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.
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?
