For a nice read, try this book:
The Art of Deception
Kevin D. Mitnick
This book discusses a totally different form of hacking: social engineering. It has really nice examples of how people (including Kevin himself) pulled off amazing hacks and heists. If you think your network/application/company is protected against hackers, because you’ve got the best technology money can buy: this book is for you. You forgot about the human factor.
Think of the movie “Catch me if you can” and substitute bank-fraud for hacking and you’re pretty close on what the book discusses.
