the willingness of an attacker to apply money to the problem. I agree but I think the problem here is that hardware wallets don't give up their hashes easily so the attacker either knows a secret hardware backdoor in which case ciphers are entirely bypassed, or they know how to coax the hashes out of those devices. Has this become a thing? I know some of them are vulnerable to side channel attacks and some of them only use sha256 but I have not seen a simple way to extract the hashes, at least not in the forums I visit. There are a few really cheap hardware wallets that people have reverse engineered the firmware and worked backwards to extract pins but I think that is for specific models. Is there a common attack vector that applies to all the hardware wallets to extract the hashes?
