Why is that? Was it just restraint? North Korea didn't show a lot of that to Binance but perhaps they are leaving traditional infrastructure alone because it's harder to profit from.
Actually it seems somewhat remarkable crypto exchanges aren't hacked more often. I guess that's another message from this - somehow people can build secure infra from these apparently broken pieces. Perhaps there's hope.
Why haven’t these been operationalized? NK resorted to social engineering in their latest bitcoin heist despite there been a thousand holes in the system.
To me, this points towards these holes are near impossible for humans and traditional tooling to find and Pandora’s box has been opened, or that these holes are not open to abuse in practice.
I guess the answer is that in most applications you are able to keep most users off the box altogether.
