A good example of why trust validation is important and why social engineering is one of the most difficult threat vectors to protect against. Hacking the human brain to get trust is a lot easier in most cases than cracking a lot of digital defenses (although it seems a lot of people neglect basic digital defense too...). With some companies I've worked for, I've realized how sometimes customer support could be easily duped, because they want so badly to help the person who is obviously having difficulties and paying us so much money... :P
