An exploit has been discovered that causes iPhones and iPads to reboot when sent a string of malicious text.The bug was found on Reddit, reports 9to5Mac, but the exploit has since been confirmed by Apple. If the offending 75-byte sequence of unicode characters are sent via a text message, and appear on a user’s iPhone lockscreen, the device will crash and reboot.
There’s a bug in Apple’s iOS 8 that allows nearby attackers to send apps—and in some cases the iPhone or iPad they run on—into an endless reboot cycle that temporarily renders the devices useless, according to researchers who demonstrated the attack Tuesday.The exploit uses a standard Wi-Fi network that generates a specially designed secure sockets layer (SSL) certificate to exploit the bug, according to the researchers, who work for Israel-based Skycure. The encrypted communication causes whatever apps happen to be connected to the booby-trapped Wi-Fi network to crash. The vulnerability was introduced in version 8 of the Apple mobile operating system.
