mac imessage not sending random messages

It involves embedding the characters in a new contact file and sharing it via iCloud Drive with an iMessage contact, the Guardian reports.

There is, however, a second version of the exploit that works on all versions of iOS 10. It requires the sender to do some legwork involving iCloud and the online Notes app, but once someone receives the text, their handset will freeze without them having to open or read it. Sending the string via a standard message will only affect iPhones and iPads running iOS 10.1 or below. When combined and sent to an Apple device, the sequence causes a handset or tablets to seize up and reboot.

YouTuber EverythingApplePro uploaded a video that reveals the seemingly random string of characters - a waving white flag emoji, a zero, a rainbow, and a hidden Unicode character called 'variation sector 16' (VS16), which can be copied into an iMessage conversation. An iOS bug has been discovered that allows anyone to crash and freeze an iPhone or iPad simply by sending the device a series of emoji.
