This is not the point! I really hope these are all FUDs and that Trezor is still very safe. If you can't take a Trezor out with you in order to not be lost, half of the point of owning Trezor goes down the drain immediately. Owning Trezor gave me a piece of mind when it comes to stuff like this, and if this peace of mind is no longer here, you guess.
Not to mention that as we get more and more adoption, ways to steal your coins will evolve just like people are stealing regular wallets today in subways, etc..
These are very serious allegations that need to be sorted out and explained.
Does anyone know is Ledger Nano S in the same possible boat?
Ledger devs have confirmed Nano S is not vulnerable to this exploit due to the Secure Element architecture Nano S uses. However, remember Ledger has taken criticism because they cannot open source the Secure Element due to non-disclosure agreements with the manufacturer. KeepKey CTO thinks their hardware wallet is not affected but are not certain yet: a firmware update for KeepKey may be necessary.
Here is the latest news from Trezor just published on their blog. TL;DR updating Trezor firmware to version 1.5.2 fixes the vulnerability.
