Do you WannaCry? Ransomware cyberattacks: what you need to know.
Posted on: May 19th, 2017
By now you have probably heard about the recent ransomware cyberattack called WannaCry. The attacks started on Friday 12 May 2017 and to date, have infected more than 230,000 computers in over 150 countries.
Major companies in England and Spain were infected including the British National Health Service and FedEx in Spain.
Once it hits just one computer, it can very quickly spread over an entire network. When WannaCry hit, it didn’t waste it’s time hitting devices on the local network and remote host. The network devices infected were the ones that didn’t have the latest security update.
Microsoft issued a security patch update for Windows on 14 March 2017, almost a full two months before the attack, however the systems that were infected didn’t have the update installed. Most of the systems affected were running the older operating systems of Windows XP and Windows Server 2003.
IT systems and infrastructure are more far reaching that just the humble server or PC. When WannaCry hit the National Health Services it infected up to 70,000 devices including computers, blood-storage fridges, operating theatre equipment and MRI scanners. This could have resulted in loss of lives and we don’t yet know the full economic impact.
For us in Australia, mostly we have been unharmed. However, next time we might not be as lucky. Here is what you can do to be prepared:
