To put things into the simplest terms, hardware wallets have never been hacked remotely (assuming no attacker ever got their hands on it in transit) due to the way they were designed. Things could easily change in the future
You think? I'd hate to live in a world where a hardware wallet could be hacked remotely, as in if it's sitting in my safe not connected to any device. Hopefully that will
never become possible, but the pessimist in me kinda sorta believes that it could happen.
My pea-brain understanding of hardware wallets is that the device itself is needed to sign transactions and that's it. All the coins are stored within the seed phrase--but of course if someone gets their hands on that, they'd have the ability to do anything they wanted with them. Someone correct me if I'm wrong, because I'm not a tech guy by any means.
The most important thing I've learned with my Ledger is to keep that seed phrase safe. I could flush that beautiful Ledger down the toilet, but I'd still have access to my coins as long as I had the phrase. But the problem is that the thing on which the seed phrase is written down is subject to everything else that can be stolen or destroyed--theft, fire, whatever. That's the only way I can think of that a hardware wallet can be "hacked" short of a keylogger or some sort of malware in the mix.
