Hi all,
it's a pleasure to publish this nicely done tutorial by Gyver75.

This document shows the solution to the "HellRaiser System Util V4". The result is to simply unpack the target and find the right serial to unlock it properly. This CrackMe has not yet a solution, therefore I decided to write this little paper with all the details needed.
The tutorial includes everything you need to follow it and shape your own learning experience.

You can find it here.
