A ransomware cyber-attack that may have originated from the theft of “cyber
weapons” linked to the US government has hobbled hospitals in England and
spread to countries across the world.
"Ransomware is a type of malware that encrypts a user’s data, then demands
payment in exchange for unlocking the data. This attack was caused by a bug
called “WanaCrypt0r 2.0” or WannaCry, that exploits a vulnerability in Windows.
Microsoft released a patch (a software update that fixes the problem) for the
flaw in March, but computers that have not installed the security update remain
vulnerable."
