Update on WanaCry global ransomware incident

Priority Level: 
15 May 2017

The Australian Government is aware of a large-scale ransomware campaign that has impacted organisations globally.

We recommend Australian businesses, households and individuals take steps now to protect their computers, networks and devices.

The Australian Cyber Security Centre (ACSC) has been engaging with Australian businesses and industry sectors over the weekend to ensure they are aware of the threat and have taken appropriate measures.

A small number of businesses have reported likely infection and there will likely be more cases in days to come.

The situation continues to be monitored closely and advice for individuals and organisations will be updated on the ACSC website as required.

Recommended action

  • Immediately install the latest updates for applications and operating systems, especially Microsoft Windows.
  • Confirm that backups are available and working.
  • If you have been affected by the WanaCry ransomware, report the incident to the Australian Cybercrime Online Reporting Network (ACORN).

What is ransomware?

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.
