On January 10th, COINOTAG News reported that a user fell victim to a sophisticated transaction simulation scam, losing 143.45 ETH, valued at approximately $46,080. This incident highlights the vulnerabilities associated with the Web3 wallet feature that enables users to preview transaction outcomes prior to execution. Designed to enhance transparency and streamline the user experience, this capability can inadvertently introduce risks. Cybercriminals are leveraging the time gap between the simulation and actual transaction execution by setting up phishing websites that manipulate on-chain states immediately following a transaction submission. As the adoption of blockchain technologies grows, users must remain vigilant against such threats and exercise caution during any financial interaction within decentralized environments. Enhanced security practices and awareness are essential for safeguarding digital assets against evolving cyber threats.
