@Misleading.
It was a known exploit as per the contest rules, and it having been a known exploit would have been worked on for a long time beforehand, just an opportunity arose to use that research.
As well as this was in a controlled environment as to allow the rules to be followed, it's true in real-world situations, that such rules don't exist, but this was a contest to determine which platform could be compromised via *known* exploits, if you were to perform this contest on the internet, people would use unknown exploits no doubt, therefore invalidating the contest.
Overall, this contest is a good display at how proactive the different platforms are in creating patches for *individual* *known* exploits.
