If I'm reading that right, the attack assumes the attacker has (among other things) a private key (IK) stored only on the user's device, and the user's password.
Thus, engaging on this attack would seem to require hardware access to one of the victims' devices (or some other backdoor), in which case you've already lost.
Correct me if I'm wrong, but that doesn't seem particularly dangerous to me? As always, security of your physical hardware (and not falling for phishing attacks) is paramount.
