Changing Time and Date to Jan 1, 1970 will permanently brick 64-bit iOS devices

- sbierwagen 11y agoAttackers 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. Not 100% sure this is true. Full NTP clients (as opposed to SNTP) should poll several servers, and throw away answers that differ too much from the others. And does the iPhone even get time by NTP? Can't it get time from the cell network?
- jlgaddis 11y agoI haven't monitored the traffic from my iPhone to test, but most cell phones get their time from the cell towers as they have to be in sync.
- mikestew 11y agoThough "permanently brick" is incorrect. It would appear that physically disconnecting the battery will work, or just let the thing boot-loop itself until the battery dies and then recharge.
