One day, in an afternoon, when you are relaxing in your home, you get a call from HSBC and they tell you they are rechecking credit cards. “Could you please tell me, your credit card number?”. Just without thinking much, most probably what you’ll do is tell it. And your personal details, etc. So, next month when the bill comes, you know someone has illegally used your credit card.

Basically, that’s social engineering; Gathering information by talking to the people. This is easier than hacking, and probably more effective. Because in a computer system, system admin can patch the vulnerable products but there is no patch for human stupidity.

Just wanted to tell you, “Beware of Social Engineers”.
