"On Thin Ice" a Book keeping you safe Online
The chapter is a great read. I've dabbled in Tor and looked around a bit and the potential is pretty scary. I agree that the Social Engineering part is probably the most effective and subtle way of hacking. Kevin Mitnick was able to exploit the helpful nature of people to get access to systems and paid for it the hard way. Even though he didn't steal anything of value he showed the potential for this type of manipulation.
Technology, like diseases are getting more widespread and dangerous every day and makes you stop and think about what the future holds. I recommend the book to those looking for more information on how to keep yourself safe in the online world.
