The fault-based attack that we developed in this work exploits

hardware faults injected at the server side of a public key authentication

(see Figure 1.b). Specifically, we assume that an attacker can

occasionally inject faults that affecting the result of a multiplication

computed during the execution of the fixed-window exponentiation

algorithm.

...

To make this attack possible, faults with the characteristics described

must be injected in the attacked microprocessor.

So as soon as you break into one of Blizzard's data centres and figure out how to do this to their servers, the key is as good as yours!

Hehe, you might just copy it from their HD though when you're already there...

Isn't it possible to connect with PseuWow to retail and just get that key?

No, the key is never sent, you can make a client and connect fine with the public key but you won't be able to get the private part needed to make a server.
