It’s being reported that some vehicle manufacturers are failing to wipe replaced components from their cars, meaning people’s personal data can be found on second-hand kit.

TechHQ reports that so-called “white hacker” (someone who hacks things to show problems and not for nefarious purposes) GreenTheOnly has found people who have their car retrofitted with new hardware could therefore be the victim of a data breach.

It says most of the data that could be accessed was to do with infotainment systems, including “owner’s home and work location, all saved wi-fi passwords, calendar entries from the phone, call lists and address books from paired phones, Netflix and other stored session cookies.” Session cookies meant hackers could take control of accounts.

It says all vehicle manufacturers should make sure deleting all devices is the norm.
