Imagine you’re a business traveler at the airport with a little time to spare before your flight. You fire up your laptop, access the airport’s free wi-fi, log on to your bank account, and pay your credit card bill to free up credit for your trip. Efficient use of time, right? Well, also imagine that you chose the wi-fi access point that looked most likely to be the free airport network from the several options that popped up in your connector – except it’s not. It’s actually a look-alike set up by a hacker, who is now tracking your banking and credit card information, because you’re logged on to his network. Not so efficient, or safe.
