Block anything iPhone with a simple text message that can be sent from any other iPhone, the video clip below demonstrating the rather embarrassing problem for Apple. This is the second type of attack based on which iPhone terminals can be blocked, and everything can be done even without the recipient of the message opening the message sent by you.
Everything is based on the simple sending of three emoji characters in a message, receiving it on an iPhone leads to the complete blocking of the terminal. As you will see in the video clip below, almost any iPhone is automatically blocked when the message arrives in the Messages application, so everything can be done without the user knowing what happened.
This method blocks any iPhone running iOS 10 - iOS 10.1.1, but newer versions require a different "attack" method. More precisely, those emoji characters must be multiplied and entered into a contact, which you must then share, but the final result will be the same, and the iPhone terminal will be blocked immediately.
Lock ANY iPhone with this text message
Those to whom these messages are sent and whose iPhone terminals are blocked, can solve the entire problem by simply accessing a link, and things will return to normal. Even if the attack methods to block any iPhone are different, in the end the result is the same, regardless of the method used to generate headaches for users.
Here is the technical explanation of the problem:
"What you see in the text is the waving white flag emoji, a zero, and the rainbow emoji. The rainbow flag emoji isn't an emoji in itself, it's made of three characters: waving white flag, a character called variation sector 16 (VS16 for short), and the rainbow. What VS16 does in this case essentially is tells the device to combine the two surrounding characters into one emoji, yielding the rainbow flag (this is similar to how skin tone modifiers work, but not exactly the same). The text you're copying is actually waving white flag, VS16, zero, rainbow emoji. What I'm assuming is happening is that the phone tries to combine the waving white flag and the zero into an emoji, but this obviously can't be done. Usually the phone wouldn't try to do this, but it notices that the rainbow emoji is also there, and knows that it can combine the white flag and rainbow emoji, so it tries."
iOS has more and more bugs of this kind lately, but the Apple company constantly continues to solve them to avoid scandals generated by customers. Of course, this bug will be solved by the Apple company at one point or another, but in the meantime users remain vulnerable to those who want to attack them.
