NYT story on cyber attacks on two major SouKo banks - presumably by NorKo.
I think this becomes the new brinksmanship/signaling in the digital age, meaning it's truly a virtual form of warfare and not a real warfare domain per se. It's easier and more clear than the usual diplo protests.
So we have this as a fifth vein of cyber (offensive/offending).
The five categories, in my mind, are:
What I don't see is cyber as a separate offensive warfare category - i.e., that and that alone as THE attack. You use as enabler in traditional attack, or its virtual warfare at best (remember that virtual means "not X").
That's why I don't find cyberwarfare so novel or weird or supremely trumping as some do. It's just a lot of old modalities updated and augmented - nothing more.
