On June 21, the security agency Dilation Effect tweeted a warning that attackers have recently tried large-scale fake recharge USDT on the TON chain. Dilation Effect's on-chain monitoring system found that a malicious address is deploying a counterfeit USDT token contract, which has the same Metadata data as the official USDT, and has been tested for fake recharge on major exchanges. Dilation Effect specifically warns that many exchanges have just started to support TON chain USDT recharge recently, and the system may not be perfect and vulnerable to fake recharge attacks. Exchanges should strengthen monitoring, especially strict review of large TON chain USDT recharge, to prevent the impact of fake recharge incidents on fund security.
