The contest results are out. I scored way below my expectation and - after reading a few submissions from the top half of the list - I can't really tell what the reason for it is :-(. (Not that it matters all that much - given that I wasn't eligible for prizes anyway - it's just a matter of pride.)
Anyway, if you are so inclined, read through the submissions. You will find methods that apply to you, weather you are just a sysadmin or somebody who is interested in reverse engineering.
