by KOrUPt on Jun.11, 2009, under General, Reversing
Well, the Defcon CTF 2009 qualifications are over… I’ve decided to do a write up for the Binary Leetness 300 challenge 
.
Feedback appreciated!
Note: your anti-virus may detect the below archive as infected, it contains the b300 binary, which is packed. This is a false positive, I recommend you disable your AV.

I’ll be posting a more in-depth overview of my experience at the quals shortly.
Enjoy!

So, perhaps a coincidence… But turns out that on the day of this write up being posted, it received exactly 300 hundred views… I say ‘conincidence’ because this in the Binary Leetness _300_ challenge :p.
So, 300 views… Surely someone has some feedback?
