What the attack does
Cyber bad guys have spread ransomware, known as WannaCry, to computers around the world. It locks down all the files on an infected computer. The hackers then demand $300 in order to release control of the files. That's why it's called ransomware.
How it happened
WannaCry takes advantage of a vulnerability in Microsoft Windows.
The software tools to create the attack were revealed in April among a trove of NSA spy tools that were either leaked or stolen. The tools were made public by a hacking group called the Shadow Brokers.
Microsoft released a security patch for the vulnerabilities in March. But many corporations don't automatically update their systems, because Windows updates can screw up their legacy software programs.
