Airport WiFi may be free, but you might pay dearly

Having free WiFi when you're travelling is great. But should you connect to that hotspot at the airport?

You may find an evil twin out there – not your own but one that still can do great harm. That nasty double often awaits you at your airport, ready to attack when you least expect it. 

That's just one of the findings in a report that assesses the vulnerability of airport WiFi, done not to bust the airports' chops, but to make airports and travellers aware of the problems they could encounter.
