Partial Crypto1 attack

Hello! Everybody here knows about the new "suPPer" card, which is able to auth twice against a legit reader and recover the key used in that transaction.

Which is the theory behind that? Any paper explaining the attack? I'm still waiting for the card to run some tests, but the software only needs two "Nr and Rr" with a nT = 0.... Someone here knows the calculation behind that recovery or rollback?

Maybe, we can just create a piece of soft inside the pMark3 to run this in standalone mode!

Thanks!
