High latency still makes those machines less efficient to both compromise and them use to scan a bunch of ip addresses. ie US hackers hacking Chinese machines to then hack US machines is really inefficient.

Latency doesn’t prevent such things from working, but your better off hacking local resources and then using those resources to scan locally. So all things being equal either there’s a huge surplus of especially vulnerable Chinese machines or a surplus of Asian hackers.

To be clear there could just be a huge surplus of easily hacked Chinese machines, but that itself would be noteworthy.
