Bruce Schnier is talking about it:
Over the past year or two, someone has been probing the defenses of the companies that run critical pieces of the Internet. These probes take the form of precisely calibrated attacks designed to determine exactly how well these companies can defend themselves, and what would be required to take them down. We don’t know who is doing this, but it feels like a large a large nation state. China or Russia would be my first guesses.
The problem is that the internet has made everything so convenient that everyone depends on it to automate everything. If suddenly we had to go back to phone call orders, and phoning Fed-Ex to arrange shipping, none of those companies have the personnel to handle all those calls. Everything would grind to a halt. What is unclear is if that would begin to approximate the 90% casualty rate of an EMP attack that took down the power grid.
If there is a major global conflict, expect this to happen and be prepared.
Self-sufficiency is the new black.
