A feature that allows users to wirelessly sync their iPhones and iPads with iTunes can be abused by hackers to take control of iOS devices in what researchers call a “Trustjacking” attack.

This feature can be enabled by physically connecting an iOS device to a computer with iTunes and enabling the option to sync over Wi-Fi. The user is prompted to confirm that the computer is trusted when the mobile device is first connected to it, but no other approval is required to enable the syncing feature or to access the device over Wi-Fi at a later time.
