This is an utterly useless, disorganized mess of a book.
He first goes into some history, definitions, and skills you need to start hacking. Then he goes into types of hacking attacks, making a hacking plan, and then dives into a few specifics (sort of).
The entire book is extremely vague. Even when he mentions specific tools, the presentation is a disjointed pile of garbage that even an experienced computer nerd couldn't wade through. Worse yet, some of the software he recommends trying does not exist or leads to some shady websites that are obvious scams.
In addition, nearly all of the automated tools he mentions do not actually work on today's devices, yet he completely ignores this fact and sells them like this is going to let you grab all the files off of any phone in the world.
90% of this book is discussion on useless topics loosely related to hacking, and the other 10% is equally useless information on using outdated and broken tools.
