One of the large concerns about hacks is the eventual assault on public infrastructure. It finally happened, in the Ukraine. About 80,000 people were left without power because of an attack that opened circuit breakers thereby cutting the power. After the power was out, the hackers continued the attack, delaying the recovery efforts. Military and government installations tend to be better protected, so one of the concerns has been that public systems will be more vulnerable, harder to defend, and could result in greater public outcry. Now that the attack has succeeded once, it reinforces the need to defend similar systems, possibly something that is beyond strained budgets.
