Slashdot points out how the most elaborate security in the world means nothing in the face of a simple social engineering attack:

Well, at this year's Infosecurity Europe, it was revealed that 92% of the 200 attendees surveyed would gladly trade enough information to steal their identities for a chance to win theater tickets. Social engineering at its best. Why spend time writing bots and rootkits when people will give you what you want for a piece of candy or a ticket to see The Pacifier?"

And this was at a security conference :)
