I know something. Every fucking server with public facing infrastructure is not getting hacked left and right at the moment.

So you make of that what you will, but in my experience it means the exploitation comes hand in hand with some far more esoteric chain that is not easy to put in practice.

What was the timeline for the release of WannaCry following the exposure of ETERNALBLUE and DOUBLEPULSAR...?

I accept that one would expect substantially shorter timelines in the age of AI, but given that WannaCry is suspected of being state-funded and even then: 1) it took a month to appear and 2) ETERNALBLUE and DOUBLEPULSAR were essentially already finished, weaponized malware off the shelf.

All of this to say that just because you don't see mass exploitation right this second doesn't mean there isn't a wormable exploit that needs patching. WannaCry didn't exist until it did, and suddenly everyone who failed to patch beforehand looked foolish.
