General Internet use is all the experienced required. This is a fun, gossipy read about Black Hats - aka hackers. This is not an alarmist book. It will take a balanced look at the hacking cases that made the news in the past few years and the people behind them as well as the legislation currently in process regarding hacking, reverse-engineering, cracking, and spam.
This book has will attract an educated, technology-savvy audience, someone who doesn't want to slog through a thousand dry pages on computer security but would enjoy a wide survey of the modern threats we all face in the techno jungle.
