Researchers from the Georgia Institute of Technology have put together a prototype charger capable of installing malware onto an iPhone. They plan to show their research to the Black Hat security conference in late July. The report said that despite the plethora of defense mechanisms in iOS, the researches successfully injected arbitrary software into current-generation Apple devices running the latest operating system software.

Apparently the problem hits all users are affected and it does not need a jailbroken device nor user interaction. Their charger uses a small onboard computer. In fact it's based on a Texas Instruments BeagleBoard, which retails at $45. While the resulting charger measures three inches square—bigger than your average power supply most people would not spot the difference.
