Social Engineering and DEF CON have always gone hand-in-hand, but after some of the things I’ve seen on the floor this weekend, it would seem that people have forgotten this. I’m willing to bet the growth of DEF CON over the last few years has only increased the pool of people completely unaware of Social Engineering, both passive, direct, and indirect. The growth of the social engineering community has erased that barrier of awareness of social engineering, and it’s good for researchers and hackers, bad for criminals.”]
