Recently, while organizing my wallet, I suddenly noticed several tokens marked as high risk in the transaction history. Strangely, I never actively claimed these tokens; how did they end up automatically sitting in my wallet? Even more upsetting, when I checked the authorization management, I found two unlimited USDT authorization records, and I have no memory of when I approved them.

How should I handle this situation? Should I just delete those risky tokens directly? More importantly, is there a way to prevent this kind of situation from happening at the source? Where can I revoke or limit the unlimited authorizations?

Has anyone experienced something similar? I feel there are significant security risks with my wallet and would like to hear the fastest ways to troubleshoot and strengthen security.
