The Australian Cyber Security Centre (ACSC) has noticed that there has been a historical pattern of cyber-attacks against Ukraine that have had international consequences. Malicious cyber activity could impact Australian organisations through unintended disruption or uncontained malicious cyber activities.
While the ACSC is not aware of any current or specific threats to Australian organisations, adopting an enhanced cybersecurity posture and increased monitoring for threats will help to reduce the impacts to Australian organisations.
The ACSC strongly recommends organisations implement the Essential Eight mitigation strategies from the ACSC’s Strategies to Mitigate Cyber Security Incidents as a baseline. This baseline, known as the Essential Eight, makes it much harder for adversaries to compromise systems. The Essential Eight mitigation strategies are:
- Application control;
- Patch applications;
- Configure Microsoft Office macro settings;
- User application hardening;
- Restrict administrative privileges;
- Patch operating systems;
- Multi-factor authentication; and
- Regular backups.
The ACSC is monitoring the situation and is able to provide assistance or advice as required. Organisations that have been impacted or require assistance can contact the ACSC via 1300 CYBER1 (1300 292 371).
