Take a look at OUCH!, a monthly security awareness newsletter from SANS:

The July issue of OUCH! explains a common social engineering technique called the tech-support attack.

Overview from the newsletter:
At the heart of many cyber attacks are criminals attempting to fool you out of your money or trick you into giving them your personal information. Common examples of this are fraudulent e-mails, called phishing, that pretend to come from a person or company you trust, such as your friend or your bank. While such e-mail attacks are still a threat, criminals are also calling potential victims on the phone. In this newsletter we explain how such a phone scam works, specifically a common tech-support scam, and what you can do to protect yourself.
Other cyber security awareness resources are available from the SANS Securing The Human Program, so take a look and let us know if you find anything particularly useful.
