Unknown transfers

Hello, need help. This is not the first time that my purchased currency, in this case "ETH", has been automatically transferred to another (unknown to me) account.

In December 2024, the same thing happened, immediately after making a payment, after receiving "ETH" in my Uniswap account, after a few seconds it transfers to other accounts, they are different... please, who can, who has faced similar problems, explain how this can be.

Thank you.
