I picked this book up at Hackers on Planet Earth, and got Kevin Mitnick to sign a poster at the same time. The book is a hoot. I've done the spy stuff, it's boring compared to the persistent intelligence shown by these cyber-spooks, a couple of whom I am pleased to know.
I suppose the disclaimer is necessary: this is a novel, for educational and entertainment purposes only. If you want to be cyber-spy, this book strikes me as a great way to start getting hooked. If you are a security manager, be afraid, very afraid…you need to read this book.
