, and tampered with the on-chain status immediately after the transaction was submitted by creating a phishing website and completing the theft.
