Seems a made up stories so that you can see people suggestion regarding on wallet cracking things or anything that can help you to hack the wallets contains those balances. Its because if you really hold that huge balance for sure you will never forget the private key of your wallets since who's fool people would forget about the so important details of his wallet with a lot of money there for sure with that a person would be more careful to store on multiple offline items or places so that he can secure his funds.

I guess no one will help you with this since its like you want to do nasty things by to those wallet and no people want to be involve on those kind of activities.
