Really enjoyed his book as well. While all the tech stuff was cool, what really impressed me was how much he was able to do by just acting confident and working the people around him. Like calling up companies and asking for information (with just enough insider knowledge) and getting what he needed. The social aspect was really interesting to read about!
Which book? I've never heard of him before today but after reading a few articles I'd like to check out one of his books. Googling sends me quite a few results.
He has several, I’ve read “The Art of Deception” and “The Art of Intrusion” which are both fantastic and interesting reads. He has another in the “Art of…” series and possibly others too.
