Just come it to my mind. is it possible? to get hook into your wallet and send some to another wallet?

I assume you mean hack into another persons wallet and send it to yours ? That's a really strange question to be asking. No you can't hack someones wallet , it doesnt work like that. You dont hack someone directly you will need to try find a way to get their private key or passwords or F2A verification or some other means.
I don't think he meant that, what I understand on the topic is that is there a possibility that one person can hack into our wallet and change all the information to steal our account or just simply steal our bitcoins.
