Strengthening Cybersecurity in Education: Lessons from the 2023–2024 ASD Cyber Threat Report

Educational institutions are increasingly becoming targets for cybercriminals due to their vast repositories of sensitive data and often constrained resources. The Australian Signals Directorate’s (ASD) 2023–2024 Cyber Threat Report highlights the growing frequency and sophistication of cyberattacks targeting schools, universities, and research institutions. The findings underscore the urgent need for the education sector to strengthen its cybersecurity posture. Below, we outline the challenges faced by the sector and actionable strategies to mitigate risks.

The State of Cybersecurity in Education

1. A Cybercrime Every Six Minutes

Cybercrime has become pervasive, with Australia reporting an incident every six minutes. Educational institutions are particularly vulnerable due to their decentralized networks, rapid adoption of digital tools, and reactive approaches to cybersecurity.The shift to remote learning during the pandemic further expanded the attack surface. Platforms such as Zoom and Microsoft Teams became essential but introduced new vulnerabilities, from unpatched software to unsecured devices. Phishing campaigns targeting these weaknesses have proven highly effective, with attackers leveraging fake student loan portals and online learning systems to steal credentials.

2. Ransomware Attacks

Ransomware continues to be a significant threat, with educational institutions frequently targeted due to their reliance on uninterrupted access to critical systems. The ASD report highlights severe financial consequences, with smaller institutions losing up to $46,000 per incident and medium-sized organizations incurring nearly double that amount. Beyond financial costs, ransomware undermines trust among students, parents, and staff. Attackers often employ double-extortion tactics, encrypting data and threatening to leak sensitive information if ransoms are not paid. For institutions, the implications are both operational and reputational.

3. Data Breaches

Student databases containing personally identifiable information (PII) such as names, addresses, financial details, and medical records are highly valuable to cybercriminals. These breaches can lead to identity theft, phishing scams, and significant reputational damage.

Often, institutions are unaware of breaches until stolen data appears on the dark web. For example, in one incident, hackers leaked scholarship applicant information, exposing students to targeted attacks. Such breaches extend beyond immediate victims, impacting the wider community that relies on these institutions for safety and privacy.

4. State-Sponsored Espionage

Universities and research institutions are increasingly targeted by state-sponsored actors, particularly those conducting research in biotechnology, artificial intelligence, and defence. These attacks aim to steal intellectual property and gain strategic advantages. Advanced Persistent Threat (APT) groups backed by nation-states use sophisticated methods to infiltrate networks and maintain long-term access. The implications are significant, from compromised research integrity to national security concerns.

Why the Education Sector is a Target

• Sensitive Data Troves: Schools and universities store vast amounts of valuable information, from student records to research data.
• Decentralized Systems: Outdated IT infrastructure combined with modern SaaS tools creates a fragmented and vulnerable environment.
• Budget Constraints: Cybersecurity often takes a backseat to other pressing financial priorities.
• Increased Digital Dependency: Remote learning and Bring Your Own Device (BYOD) policies have expanded the attack surface dramatically.

ASD Recommendations: A Strategic Framework

1. The Essential Eight: A Roadmap to Resilience

The ASD’s Essential Eight mitigation strategies provide a practical and cost-effective framework for institutions to defend against cyber threats. Key strategies include:

• Application Whitelisting: Prevent unauthorized applications from running to block malicious software.
• Patch Management: Regularly update systems to close vulnerabilities.
• Restrict Admin Privileges: Limit user access to only what is necessary, minimizing the impact of breaches.

These measures are particularly effective for the education sector, where resources are limited but the risk of ransomware and data breaches is high.

2. Incident Response Readiness

The ACSC handled over 1,100 cyber incidents last year, underscoring the importance of having actionable and tested incident response plans. Key elements include:

• Tabletop Exercises: Conduct regular simulations to train staff on how to respond to ransomware attacks, phishing attempts, and data breaches.
• Clear Communication Protocols: Establish procedures for reporting and escalating incidents quickly to limit damage.
• Regular Updates: Ensure response plans evolve alongside emerging threats and that all staff are trained on the latest protocols.

3. Threat Intelligence Sharing: Power Through Collaboration

The Cyber Threat Intelligence Sharing (CTIS) service is a vital resource for the education sector. It enables real-time sharing of threat intelligence, fostering collaboration and proactive defence.

• Key Benefits:
  • Early Detection: Receive real-time alerts on phishing domains, malware signatures, and other emerging threats.
  • Community Defence: Alerts shared by one institution can protect others from similar attacks.
  • Resource Sharing: Smaller schools gain access to high-quality intelligence typically available to larger organizations.

• Implementation Tips:
  • Integrate CTIS data with Security Information and Event Management (SIEM) systems for automated alerting.
  • Use CTIS insights to enhance existing defences, such as firewalls and email filters.
  • Actively participate in the CTIS community to strengthen the overall network.

Building a Cybersecure Foundation

1. Invest in Cybersecurity Training

Phishing remains a significant threat. Comprehensive training programs for educators, administrators, and students are essential.

2. Protect Data Like Gold

Encryption, multi-factor authentication (MFA), and strict access control policies are critical to safeguarding sensitive information.

3. Upgrade Legacy Systems

Replace outdated systems where possible. For those that cannot be replaced, isolate them from broader networks and monitor for anomalies.

4. Adopt Zero-Trust Architecture

Zero-trust models ensure that no user or device is trusted by default, limiting attackers’ 7ability to move laterally within the network.
