EU to Declare Cyber-Attacks “Act of War”. USA likely to follow

"European Union member states have drafted a diplomatic document which states serious cyber-attacks by a foreign nation could be construed as an act of war.

The document, said to have been developed as a deterrent to provocations by the likes of Russia and North Korea, will state that member states may respond to online attacks with conventional weapons “in the gravest circumstances."

The framework on a joint EU diplomatic response to malicious cyber activities would seem to raise the stakes significantly on state-sponsored attacks, especially those focused on critical infrastructure.
