iMessage becomes the tool of a Denial of Service Attack

Apple’s instant messaging platform iMessage works to enabling group chat among  iOS devices and it also works on Apple’s desktop OS X as well. Apple computers are fairly easy to script in order to perform repetitive tasks and targeted iMessage attack. several prominent iOS developers have had their iMessage accounts flooded with messages from at least one person claiming to be part of Anonymous. Using an Apple script, the “hacker” automated the sending of several messages in rapid succession. Back in the old days of instant messaging, it was called scrolling.

The strings of messages would be so large and  that will not be possible to clear the messages and notifications by the recipients  The result is that the Messages app would essentially crash, and that is a Denial-of-Service attack.The problem is that iMessage is typically tied to an email address.

The  problem is that Apple does not have any apparent limits or triggers in place related to how fast messages can be sent. That issue can be further complicated when large strings of “complex” characters are sent, preventing the Messages app from rendering everything properly and crashing the application.For now, the only fix is to disable the Messages application as there is no setting to block specific senders.

The attacks hit at least a half-dozen iOS developer and hacker community members.The best solution is for Apple to act quickly to recognize and then block people who are abusing the iMessage service.
