After Apple fixed the issue in iOS 9.3.1, two security researchers have now uploaded a video on YouTube showing how to exploit this bug from a remote location, with no access to the user's phone. The setup involves attackers putting up a Wi-Fi network on which they're running a rogue NTP server. This server tells iOS devices syncing their time that it's December 31, 1969, 23:59:00. Twenty minutes later, if the battery didn't catch fire (which is possible with this new exploit), the iPad or iPhone device is permanently and irreversibly bricked.
