If your goal is detect password and if u accept bruteforce method yes ; i can proof it.
Then why don't you post it here so everyone knows you are not just talking?
If he could do it he would've already done it and ran with the "Large amount of money" that is supposedly stored on the wallet.
alas, he can't do it.
Guys calm down, im waiting rockyou.txt
Edit : seed is already avaible in unencrpyted wallet, i mean no need to money transfer etc, its just password challange.
Edit2 : i tried opencl with 7 gpu bruteforce ; 1024 iteration sha512 decrypt not efficient even if opencl. Also password not in the rockyou.txt list.
