The broad-based ransomware attack has appeared in at least eight Asian nations, a dozen countries in Europe, Turkey and the United Arab Emirates and Argentina and appears to be sweeping the world, the researchers said.
WHAT IS SO SPECIAL ABOUT WANNACRY?
WannaCry is not just a ransomware program, but also a worm.
This means that he gets into his computer and looks for other computers to try to spread as far as possible.
Ransomware is in the habit of changing and therefore changes over time to find different ways of accessing computers or repairing patches (OS updates that often include security updates). Many security companies are already aware of WannaCry in past ways and most are looking at this time to see how it could be stopped.
Several security firms reported that WannaCry exploits a vulnerability in Microsoft and that Microsoft corrected this in March. People do not always install updates and patches on their computers, so this means that vulnerabilities can stay open much longer and make things easier for hackers to get in.
It took advantage of a vulnerability in the Windows operating system that is believed to have been developed by the National Security Agency, which was made public last month. It was among a large number of hacking tools and other files that a group known as the Shadow Brokers released on the Internet. Shadow Brokers said they got it from a secret NSA server.
The identity of Shadow Brokers is unknown, although many security experts believe that the group that emerged in 2016 is linked to the Russian government.
The NSA and Microsoft did not immediately respond to requests for comments.
