Include Wi-Fi among security risks at airports, FBI warns

Not all potential security breaches at an airport can be captured on a cell phone and posted as a YouTube video.

One such danger lurks in the form of free wireless Internet access offered by many airports throughout the nation and in other public places.

Authorities warn travelers to beware of hackers setting up fake wireless fidelity – or Wi-Fi – connections to steal passwords, credit card and bank account numbers, and other personal information. Experts say the threat is not new, but it's not clear how prevalent it has become over the years because tracking where information was initially compromised in most identity theft cases is often difficult.
