From whole world of hacking and famous names of hacker, Kevin is rather the interesting one to me personally.
He is fully aware of the power of social engineering and social networks. This topic emerged to me when I was on elementary school and due to family situation, we moved quite often.
And every time I was the new kid in the class, I have noticed similar patterns in other´s kids behavior.
Later on I have noticed same patterns at college and even in business world.
Social engineering is still most powerful hacking vector, whenever human factor is involved.
