We’ve all been there: stranded in a coffee shop with a dropping phone battery and no connector, only to find a free USB charging station nearby. Relieved, you plug in your device and go about your business, unaware that a potential threat lurks behind that seemingly benign USB port.
That concern is “juice jacking,” a cybersecurity vulnerability that has received enough attention in recent years to warrant an advisory from the FBI. So, what exactly is juice jacking and how risky is it? Here’s all you need to know, along with some recommendations for keeping your mobile devices safe while charging on the road.
What is juice-jacking?
Juice-jacking is when hackers siphon your phone’s data while it is charging. It achieves this using software placed in a kiosk that allows you to quickly charge your phone, or through a cable connected to a charging station. It can do this by plugging the USB charger directly into the socket. USBs, unlike two-pronged plugs, may transmit data as well as electricity.
