Security researcher had to jailbreak their car just to update the clock

A security researcher has revealed how they were forced to update the time on their car infotainment system using reverse engineering techniques. Of course, invasive tech surgery shouldn’t be needed for this kind of basic routine daylight saving time tweaking task. However, Rasmus Moorats’ 2014 Renault Latitude wouldn’t allow him to adjust the time because the original navigation map SD card was missing.

Moorats had been warned.

They seem to have believed it was a skill issue of the prior owner and, because the maps it contained were chronically out of date, they decided to confidently decide they didn’t need the SD card...

The time to adjust non-connected clocks to daylight saving time inevitably came, and Moorats decided to adjust the in-car time display, which …
