NCK Brute Force

This is a theoretical exploit which involves brute forcing the NCK from the seczone the CHIPID and the NORID

Feasibility
Given that NCKs are 15 digits long, the keyspace is log(10^15)/log(2)~=2^50 This would be searchable if all the cryptography used was symmetric. But the algo is TEA(RSA(token), NCK+CHIPID+NORID). So that inside RSA has to be done. A modern machine can search the 8 digit keyspace in about 5 minutes, which means we need a couple orders of magnitude speed increase to consider 15 digit.
