Why is BIP38 involved here? From what I remember a password protected wallet.dat basically encrypts more or less only the private key stuff with AES. I may lack knowledge here though as cracking wallet.dats is not my business. I'm more just curious and have fun to broaden my crypto knowledge.

Has anyone tried to load this wallet.dat into Bitcoin Core to check which addresses claim to hold the funds and if a blockexplorer actually shows these funds? I admit, I haven't tried yet because I don't believe this is a legit and valid wallet.dat (well, likely 99.999% of publicly available wallet.dats are manipulated scams).
