Researchers from the Georgia Institute of Technology have successfully found a way to sneak malicious iOS apps past Apple’s strict App Store review process that is designed to prevent such software from making its way onto our devices.

The technique used a seemingly innocent app called “Jekyll” that could be updated after approval to carry out harmful actions without triggering security alarms.

Thanks to Apple’s strict software approval process, iOS devices are generally considered some of the most secure. But you might want to be careful about where you plug them in for charging. Researchers at the Georgia Institute of Technology have developed a modified charger capable of installing malware onto any device running Apple’s latest iOS operating system.

A research team from the Georgia Institute of Technology claims to have discovered a keyboard keylogger attack that is performed using an iPhone’s accelerometer. However, the situation has to be so precise — and is so unlikely — that if you’re a victim of this attack you really are one of the unluckiest people on the planet.
