After enabling the USB debugging Android, it is OK to have your device connected to your personal computer or you are trying to use the Android Debug Bridge (ADB).

But problems might occur when you plug your device into an unfamiliar USB port like the public charging station. Someone who can access the charging station will get the permission to access your device granted by this mode, and they are able to steal your private information and even push certain malware or virus to your device.
