When you think about how an “advanced persistent threat,” i.e., a hacker, works, think of a professional quarterback like the Green Bay Packers' Aaron Rodgers. Smart, capable and most of all flexible, a pro QB will read a defense and exploit whatever weakness it offers. He might look first for a 50-yard TD strike to the split-end running a fly down the sideline. But if the cornerback has that guy covered, he'll look next for the flanker on a cross 20 yards deep. If the safety is blanketing the flanker, the wily QB will take what he can get, either dumping off to a halfback sneaking in front the linebackers in the hook zone 7 yards downfield or, if the tackles are split and he's fleet of foot like Rodgers, running the ball himself.
