I understand it's affected only XP systems.
But I do not know how large institutional XP got infected. The virus is supposed to only load if a link is clicked.
How did so many systems get fooled?
Not just WIN XP, but Vista and Windows 8. So long as you did routine WIN 7 and WIN 8.1 updates, you should have been fine.
So many hospitals get crypto ransomware as they fail to upgrade from unsupported OS such as WIN XP. Running an updated AV is no insurance, security patches adding additional layers of protection. In large enterprise environments, it only takes one employee to be fooled into clicking an infected link, and encrypting not only their local drives, but network attached drives. All because some CEO decides it unnecessary to allocate funds to protect their network.
