Let's do the Timewarp Again

Presented at Kiwicon X: The Truth is In Here (2016), Nov. 18, 2016, 1:45 p.m. (30 minutes)

GPS is used for life critical services like finding a date on Tinder, hailing an Uber to drive to the date and checking the time to ensure you are not late to the date. What happens when GPS breaks? Well for less than US$500, GPS can be spoofed, so you can be anywhere on the planet, at any time in history. This talk will look at spoofing GPS and what happens when the time no longer travels forward, at the rate of 9,192,631,770 vibrations of the ¹³³Cs atom. We can make NTP go backwards. We can make the GPS on your iPhone think it is 1970 all over again. What happens to your systems in 2038 or on 31 December 9999? What happens to time based two factor authentication when the assumption of time only goes forward is broken? "Oh noes, how can we stop all these fun GPS shenanigans?" Well that is where gpsnitch steps in.
