Mind hacker

Saying briefly, social engineering is the kind of technique that is used to manipulate people. Social engineering crackers use several ways to "trick" people and get the important information. Mostly, these crackers not only study hard about new bugs in secure operating system, also they study human psychology or in other words, tendency of human characteristics.
They are the expert of making good relationships and making situations that people are likely to believe in. Most common technique they use is impersonation; they pretend to be an imaginery person and approach to the target. They act as manager, repairman, new employee and so on, depend on situation. They try to let the target trust them and let the target speak about the information. Social engineer often praise or flutter the target, and show friendliness. Anyway, they make tons of effort for hacking.
By the way, I really want the ability of "trusting people ". Maybe I need to "study hard" like them.
