A group of researchers has demonstrated how to compromise an iOS device with a malicious charger at this year's Black Hat convention in Las Vegas. The malware injection is effortless and hides itself in the same way that Apple hides stock apps. According to Reuters, there is no need to worry since the threat will be neutralized by Apple in iOS 7.
Spokesman Tom Neumayr said the problem was fixed in the upcoming release of iOS 7 and Apple "would like to thank the researchers for their valuable input." The update will warn users with a pop up message whenever the iOS device is connected to a computer. This is important, because in the demo an innocent-looking USB charger was actually a small linux computer in disguise, loaded with malware.
