A Denver TV station demonstrates the insecurity of wireless networks at the Denver Airport: A reporter and a security analyst sat nearby a hotspot user and were able to steal his email. They approach the user and tell him that anyone could do the same. The story says that the reporters got his cell phone number, social security number, and Visa card number. We're curious about why he was sending that information in an email. The story is typically sensational for a local news station but the point is made--users should make sure they have a secure connection like a VPN if they're sending that kind of information. If such security measures aren't available to them, they shouldn't send that information.
