The attack uses custom electronics hidden inside what appears to be a USB charging station. As soon as you connect a vulnerable phone to the appropriate USB charging cord, the spy machine splits the phone’s video display and records a video of everything you tap, type or view on it as long as its plugged in. This includes PINs, passwords, account numbers, emails, texts, pictures and videos. There is no widespread risk of this happening, but it’s still wise for smartphone users to take care over where they plug in their devices.”]
