A number of large Australian organisations using the popular Microsoft Exchange have been warned they are exposed to cyber attacks because they have not patched their systems.
The Australian Cyber Security Centre has issued updated advice following vulnerable Microsoft Exchange systems being compromised by malicious cyber actors.
Assistant Minister for Defence Andrew Hastie said immediate steps were needed.
"The ACSC has identified a large number of Australian organisations yet to patch affected versions of Microsoft Exchange, leaving them exposed to cyber compromise," Mr Hastie said on Wednesday.
"This can be done by implementing the necessary network security patches as soon as possible and then following the detection steps outlined by Microsoft."
He said if organisations were unable to quickly deploy the patches, they should consider preventing internet access to the exchange web server.
