The Next Web is reporting that a group of iOS developers has been targeted with a series of rapid-fire messages on iMessage, creating a sort of denial-of-service (DoS) attack that crashes the iMessage app. Grant Paul, one of the targeted iOS developers explains how the attack worked: “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,” Paul says. The second part of that, he explains, is that if a user sends a ‘complex’ text message using unicode characters that force a browser to render ‘Zalgo’ text, or simply uses a message that is enormous in size, them the Messages app will eventually crash as it fails to display it properly.
