It is really difficult to protect our personal information in this society of network. Smartphones are an important tool for us to communicate with others. And we often share the plug with others in everyday life. Traveling becomes more and more convenient for us because there are many USB outlets so that our smartphones can be charged in public places such as stations, airports and libraries. Do you have any idea that these USB outlets can lead to data breaches?
Many users are unaware of the risks associated with sharing plugs or using USB outlets. The charging cable is also a data cable. After plugging into the USB outlet, it allows the device behind the USB outlet to access the data on the phone, and the user has no idea what is hidden behind the USB outlet. It can be a computer or hardware device that communicates with the phone to obtain all information from the phone. In this condition, all data on the mobile phone is visible to the device behind this USB outlet.
To prevent such kind of data leakage, you’d better take a power bank or charger with you. Carry your own power adapter and plug it directly to an electrical outlet.
But there are times when you are away from home, the phone has run out of power and you don’t have a power bank or charger. So sharing plug is your only choice. You should do something to decrease the risks of data leakage.
How can the risk of data breach be minimized?
1. When the mobile phone is connected to a USB outlet, any permission request required shall be refused. (including USB debugging and device trust)
2. Turn off the device while charging.
3. Use a cable that only charges and does not transmit data.
4. Put on a USB condom for charging.
If you want to protect yourself from data breaches while surfing the Internet, you can use a VPN service.
