Malware could be installed on the USB port or a USB cable connected to a public charging station which could infect your phone helping attackers track keystrokes and/or steal data. You wouldn’t want an attacker to gain access to your banking app, would you? Since the USB port is used for both charging and data transfer, when prompted on the screen whether you are using the port for charging or to transfer data, choose the former when you are hooked up to a public charging station.
The FBI warns the public about using public charging stations
- Instead of using a public charging station, find a wall outlet to plug your own cables into (carry your own charging gear with you).
- If you’re planning to be on the road, buy a car charger (this is underrated advice that is a very good tip).
- Buy a power bank and make sure you charge it up fully before you leave the house or hotel room.
If you absolutely must use a public charging station, keep your phone locked when charging. If you can charge your phone with the device powered off, that would be even better.
While a public charging station might seem like a sight for sore eyes, especially if you’re desperate to charge your device, keep in mind that by using the station, you could end up giving away access to your phone and allow someone you don’t know to get into your banking app and siphon your hard-earned cash out of your accounts. It’s difficult to go without your phone, especially if on a business trip.
