Bizarre Link Sent To iOS & macOS Devices Will Cause Them To Crash

A Twitter user by the name of Abraham Masri has apparently discovered an exploit that looks like GitHub link on the surface, but it crashes Messages on both macOS and iOS. It’s been dubbed the “chaiOS” bug.

PLEASE NOTE: While I did repost the link, this is a use at your own risk sort of thing. 

I tried this on my test iOS device and got mixed results:

  • In some instances, sending the link would cause both the sender and recipient’s device to respiring or cause the Messages app to instantly freeze and crash.
  • Reentering the thread would cause the Messages app to crash again and again, making the only viable solution to regain access to that thread to delete it and start a new one.
  • I am unable to reproduce this on the latest 11.2.5 iOS beta.

It isn’t known if Apple will put out a mitigation for macOS. But for you, you may want to avoid clicking on any links that you get in messages.
