You have all probably heard about this bug at the moment. All you need to do is send the following unicode to your friend via iMessage (cannot be normal text):

Code:

effective. Power لُلُصّبُلُلصّبُررً ॣ ॣh ॣ ॣ 冗

To crash their Messages app after restart (so after restart Messages app will fail to open):

Code:

. لُلُصّبُلُلصّبُررً ॣ ॣh ॣ ॣ 冗

View it in your phone browser and copy it over

How it works:

Code:

"It only works when the message has to be abbreviated with '...'. This is usually on the lock screen and main menu of Messages.app. The words effective and power can be anything as long as they're on two different lines, which forces the Arabic text farther down the message where some of the letters will be replaced with '...' The crash happens when the first dot replaces part of one of the Arabic characters (they require more than one byte to store) Normally there are safety checks to make sure half characters aren't stored, but this replacement bypasses those checks for whatever reason."

I actually haven't come across this before.

I have a few victims to try this on.
Much appreciated, thanks.

Have they discussed WHY this works? I heard about this but haven't done any research into it yet

I think it has something to do with the language interpreter? Idk.

I started doing this to kids at my school and it's fucking mobile warfare now

The notification center doesn't handle the unicode in a safe matter and performs an unsafe operation, which causes an unhandled error.

Yep Kizaru is correct. The preview part of the messages app fails to render the unicode and causes an error and forces a reboot.

If you remove the english and replace them with a ., like this:

Code:

. لُلُصّبُلُلصّبُررً ॣ ॣh ॣ ॣ 冗

Their messages and Messenger (facebook) app will crash permanently. Until Apple comes out with a new update, or the person who sent it replaces the preview with a new SMS

Wait so they wont be able to open their messages or messenger app until you send them another message?

Not sure about the code above, but if it's is sent without the period or any normal english ASCII, the user's messaging app can be used again if someone sends the original code (which, by the way, can have pretty much any text in it, not just "Effective Power")

You'd think apple would have thought to fix this before now, lol.

Dude, it's apple. Since when did they give a shit about their customers?
