iMessage "Denial of Service" Prank Crashes iOS Messages App
According to the folks over at The Next Web, a recent prank played on a group of iOS developers seems to have revealed a limitation in how Apple handles data sent through its iMessage service, which in some cases can crash the app if the incoming message is too long or contains overly complex characters.
Popular developers such as ih8sn0w and Grant Paul were among those targeted by a specific type of denial of service (DoS) attack that overwhelmed their Messages inboxes with a load of automatically-generated transmissions. The two developers believe the messages that were sent to them via the Messages app on OS X with a simple AppleScript affecting the barrage that prompts a victim to constantly clear notifications and text. According to Paul:
What’s happening is a simple flood: Apple doesn’t seem to limit how fast messages can be sent, so the attacker is able to send thousands of messages very quickly.
The real issue that arises with the attack is with the long and/or complex messages that are received. Depending on what is sent, Messages on iOS can crash because it can’t process and display the massive amount of data correctly. According to the developers, the app will force itself to close and won’t re-open because it can’t properly render the text. As of right now, there isn’t any surefire solution to remedy the crashed Messages app.
The publication suggests "playing around with sending a regular message, then locking the phone and activating the message notification until you’re able to time it right to delete the message thread that’s causing the problem. One thing to note is that if the attacker gets a hold of a user’s iMessage handle, the only option may be to disable the account temporarily. If a user’s phone number is compromised, iMessage as a whole may have to be turned off.
The identity of the attack behind the attacks remains unknown at the moment but the messages appear to have originated from a Twitter account used to sell UDIDs and provisioning profiles. Disposable email accounts were being used to send the spam, making it difficult to simply block the culprit as they can simply open another and continue to bombard you with messages.
Apple hasn’t responded to the issue just yet but we’re hoping they will soon.

Can u sign into messages on
Osx to clear the problem messages to make it work again?
I use a different id on each computer/ device for iMessages so I've never really tried...

Could you disable iMessages from external contacts via Settings->Notifications->Messages to prevent this attack?

I was apart of a huge iMessage group chat consisting of about 6 people. Earlier this week, when everybody happened to be off from work, everyone started iMessaging like crazy and my phone actually crashed. I actually thought to myself "I guess iMessage cant handle that much info coming through at once. Just a coincidence i suppose.

The sad thing the only way i can see to stop this would be to limit the outgoing iMessage amount which could interfere with someone actually sending lots if real messages.

scroll down a bit and select 'More package sources' from there select Modmyi and you're good to go.....now if you want
to use ZodTTD repo again then you'll have to do the reverse.
hope it helps
