A ransomware variation called WanaCrypt0r 2.0, otherwise called WanaCry or WCry, has bolted up more than 75,000 PCs in 99 nations over the most recent 24 hours as per cyber security company Avast. The National Health Service in the UK, Spanish media communications organisation Telefónica, and FedEx in the US are among the countless casualties. Here are the means by which you can secure yourself.
Wanacry was first identified in February and Microsoft released a patch in March. If you have not updated your Windows software recently, do it now. The current versions of Windows 10 and the build schedules for each version can be found here. You can find the Windows version and build that is running on your system by going to Settings>System>About.
If you need to update to protect against WanaCry, Microsoft has gathered patches for all currently supported versions of Windows which can be found here. They have also taken the highly unusual step of patching legacy versions of Windows that have been unsupported for as long as three years. If you are running one of these versions of Windows you might want to give serious consideration to upgrading to the current version. In the meantime, you can thank Microsoft for reaching out to help you and download the patch.
If you have up-to-date malware protection software from a reputable cyber security company such as Avast installed on your computer, you are probably protected. Check your cybersecurity company’s website to make sure you are. WanaCry is a worldwide, runaway threat. If your cybersecurity company’s website has nothing to say about it, don’t assume you are protected. Make sure you are running the current version of Windows.
