A recent spate of prank texts sent to a group of iOS developers has 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.

As reported to The Next Web, iOS app developers iH8sn0w, well known for his jailbreak tool, and Grant Paul were among those targeted by a type of denial of service (DoS) attack that overwhelmed their respective Messages inboxes with a load of automatically-generated transmissions.
The two devs believe the messages to have been sent one after another from the Messages app on OS X, with a simple AppleScript effecting the barrage that prompts a victim to constantly clear notifications and text.
