Protecting against ransomware
- The ransomware takes over users’ files.
- Once in control, the ransomware demands users pay to ‘unlock’ their machine.
- Computers in more than 150 countries have been infected.
May and June 2017 saw the two global ransomware attacks in 6 weeks. They both used known weaknesses in Microsoft’s Windows operating system to spread far and fast and has has prompted everyone to review their security policies immediately.
The ransomware uses a vulnerability in a Windows Server component to spread within corporate networks. For May’s WannaCry ransomware, Microsoft took the highly unusual step of releasing free security updates for those out-of-support versions of Windows, which can be downloaded from its website.
For WannaCry, the most vulnerable operating systems include Windows Server 2003 and Windows XP, both of which have not been sold for over a decade; and Windows 8, which some users prefer to the supported Windows 8.1 because of differences between the two versions of the operating system
