Affected are Ledger HW.1 and Ledger Nano, attack requires physical access to the device.
Company has confirmed the problem:https://donjon.ledger.com/lsb/017/
Similar destiny is going to happen to all their discontinued and forgotten devices in few years, including ledger nono S.
No more security updates means that individual coin apps will be soon unusable in older devices.
And lastly, now that they found the issue, would you really want to give more money to ledger for another product or try another brand?
I think that I saw Ledger is sometimes sending customers model S if some of their older models stop working and have no support.
Obviously there is no way to confirm this, but I saw this information posted on their reddit channel before.
The moment these wallets were discontinued and their support ended, was the time people should have stopped using them. It's the same as with Windows XP that someone mentioned above.
It's not the same thing with windows XP and discontinued hardware wallets, but I wouldn't use both of them for different reasons.
I could probably still use Commodore 64 or Spectrum computer for small offline work and retro gaming, but not for anything serious.
Old hardware wallets should not hold any seed words in them, and safest thing would be to smash them with hammer and recycle.
