In light of the global ransomware attack, known as WannaCry – (BBC ARTICLE) we would like to share our IT knowledge and advise local businesses of what steps need to be taken to safeguard your business from ransomware attacks.
Ransomware attacks are typically delivered through the email system. They occur due to a combination of vulnerabilities in software and users inadvertently opening a malicious email.
WannaCry is a typical ransomware style attack that encrypts information until a fee of between £200 and £500 is paid to release the information.
It’s not happened yet… What now?
- Microsoft released an update on 14th March 2017 to mitigate a vulnerability in the operating system to prevent the ransomware spreading. This should be installed on all machines to provide maximum protection – LINK HERE
- The update is applicable for Windows Vista / Windows Server 2008 and later. There is no update for older operating systems, as Microsoft no longer release security updates for operating systems that are beyond extended support. We urge you to upgrade your operating system to a version that is under support.
- To further mitigate any potential loss of information, backup routines should be assessed to see if more regular backups can be taken. This will improve your ability to recover information and reduce the overall risk.
- Check all machines have antivirus (servers and desktops) and ensure that it is up-to-date.
- Check you have an email filtering technology in place and that it is up-to-date.
- Inform your staff to be extra vigilant when opening emails, specifically when following links or opening attachments.
