So in September of this year, Cloud Passage ran a sort of ctf type contest with a cash prize and this guy named Terrence (mentioned in the article) exploits a minimally setup cloud server in under 4 hours. It's pretty funny because he's just this lonely little 28 year old undergrad who's worked for a computer company for about a year and he just absolutely blows the competition out of the water.
