“The ACSC has identified a large number of Australian organizations that have yet to patch affected versions of Microsoft Exchange, leaving them exposed to cyber compromise,” Hastie said Wednesday.
“This can be done by implementing the necessary network security fixes as soon as possible and then following the detection steps outlined by Microsoft. “
He said if organizations were unable to quickly deploy the fixes, they should consider preventing Internet access to the Exchange web server.
