A single character can crash iPhone if it simply pasted in the text field, received as a message via apps like Facebook Messenger, WhatsApp, etc can crash the application or the entire device.
This bug can be exploited very easily, all you need is to send them a single Telugu character which is spoken in India by about 70 million people. You can find the Character in Question below.
If you received the character with an application like WhatsApp, Twitter, Facebook, etc the application will crash in the continuous loop each and every time you try to start the application.
The worst part is if someone sends the text to you and the iOS tries to show that in notification leads to the whole system crashes on iPads, Macs, Apple’s iOS Springboard, iPhones, Apple Watches, and Macs.
Seems the Beta version of iOS 11.3 is already immune to the attack and the users of Telegram and Skype are not affected.
