A new discovery has given spies a powerful new tool to track your every move: Your Android's power consumption. People are calling it PowerSpy.
PowerSpy was developed through collaboration between Stanford University and an Israeli defense research group called Rafael.
While spies in the past might have had to trick you into downloading a malicious app that tracks your GPS and contact list, PowerSpy sidesteps this by tracking you through your battery.
I've already told you about how dangerous many location-tracking apps can be, but at least they give you the courtesy of a warning first.
