protecting your eth tokens

Hello guys,

There is a new scam you may have heard of. A person reach out to you giving you their seeds and private keys and asking you to help him transfer some tokens (usdt/usdc) by sending gas fee (or more) and promising 50% of the proceeds. Unfortunately, when you send you eth, a smart contract immediately transfers out your eth to some adress. The contact (or bot) is so fast that you can never get back your eth and obviously not the honeypot.

My question is to know how this can be used as a security measure say in a hot wallet to protect your assets. You separate your token from your eth and any eth sent to get your token will be immediately sent to some adress leaving the scammer without its eth. If you send a note with a safe word, then the contract is not executed.

Is that possible? How would you do it?

Thanks you if this a dumb question!
