even a latest hardware wallet. a hacker can simply set up a phished/emulating GUI display to show "error with device. to reset device please re enter your seed" or whatever their error pages look like to get people to type it in.
Are there any hardware wallets that actually ask you to do something like that in any circumstances? If yes, then that's a very dangerous thing to have. So far I've been using only Ledger and the only way to enter seed phrase was directly using the device and not via Ledger Live app so if any message like that pop up, Ledger users should know that it is a fake. Not that it would stop some people entering seed anyway.
You are saying ledger users should know, but let's be honest, if you do not believe it and be careful about it that's fine but how many people would fall for it? I have seen people lose billions of dollars because of silly hacks, and not even hacks I have seen people send hundreds of thousands of dollars to fake twitter accounts as well.
People who act as if they are Elon and tweet underneath and buy likes and retweets so they look at the top, and say "send eth here and I will send double back" and got hundreds of thousands of dollars that way. So it's really all about how people are not aware of what they should in order to not get hacked, nor they know how to spot a scam.
