This is interesting. Seems like a really weird bug.

This is interesting. Seems like a really weird bug.
When the date of a 64-bit iOS device is set to January 1, 1970, the device will fail to boot.
Connecting the device to iTunes and restoring the device to factory defaults will not put the device back in working order. Instead, a physical repair is required.
When connected to public Wi-Fi, iPhone calibrates its time settings with an NTP server. Attackers can set send malicious NTP requests to adjust every iPhone's time settings to January 1, 1970, hence brick every iPhone connected to the same network.
