What is at risk? Are companies preparing more given circumstances? Such attacks could range the gamut from core banking and financial operations to power grids.
I described our current gentle, peaceful, mode of life as
"cybersecurity as it is now is... intense, it's a war zone, where your fortifications are made out of crates of nitroglycerine
any computer can be hacked, that then becomes a gateway to all the other computers
it really frosts my cookie that this was SOLVED back in the 1970s, but everyone forgot the solution"
Think I'm being hyperbolic with that estimate? Consider the supply chain chaos when everyone was working together, trying to get you toilet paper. That could ramp up x100 for everything, money, fuel, food, medicine, power, pipelines, etc.
If people actually start taking things out, a lot of people are going to have to figure out how to re-image their systems and restore from last month's backup, then delta forward.
Depending on the nature and impact of an attack, I believe it could provoke proportional kinetic response.
