Apple is currently working to fix a bug that allows one person to crash another person’s iPhone simply by sending it a specific text message. The bug affects iOS 8 devices, causing them to crash and restart when a particular SMS message with Arabic characters is received.
The bug crashes not only iPhones, but iPads and Apple Watches as well. After the crash, users have reported not being able to open their Messages App. Apple says that this behavior is caused by a problem in iMessage.
“We are aware of an iMessage issue caused by a specific series of unicode characters and we will make a fix available in a software update,” Apple said in a statement.
There is currently a work around available to get back into Messages. If your phone has been affected, click here and follow the steps.
Apple has fixed bugs like this in the past. Another bug that affected iOS 8 allowed an attacker to crash an iPhone by sending a Class 0 or Flash message, which are usually reserved for emergency notifications. A similar bug also affected iOS 6 in 2013.
