Re: Let me get this straight
The concentrated resources of even a poor country can buy a lot - eg private jets for the dear leader, or several thousand hackers with decent kit.
Agreed. This attack did not require developed-world infrastructure, robust international trade, or a happy populace to carry out.
I'm agnostic on the question of the attackers' identity and sponsorship. I don't find it unlikely that it was North Korea; I don't find it unlikely that it was someone else. And I'm not sure it matters very much.
