Australians Warned to Prepare for Unexpected Online Service Outages as Cyber Threats Grow

According to a report from the Australian Signals Directorate (ASD), Australians should prepare for essential online services to go offline unexpectedly as cybersecurity threats increase. Released following a period where the agency responded to 1,500 cybersecurity incidents in the 2025-26 year, the report emphasizes that system security must be prioritized over availability.

Rising Threats and AI Integration

The ASD reported an 80% increase in potential malicious cyber incidents notified to external entities, totaling over 4,400 over the past year. Officials noted that hostile foreign governments, criminals, and hackers are increasingly utilizing artificial intelligence to gather intelligence, disrupt infrastructure, and execute attacks more efficiently.

• Automated Defenses: ASD Director General Abigail Bradshaw stated that advanced AI tools are necessary to automate defenses and stay ahead of AI-enabled attackers.
• State-Based Activity: Networks in Australia faced persistent breach attempts from state-based actors, which the agency indicated could be linked to preparations for future intelligence collection or disruption activities.

Modernizing Technology and Recommendations

The agency highlighted legacy technology and unsupported systems as primary targets for malicious actors. To counter these rising risks, the government urges organizations to modernize their technical foundations and adopt advanced AI models for security.

• Prioritizing Security: Organizations are advised to favor security over continuous uptime, which may result in temporary, unexpected service outages.
• Reporting Incidents: Entities are encouraged to update their systems regularly, report suspicious activities, and seek assistance from the ASD.
