I was fooled into this when his first book was released, "The Art of Deception". I think I read the first three pages and heart sank because it wasn't a book about computer stuff really at all and I started thinking this guy is a fraud. but mostly I was fooled by marketing. (I was 12 at the time). I just remember being very let down by the book and not being a fan of Mitnik for that reason.
The comment section of this post has an underlying anger towards the hi-jacking of the word 'hacker' as it was and is applied to kevin mitnik and thus misunderstood by the public waaaaay too often.
