Among the ambiguities is whether the Intel breach was related to the Google Aurora intrusion.
Probably it wasn't -- probably the Intel hack was another in the rapidly growing number of targeted attacks aimed at leading companies.
Not sure whether that's a comfort or not, but it's a fact of life, as witness Microsoft's Steve Ballmer's comment in minimizing the Google intrusions :"We're attacked every day from all parts of the world and I think everybody else is too."
