Following my previous post which can be found here, I talked this morning to Mark Murphy on BBC Radio Suffolk about WannaCry and the effect it has had on the NHS, what needs to be done to stop it happening again and what we can do to protect ourselves.

PLEASE ensure your computers have all their updates installed and make sure you have Anti-Virus software installed.
WannaCry Ransomware has now affected over 200,000 systems in 150 countries around the world. In the UK, the National Health Service has been very badly affected causing massive disruption across the country.
Although the initial outbreak was stopped, several new versions of this virus have been reported in the ‘wild’. Some have been stopped by registering the ‘kill-switch’ domain name, but it is widely believed that a version or versions of the virus has been released that does not contain a kill-switch.
ONLY COMPUTERS RUNNING WINDOWS ARE IN DANGER OF INFECTION CURRENTLY.
Before you do ANYTHING else BACKUP your important files onto removable storage. Upon completion of this backup, ensure it is kept separately from your computer in a safe place. Should you become infected with this Ransomware, you don’t need to consider paying any kind of ransom as your files are safely stored elsewhere.
UPDATE your antivirus software, if you don’t have antivirus software installed enabled Windows Defender which is free.
You MUST ensure that your Windows system is correctly patched with the latest security updates.
If you use Windows, install the patch that Microsoft has released to block the specific exploit that the WannaCry ransomware is using. You can find instructions on this page in the Microsoft Knowledge Base. You can also directly download the patches for your OS from the Microsoft Update Catalog.
If you are using an unsupported version of Windows like Windows XP, Windows 2008 or Server 2003, you can get the patches for your unsupported OS from the Update Catalog. We do recommend that you update to a supported version of Windows as soon as possible.
Update your Antivirus software definitions. Most AV vendors have now added detection capability to block WannaCry.
