The danger of these kinds of threats is not limited to exposure of personal information, though. For example, take a look at Norsk Hydro. A ransomware situation took down the control systems of an aluminum plant. The company mostly got lucky - they still had senior engineers around who could control the system by pen and paper. Otherwise, you'd have a lot of half-processed slag solidify inside the line. At that point, there's little to do besides ripping all of it out and rebuilding the line in a newfound empty factory building. And at that point, there are two scary areas to research: Industrial control networks which are abused in a wide area scenario. And the industrial ability to recover from these kinds of outages, if rebuilding a factory takes years. And I guess the security practices and budgets in that sector.
