Just recently noticed this topic, and have been looking a bit into it the past days

It seems the 8 char length has been completely searched if im not wrong?

The PC used to create the password from random.org back in 2015, is that still around, if not maybe the harddrive running the OS is?
Im not familiar with the web response from random.org back in 2015, but maybe something was revealed in the URL about the generation of the password, i think this could be worthwhile to look into, given the BTC amount.
