Understanding the 2023–24 Annual Cyber Threat Report: Key Takeaways for Businesses

Cybersecurity threats are evolving, and businesses must stay vigilant. The 2023–24 Annual Cyber Threat Report highlights Australia’s increasing cyber risks, driven by global conflicts, rising tensions in the Indo-Pacific, and technological advancements that cybercriminals exploit. These threats target governments, businesses, and households, making cybersecurity a top priority for every organisation.

The Role of the Australian Signals Directorate (ASD)

The Australian Signals Directorate (ASD) is responsible for protecting Australia from cyber threats. The ASD monitors electronic communications, defends critical infrastructure, and supports national security efforts. Over the past year, ASD received more than 36,700 calls for assistance and handled 1,100 cyber incidents. Foreign-backed hackers, particularly from China and Russia, have been using sophisticated tactics to breach networks and steal sensitive data. Critical infrastructure sectors such as energy and healthcare remain primary targets due to the potential for widespread disruption.

Cybercrime: A Growing Concern for Businesses

Cybercrime is on the rise, with criminals leveraging advanced tools like artificial intelligence to carry out attacks more effectively. In FY2023–24, the most commonly reported cybercrimes in Australia included:

  • Business Email Compromise (BEC) – Cybercriminals manipulate email systems to defraud businesses.
  • Fraud – Online scams targeting financial assets.
  • Ransomware – Attackers encrypt data and demand payment for its release.
  • Data Theft Extortion – Criminals steal and threaten to expose sensitive business information.

These attacks cause significant financial losses, operational disruptions, and reputational damage to businesses.

Ransomware: A Major Threat to Small Businesses

Ransomware remains one of the most severe cyber threats, particularly for small and medium-sized businesses (SMBs) that often lack the resources for strong cybersecurity measures. Attackers encrypt files, demand ransom payments, and in many cases, steal sensitive data to use as leverage.

What Can Businesses Do?

  • Do not pay ransoms – Paying does not guarantee data recovery or prevent further attacks.
  • Implement strong security measures – Regular system updates, secure backups, and proactive threat detection are crucial.
  • Adopt secure-by-design products – Using products with built-in security reduces vulnerabilities.

Cybersecurity Requires Continuous Effort

Protecting a business from cyber threats isn’t a one-time task—it requires ongoing attention and investment. Businesses should follow the Essential Eight, a set of cybersecurity best practices that include:

  1. Regular software updates.
  2. Multi-factor authentication (MFA).
  3. Network segmentation.
  4. Least privilege access controls.
  5. Secure data backups.
  6. Application whitelisting.
  7. User training and awareness.
  8. Incident response planning.

Critical infrastructure businesses must assume cyberattacks are inevitable and develop tested response plans to recover quickly from incidents.

How to Report Cybersecurity Incidents

Businesses experiencing a cyberattack or security breach must report it immediately. Cybercrime reports are referred to relevant law enforcement agencies, while cybersecurity incidents should be reported through the ReportCyber portal.

Common Cybersecurity Incidents to Report:

  • Denial of Service (DoS) attacks.
  • Unauthorised network access.
  • Data breaches or leaks.
  • Malware or ransomware infections.
  • Phishing attempts.
  • Other suspicious cyber activity.

When reporting, businesses should provide indicators of compromise, network traffic logs, and relevant analysis to assist investigations.

How the ASD Can Help

The ASD offers 24/7 technical assistance to businesses affected by cyber incidents. They provide incident response advice, help contain and remediate threats, and can deploy forensic specialists for complex cases. Businesses and individuals should report suspicious cyber activities to cyber.gov.au/report or contact the Australian Cyber Security Hotline at 1300 CYBER1 (1300 292 371).

Key Takeaways for Businesses:

  • Cyber threats are growing, with ransomware and data theft being major risks.
  • Small businesses are particularly vulnerable but can mitigate risks with strong security practices.
  • Cybersecurity requires continuous effort, proactive measures, and adherence to best practices like the Essential Eight.
  • Reporting incidents promptly helps businesses and government agencies respond effectively.
