What about the hardware in the new Nano X compared to the Nano S. Did they make any significant changes in the secure element and the storage of private keys? Can the new device be considered safer in any way compared to the S model? Does anyone have some more info on that?
they upgraded to a newer secure element but both are CC EAL5+ certified (the highest level for penetration testing) so it's unlikely to make much of a difference.
if anything, using bluetooth could open up new attack vectors---i'm mainly thinking about privacy since the bluetooth stack can transport pubkeys and addresses.
