That's still very vague, though. How was the initial (src + docs) breach performed? How do they escalate that into a successful social engineering attack, particularly since the breach was known of? Did the targeted employee have unfettered access to all this customer data? Will be interesting to know the fuller story. I'm guessing that's only a matter of time.
