i have also read this book. i think it's perfect for anyone who really wants to learn the way of social engineering. i have it somewhere on my computer ill search for it, if i find it i will share it with you guys. yes intrusion is better for people interested in hacking. by the way did anyone else notice the fact that mitnick sounded like he was on the side of the government but really he was talking about examples like he was on our side. why he wrote this book I CLEARLY HAVE NO IDEA WHAT I'M TALKING ABOUT, EVER..
