Does your aunt know how to apply bios updates? And that's assuming such updates are available at all. I searched up various Z170 (released mid 2015) chipset motherboards, and the bios updates seem to end around early-mid 2018. That works out to around 3 years of patches. It's therefore reasonable to assume that if any exploit was discovered today, any systems 3+ year old are sitting ducks.
