Few things expose your work to greater security risks than latching onto a public Wi-Fi service. Most people don't realize the risks, and even fewer have the ability to perform the geeky tasks that would fix it.

Computer criminals can "sniff" the traffic in a cafe, or set up a fake hot spot that you might innocently log into.

In that scenario, as soon as you get into your online bank account, the evil twin is ready to grab the password.
