1. Introduction
On July 21st 2012 at 7AM (Las Vegas time) ESET published
a crack-me for the BlackHat US 2012 edition. Rules were simple: find a valid
couple of serial numbers for a given name before July 26th 2012 2PM
to maybe win $1000 and a BlackCard (that gives you a free entry for either the
next BlackHat US or EU).
