A new video demonstrates how a fake contact iMessage on the iPhone can render useless.

The attack works through a modified contact. If this contact is sent via iMessage or SMS and opened by the receiver, its iPhone starts to play crazy.

When the message app is exited, the device will work normally - until it is reopened.

Fake contact makes messaging app useless

Then only a white screen appears, which can be seen for a few seconds. Then crasht the app. A reboot does not help in this case.

However, the receipt of SMS or iMessages still works without problems - only the app can not be opened anymore.
