At [DeepSec] last year i had the pleasure of hearing Ivan Krsti? speak. While some of his arguments had (small) holes in them (which the audience were quick to pounce on), he raised the ugly fact that people like me like to ignore.. That some of us spend a lot more time thinking of elaborate ways to break stuff than we do designing less breakable stuff.. I think for most security “breakers” its an argument that sometimes hits hard, and makes you wonder if you should be refocusing your efforts..
