I'm afraid this is the next step in a cyber war, to hack not just the traditional computer systems and smartphones, but also to get into the industrial systems, into infrastructure, including critical infrastructure
I wonder why cybercrooks didn't target industrial systems massively yet. Maybe because the "traditional market" is still lucrative enough?
Cybersecurity in industrial systems is most of the time a joke. I know an example of an industrial device provider asking for an open connection 24h a day to its system without even being able to provide a fixed public IP to filter (a little bit) the input. The same provider did not realize why it was wrong, and moreover didn't care.
There's a bright future for cybercrooks, they have plenty of devices to play with.
