Biden notes that a physical war could result from cyber breaches. In spite of NATO, Putin and crew could do some damages that would cost billions.
NotPetya was the largest and most expensive cyberattack ever and was perpetrated largely on Ukraine by Russian criminals working for the government. It caused more than $10 billion in damages in 2017. Is part 2 in order?
I’m hoping that now we will be ready and that NATO will act together. This is all new territory though. We haven’t seen physical war yet, but I think it will be tit-for-tat unless it takes down some infrastructure that is critical and/or relies on IRL human processes.
