Patrick Kelley and Matt Harrigan managed to automate the exploitation of the date bug that bricked many iPhones back in February, armed with only $120 of electronics, a basic understanding of networking, and a familiarity with the way Apple devices connect to wireless networks.
Using a custom Raspberry Pi setup built by Kelley, a wifi access point resembling a commonly trusted network spoofs Apple’s NTP servers to pass the 1/1/1970 date to the device. This starts a chain reaction of software instability resulting in a observed temperatures up to 54°C… which is hot enough to brick a device.
This issue has been fixed with the release of iOS 9.3.1. You can find download links for the new firmware here.
