I have noticed that social engineering is a big deal now. I understand that hackers and anyone trying to accomplish any objectives can use social engineering to get what they want without giving away their true intentions through the power of a simple conversation. I've also found that it's most commonly used for penetration testing.
My question is, where can I go or what books can I read in order to help add social engineering as part of my skill set? I looked at quite a few books on Amazon but was disappointed to see how poorly they did in the reviews. A lot of the books just talk about famous examples of social engineering and don't really tell what you need to know if you are looking to learn more about it.
