The Australian Cyber Security Centre (ACSC) has become aware that Advanced Persistent Threat (APT) actors have been scanning for and attempting exploitation against unpatched versions of Telerik UI for ASP.NET AJAX using publicly available exploits. Successful exploitation could allow an attacker to upload files to the vulnerable server to facilitate further compromise.
Implementing Multi-Factor Authentication
Multi-factor authentication is one of the most effective controls an organisation can implement to prevent an adversary from gaining access to a device or network and accessing sensitive information. When implemented correctly, multi-factor authentication can make it significantly more difficult for an adversary to steal legitimate credentials to facilitate further malicious activities on a network. Due to its effectiveness, multi-factor authentication is one of the Essential Eight from the Strategies to Mitigate Cyber Security Incidents.
How to Combat Fake Emails
Organisations can reduce the likelihood of their domains being used to support fake emails by implementing Sender Policy Framework (SPF) and Domain-based Message Authentication, Reporting and Conformance (DMARC) records in their Domain Name System (DNS) configuration. Using DMARC with DomainKeys Identified Mail (DKIM) to sign emails provides further safety against fake emails. Likewise, organisations can better protect their users against fake emails by ensuring their email systems use and apply SPF, DKIM and DMARC policies on inbound email.
