ransomware update

Kinda crazy how quickly this ransomware problem propagated and then quickly died. It was amazing seeing how quickly it decimated a number of big systems and spread throughout the world. Also crazy that all it took was someone registering and establishing a domain to resolve it. What was more astonishing was seeing how many these large institutes admitted to running on XP still and not updating at all for so long! I wonder if this will make companies, hospitals and schools suddenly upgrade versus being happy they dodged that bullet.
