More anti chinese propaganda. I'm sure Robert Potter, chief executive officer of Internet 2.0, an Australian cybersecurity company that this entire article is based around has nothing to gain from this kind of hit piece.
When doing so myself, my first thought was: "Well China has a huge population, their absolute number of script-kiddies must be higher", but that wouldn't account for Eastern Block countries (and also the Neatherlands for us). We should also see more bad-traffic from South America and India.
