Debrief: Cracked Ethereum wallet - a beginners approach

[FleetwoodAMAC]

Hi,

I'm having difficulty creating rules for a mixed password.

I believen it is between 10-12 characters

I know the first letter is Uppercase, and the last is a special character. The rest are upper, lower, numbers and characters.

Is there any way to create rules for something like this?

I'm trying to crack an -m 15700 eth and clearly confused.

Thank you!
