Defcon CTF 2009 Trivia 400 write up

Filed under: General, Reversing — Tags: , , , , , , , , , , , , , , — KOrUPt @ 18:12

Seems someone took the time to do a write up for this years Defcon Trivial Pursuits 400 challenge :D .

Let me start by saying me nor my team take any credit for this write up, it’s unclear as to who the author is but my guess is ADC of Loller Skaters produced it? Please correct me if I’m wrong in this assumption.

The write up can be found over at Pastie:

http://pastie.org/510841

I’ve also mirrored it locally just incase, it can be found here:

http://korupt.co.uk/defcon/T400Writeup.txt

I strongly recommend you view the above write up within a web browser(preferably Firefox).

To the author of the above guide, very nice work :) . My team and I didn’t manage to solve the T400 challenge during the qualification round. If you’d like me to update the above links please leave a comment and I’ll do so at the earliest opertunity.
