We need to have military responses to these attacks. Ransomware is running rampant because they don't fear any punishment for attacks. If people attacked our hospitals and pipelines with explosives we wouldn't sit by and do nothing.
You are proposing that we attack them with explosives, are you fine with them retaliating in kind?
What if you lived next to some hackers targeting a foreign country, would you think it's acceptable to get blown up for their actions?
At least not with the 100% confidence that politicians would want before the US military starts dropping JDAMs on buildings.
I would give fairly even odds that something like this is the work of an organization nation state, and also even odds that it's the work of some underemployed teenagers in a basement.
