Here's the thing, though: It doesn't take a genius to know US power infrastructure is vulnerable. We've been saying it ourselves for years. This attack was not complex to execute with fairly minimal, publicly available knowledge. Why probe? I guess to see how long it takes us to fix, but that just... doesn't seem worth it to me. If I were China, say, would I really be willing to attack the domestic United States just to see what the US would do? Don't I have the resources to know what the US would do without trying it?
