If ninety days has passed and the developer has yet to come up with a solution, only then will the researchers inform the public so they can at least take preventive action. If you are using unsupported versions of Windows, including Windows XP, Vista, Server 2003 or 2008, apply the emergency patch released by Microsoft.
The initial attack on Friday - called "WannaCry" - first infected computers that run the UK's hospital network, Germany's national railway and several other companies and government agencies worldwide in what is being called the "the biggest ransomware attack ever". The affected groups include the United Kingdom hospitals, FedEx, a Spanish telecom, the Russian Interior Ministry and much more. It is believed that 200,000 computers were affected by the ransomware. So, they analyze weaknesses in your operating system's code and keep a figurative vault of ways to hack into computers, like how the CDC stores real viruses.
The culprit was "ransomware" known as WanaCryptOr 2.0, or WannaCry.
The exploitation of EternalBlue, suspected to have been developed using a hacking method leaked from US National Security Agency, allows the malware to spread through file-sharing protocols set up across the internal networks of organisations, many of which criss-cross the globe, according to Financial Times.
Companies often release software updates to fix vulnerabilities that can be exploited to install ransomware. The higher risk of being encrypted lies at those Microsoft computers that are not patched with the update.
How To Protect Yourself From WannaCry Ransomware?
This ransomware simply locks up the files on an infected computer and encrypts them so that the owner or authorized user can no longer access them.
Since increasing numbers of systems running older versions of Windows were affected, Microsoft had made a decision to push an emergency patch for Windows XP and Windows Server 2003, urging users to deploy the patch as soon as possible to limit the impact of WannaCry.
The "WannaCry" malware exploits a hole in outdated Windows operating systems. Take note that it is created to target devices running Windows OS and the files contained therein, therefore it's not a threat to Android and iOS mobiles.
If you're still using Windows XP make sure you get all the latest updates, though Microsoft officially stopped supporting XP a couple years ago, this patch is available through the update tool in Windows.
