A critical vulnerability in the operating system of the iPhone and iPad allows a certain set of characters, including symbols and letters of the Arabic alphabet, lock the devices.
The bug, which looks more like a backdoor (one gap left on purpose, on the sly for some developer) has the power to halt the messaging application and, in some devices, reboot the system.
The message behavior is very strange. The device that sends restarts automatically. Already receiving, lock. Even after restarting, both the machine that sends as what are received without access to messaging app.
The only workaround is to receive another message, which take the notifications area of the grim message. The condition for locking happen is that the apparatus is with the screen off, the lock screen or home. If you have the app open messages, just catch it.
Not to spread the problem, not reproduce the message in its entirety, but it begins with the word “Power”, followed by a few spaces and a strange unicode character.
Apple has He issued a statement acknowledging the problem and said working on a solution.
If your phone has received the evil message, there is a very complete tutorial on Apple Byte, which helps resolve the issue.
It is worth to pay attention to the configuration icon to update the system so the fix is available.
