The following is a complete recording of Mikko Hyppponen's opening keynote to the AusCERT 2012 conference. Mikko is the chief research officer for the Finnish antivirus firm F-Secure.

It takes him a few minutes to pick up steam, but I definitely recommend sticking with his talk. It starts out good and winds up fascinating. The title of his talk is The Enemy, and in it he examines three groups of attackers -- Criminals, Hacktivists and Nation States. It sounds like well worn material, but Mikko's take is definitely worth listening to.
