Australians need to apply latest updates to protect from WanaCry ransomware: Alert Priority High

Stay Smart Online is urging Australian businesses and individuals to apply the latest updates for their applications and operating systems, especially Microsoft Windows, as people continue to fall victim to ransomware campaigns, including potentially WanaCry.

Stay Smart Online first warned about WanaCry on 13 May  and provided advice on how to protect yourself and your business on 15 May.  However, media is reporting today that Australian businesses continue to be impacted by the ransomware.

What to do now

There are very simple steps you can take to reduce the risk of your personal and business records being impacted by WanaCry ransomware.  The top two steps are:

  • Immediately install the latest Windows updates for applications, software and operating systems.  Note that updates are also available for Windows XP.
  • Confirm that backups are available and working – guidance on backups is available for businesses and individuals and households.


WanaCry – like all ransomware –is a type of malicious software (malware) that makes your computer or its files unusable unless you pay a fee (a ransom).

Ransomware is one of the most frequent and damaging types of malware affecting people today. It can affect both individuals and organisations alike, and can impose significant costs – in both recovery and down time.
