YouTube star EverythingApplePro has published a video today revealing two new methods through which someone could crash iOS devices.
Both methods, detailed in the video below, don't need any user interaction and will freeze and later crash the target's device at the moment a specially-crafted message is received.
The first method is the simplest to carry out and relies on sending a message to a victim that contains a white flag emoji, zero (0), and the rainbow emoji.
At the moment the target receives this message, his/hers device will immediately freeze and eventually reboot in a few minutes.
This bug is a variation of a bug previously discovered by a French researcher and affects devices running iOS 10.0 through 10.1.1.
EverythingApplePro has published an explanation of what he believes is happening under the hood.
The second method is a little bit more complex to reproduce, but works against all iOS versions between 10.0 and 10.2.1.
According to the YouTuber, users have to copy-paste the three characters many times over inside a contact card.
Once they send this contact card to the victim via iCloud's sharing feature, the target's device will crash, even if the victim hasn't manually opened the file.
Apple is expected to release fixes for the bugs. This is not the first time EverythingApplePro has shared iOS-crashing bugs.
