Such large scale attacks are organized and effectively weapons.

Now, think which country wants to attack Australia and teach it lesson for various noises it has been making against it.

Now look at the past history of the said country.

There is your evidence.

So that means the next cyber-attack against the US comes from Afghanistan, Iran or Vietnam?

That's NOT evidence...could be true or not.

PS: But i think your 'evidence' is exactly what people of color have a problem with, especially in the US.
