Is there a way to discover a wallet information from an address?
I'm supposing to know how a person can leak our wallet information.
You mean the personal information of the wallet owner? As far as I know there's no way to find that out unless you used a non-custodial wallet of an exchange and you send your personal information for KYC purpose. And in case that exchanges has been breach, hackers can sell your information to the dark web.
That's why majority prefer to use a custodial wallet, a type of wallet that you have total control of your private keys.
