The iPhone, regardless of the model, can be blocked by a new message recently discovered, which allows the temporary blocking of the terminals, even if it is running iOS 10.3. This is the fourth bug discovered in recent months for blocking iPhone terminals, but the good part is that now we are talking about something that only does a temporary block, not a permanent one.
In the video clip below you can see the functionality of this bug, which involves sending a text message to iPhone terminals through the Messages application. Upon receipt, the Messages application will freeze for a maximum of 15-20 seconds, after which things will return to normal and the application can be used without problems.
If you send multiple messages to the victim's iPhone terminal, then the device will be blocked for a longer period of time, depending on the number of messages sent. In this idea, you can block an iPhone for a good few minutes if you send several messages to that device in quick succession.
The message that temporarily blocks any iPhone
If you want to do more harm to an iPhone user, well, you can send him the messages when you know that his terminal is blocked, because the problem will be even bigger. In this situation, the terminal will be completely blocked and will require a complete restart to be able to be used by the user, something that does not happen if the terminal is open.
Even in this situation, the crash is one that can be resolved without having to take complicated steps, as is the case with other bugs. Of course, no one would like to have to restart their terminal after several attacks like this, but that's what happens when bugs like this are discovered.
This bug can be exploited in all versions of iOS 10 released by Apple, including iOS 10.3, so you will not be able to avoid it by updating to the latest version. The text message that locks the iPhone in this way can be found here.
