Bug originally found by Preston159

The following message will freeze an iPhone when received as an iMessage and displayed as a banner notification. Use responsibly.

This bug appears to only affect through iOS v10.1.1. 10.2+ does not seem vulnerable.

  1. Click in this text area
  2. Select all (ctrl+A or cmd+A) and copy
  3. Paste in Messages on Mac or in new note on icloud.com to send from your phone

You will not be able to copy/paste this text on your iPhone. You must create a new note from icloud.com, open that note on your phone, and share via messages, or send via iMessage from a Mac.


Filip (EverythingApplePro) found a way to make this bug affect iOS 10.2+ upon receipt. Download this contact file and send it via iMessage. You must save into iCloud drive before sending if on iOS.
