There's a firmware update that fixes the vulnerability. Kinda moot as long as you do updates.

EDIT: Seems you have to buy a new key for that, but the difficulty of executing the vulnerability means it probably doesn't matter anyway.

Also requires $11k in gear and physical access to the key.

I thought these device's firmware were strictly read only and can't get updates.

Apparently not.

EDIT: It seems they actually are? So I guess if you're at risk of having a national government try to break your security key, you should buy a new one.
