What could go wrong? Plenty.
In addition to providing an electrical current, phone charging cords can send and receive data. That free USB charging hub at an airport, hotel or any other public place may not only charge your phone.The USB charging hub could be connecting to your phone and copying your contact list, email and text messages, voice mail, photographs and videos. It can also copy passwords, banking information and any other information stored on your phone.
