The Rising Threat: Cyberattacks on Schools

·

In recent years, schools, colleges and other educational settings have become increasingly frequent targets for cyberattacks. These incidents range from data breaches and ransomware to insider misuse and distributed denial-of-service (DDoS) attacks. According to the UK Government’s Cyber Security Breaches Survey 2025, 60 % of secondary schools reported at least one breach or attack in the past 12 months, and 44 % of primary schools did likewise.  Meanwhile, at the same time, alarming evidence is emerging that many of these attacks are not external foes alone a substantial share are carried out from within, by students or staff. 

A recent, stark example came just days ago, when a hacking group calling itself Radiant announced it had breached the UK nursery chain Kido International, compromising personal data of over 8,000 children. Names, photos, addresses and contact information were published as “proof” of the breach, and the group threatened to leak further information unless paid.  While this instance targets early years rather than schools per se, it underscores the escalation of threat levels across all educational settings. 

Notably, attacks on school infrastructure are not only isolated to data theft. In Scotland, for instance, a ransomware attack on the West Lothian Council’s education network disrupted schooling across multiple schools.  In Edinburgh, a spear-phishing attack targeted the local education department and interfered with students’ access to exam revision resources at a critical time. 

The trend is clear: educational institutions are under growing siege. But why?

Why Schools Are Attractive Targets

To understand why schools are increasingly vulnerable, one must look at systemic and practical factors.

1. Valuable Data & Sensitive Information

Schools hold a trove of personal and sensitive data: student and staff records, medical histories, safeguarding and welfare notes, financial information, exam results, contact details. For malicious actors, this is prime material for identity theft, extortion, sale on darknet markets, or reputational damage.

Even early years providers, like the Kido example, handle data on very young children which makes the consequences more sensitive and the public backlash more severe. 

2. Often Weaker Defences Than Business or Government

Educational institutions typically operate under constrained budgets and with limited IT/security staffing. Many schools depend on generalist IT support rather than dedicated cybersecurity teams. Awareness of national guidance (e.g. the NCSC’s “10 Steps to Cyber Security”) or certification schemes (Cyber Essentials) is lower in primary and secondary schools than in business sectors. 

In the 2025 survey, while most schools had some kind of cybersecurity policy, the sophistication and maturity of those policies lag behind those of larger organisations. 

Moreover, many schools depend on external providers for software, learning platforms, cloud services or network infrastructure. If any of those third parties is breached, it can cascade into the school’s systems a form of supply chain vulnerability. 

3. High Usage, Many Users, Numerous Devices

Schools are busy digital environments: networks connecting many devices (laptops, tablets, smartboards, printers, IoT devices), many kinds of software and platforms (learning management systems, school management systems, remote learning tools), and high volumes of data traffic. Each connection is a potential vector.

Even simple things like weak passwords, shared accounts, misconfigured access rights, or devices left unlocked can open doors for attackers. In the ICO’s analysis of school data breaches, 30 % of insider attacks involved students guessing weak passwords or finding them on paper notes. 

4. Insider Threat – Students and Staff

One of the more sobering findings is the role of insiders especially students in school cyber incidents. The UK ICO, reviewing data from January 2022 to August 2024, found that 57 % of school insider cyber incidents were caused by students. 

Some of these arise from curiosity, dare culture, pranks or desire for notoriety. Others stem from attempts at more serious sabotage or illicit gain. As one commentator put it, “Teen hackers are not breaking in, they are logging in.” 

Staff can also be unwitting participants in breaches for example by sending data to personal devices, accessing more data than needed, or misconfiguring access rights. 

5. Critical Timing & Operational Sensitivity

The timing of attacks is sometimes strategic: just before exams, during results release, or during transitions or holidays, when systems are under stress or changes are occurring. Disruption at such times causes maximal damage and pressure.

The Impacts: What Happens When Schools Are Breached

When a school is hit by a cyberattack or breach, the fallout can be wide and deep. Here are some of the key consequences.

Disruption to Teaching & Learning

Perhaps the most immediate effect is disruption to normal operations:

  • Systems go offline (e.g. student management systems, virtual classrooms, internet access).
  • Lessons cannot proceed as planned; remote learning platforms may be inaccessible.
  • Exams, assessments or revision resources may be compromised or unavailable (as in Edinburgh). 
  • Administrational tasks such as attendance, scheduling, communication with parents, reporting may be blocked.
  • Staff scramble to work around IT failure, often resorting to paper systems, which slows processes and increases errors.

Where the attack is serious, schools may even be forced to close temporarily or restrict in-person operations.

Data Loss, Exposure & Privacy Harms

Data theft is a core motive in many of these attacks. The implications are:

  • Identity theft, fraud, or misuse of personally identifiable information (PII).
  • Exposure of sensitive data (e.g. safeguarding notes, medical conditions, family contact data).
  • Legal and regulatory consequences under data protection laws (e.g. UK GDPR).
  • Loss of confidence and reputational harm to the institution.

In the Kido example, hackers published sample data of children, which is especially alarming given the age of those affected. 

Financial Costs & Recovery Burden

Recovering from a cyberattack is expensive:

  • Costs to investigate and forensically analyse the breach.
  • Remediation: patching systems, rebuilding networks, restoring data from backups.
  • External expertise: hiring cybersecurity firms, legal counsel, auditors.
  • Potential ransom payments (though many authorities discourage paying).
  • Indirect costs: staff time diverted from education to recovery, lost teaching days, reputational costs, potential fines.

Even in other public sectors, the financial burdens are stark for example, the Co-op lost £206 million in revenue following a cyberattack.  While that scale is beyond a school, it signals what is at stake in large-scale breaches.

Regulatory, Legal and Accountability Risk

Educational institutions are subject to data protection and privacy laws. If a breach is found to be due to negligence, the school may face regulatory sanctions, penalties, or be required to notify affected individuals formally.

There is also the matter of accountability governing bodies, trustees, headteachers and ICT managers may face scrutiny over their duty of care and risk management. A breach can tarnish trust with stakeholders: parents, students, staff, local authorities and the wider community.

Psychological & Reputational Damage

For students, parents and staff, a breach can lead to anxiety, stress, concern over privacy, and loss of confidence in the school’s capacity to protect them. The breach may be widely publicised, harming the school’s reputation, affecting future admissions, partnerships or funding.

In particular, when children’s data including images or contact details are exposed, there is a strong emotional response from families and communities.

Educational Equity & Trust Erosion

Repeated cyber incidents may deepen inequalities: schools in disadvantaged areas with weaker budgets or less access to cybersecurity expertise may be less resilient, leading to a widening gap in safety and trust.

If families lose confidence in the digital platforms schools use, uptake of innovations (blended learning, remote platforms) may suffer. It undermines trust in digital transformation in education.

Recent Case Studies & Illustrative Incidents

To make the risks more concrete, here are a few illustrative examples (beyond Kido) drawn from recent years.

  • West Lothian Education Network (Scotland): In May 2025, the education network fell victim to a ransomware cyberattack. The event remains under criminal investigation. 
  • Edinburgh Education Department: A spear-phishing attack prevented access to exam revision systems for over 2,500 pupils close to exam period, forcing emergency password resets and weekend school attendance. 
  • Insider Threat Incidents in UK Schools: The ICO found that 57 % of insider attacks in schools come from students (for example by guessing weak passwords or exploiting known credentials). 
  • International example – Miami-Dade Schools DDoS (2020): A 16-year-old launched a DDoS attack on the school district’s IT systems, forcing network disruption for three days.  While not recent, it illustrates how even relatively unsophisticated attacks can wildly disrupt schooling.

These stories show that threats can be external, internal, or hybrid; that timing matters; that people (not just technology) are often the weak link; and that recovery is often resource intensive.

Strategies for Prevention, Mitigation and Recovery

Given the stakes, what can schools and educational organisations do to defend themselves, reduce risks, and respond effectively when attacks happen? Below are a series of recommended practices some more advanced than others but all grounded in current best thinking.

1. Leadership, Governance & Risk Management

  • Board and senior leadership buy-in cybersecurity must be seen as part of the strategic risk framework.
  • Clear policies and procedures defined responsibility for incident response, roles, data governance, acceptable use.
  • Regular risk assessments to identify vulnerabilities (technical, procedural, human) and prioritise mitigation.
  • Supplier / third-party risk oversight vet the security posture of cloud providers, software vendors, learning platforms.
  • Budgeting for resilience invest in cybersecurity tools, staff, training and backup systems proportionally.

2. Basic Cyber Hygiene & Technical Controls

  • Patch management & software updates ensure all systems and devices are regularly updated.
  • Strong authentication use multi-factor authentication (MFA) wherever possible, including for staff and admin accounts.
  • Access control and least privilege restrict access rights to only those needed.
  • Network segmentation separate critical systems from public or student networks.
  • Regular backups maintain offline, immutable backups, and test restore processes frequently.
  • Intrusion detection and monitoring deploy logging, alerting and threat detection systems.
  • Use of security standards e.g. framework guidance like NCSC’s “10 Steps to Cyber Security,” Cyber Essentials certification.
  • Device protection antivirus, endpoint protection, apply encryption (e.g. on laptops, USBs).
  • Secure configurations default credentials changed, disable unused services, lock down remote access.

3. Awareness, Training & Culture

  • Staff training and refresher courses phishing awareness, safe email practices, data handling, secure remote access.
  • Student education and digital citizenship teach students about ethical use, personal cybersecurity, and consequences of misuse.
  • Simulated phishing exercises test and reinforce vigilance.
  • Reporting culture users should feel comfortable reporting suspicious incidents or near-misses without fear.

4. Incident Response & Business Continuity Planning

  • Incident response plan clearly documented steps for detection, containment, analysis, communications, restoration.
  • Defined roles and escalation paths who leads response, external contacts (e.g. law enforcement, regulators).
  • Communication plan templates and protocols for notifying stakeholders (parents, staff, authorities).
  • Tabletop exercises and drills practise responses to breach scenarios (e.g. data leak, ransomware, DDoS).
  • Redundancy and fallback systems alternative ways to teach and communicate when IT is down.
  • Legal and forensic support ready arrangements with external cybersecurity firms, legal counsel, forensics, insurers.

5. Post-incident Recovery & Learning

  • Post-mortem analysis what failed, how to improve, lessons learned.
  • Strengthening controls implement fixes, patch root causes, close gaps.
  • Communication and transparency reassure affected parties, maintain trust through openness.
  • Continuous improvement cyber risk is dynamic, so defence should evolve accordingly.

Challenges and Realities

Implementing the above is easier said than done; schools face constraints and trade-offs. Here are some of the ongoing challenges:

  • Limited budgets and resources especially for smaller or underfunded schools, securing dedicated IT/security personnel is hard.
  • Competing priorities leadership may prioritise pedagogical, curriculum, staffing needs over cyber investment unless a breach forces the issue.
  • Skill shortages cybersecurity professionals are in demand; it can be hard for schools to compete.
  • Balancing usability and security overly restrictive controls can impede teaching, learning or admin workflows.
  • Legacy systems and complex infrastructure older hardware, mixed environments, or bespoke systems can be difficult to secure.
  • Human behaviour no matter the tech, users make mistakes. Insider threat, phishing, social engineering remain persistent.
  • Regulation, liability and uncertainty complexity in managing reporting obligations, legal exposure, evolving cyber laws.

Despite these hurdles, the potential cost of inaction in disruption, harm, reputation, trust and legal consequences is too great to ignore.

Why This Matters Deeply: The Bigger Picture

The cyberattack trend in schools is not just a technical issue it strikes at the heart of a safe, stable, trusted environment for education. Some broader implications:

  • Protection of children and vulnerable individuals: Exposing sensitive student data crosses ethical lines; schools have a duty of care.
  • Erosion of trust: Parents, students and staff expect schools to safeguard personal information. Breaches undermine that trust.
  • Threat to innovation in education: As schools adopt more technology (digital learning, AI tools, cloud platforms), the risk surface expands; fear of cyberattacks may slow adoption of beneficial tools.
  • Widening inequity: Schools in affluent areas may better invest in resilience, whereas under-resourced schools remain vulnerable, furthering the digital divide.
  • National security and infrastructure resilience: Education systems are part of the national critical infrastructure mosaic; widespread breaches could be orchestrated or state-sponsored.
  • Cultivating ethical cyber skills: The fact many attacks originate from students suggests a need to channel youthful technical curiosity into positive pathways (ethical hacking, cybersecurity education) instead of destructive acts.

Toward a More Secure Future: Recommendations & Call to Action

To shift the balance from reactive response to proactive resilience, here are a few high-level recommendations for stakeholders (governments, educational bodies, schools, parents, students):

  1. National coordination & support Governments and education ministries should offer subsidies, grants or shared cybersecurity services to schools, especially smaller ones.
  2. Mandated standards / guidance Set baseline cybersecurity requirements for schools (minimum technical controls, incident response readiness, reporting obligations) rather than leaving everything voluntary.
  3. Cybersecurity as part of curriculum Embed real cyber awareness, ethics and safety lessons for students, so they understand their role and the consequences of misuse.
  4. Shared services and economies of scale Encourage school networks, local authorities, multi-academy trusts to pool cybersecurity resources, expertise, monitoring, and incident response capacity.
  5. Encourage ethical hacking opportunities Provide programmes (e.g. junior “capture the flag”, ethical hacking clubs) to engage students positively rather than illicitly.
  6. Continuous training and community of practice Build networks among school IT leads, share lessons learned, best practices, and threat intelligence.
  7. Research, monitoring and adaptation Invest in ongoing research on threats to education, new technologies (e.g. AI, generative models, supply chain threats), and update guidance accordingly.
  8. Transparency and accountability Promote openness about incidents (within legal bounds), lessons learned, and rebuild community trust after breaches.

Conclusion

Cyberattacks on schools are no longer hypothetical or occasional they are a growing and serious threat. Recent cases in the UK and abroad highlight how even early years settings and local education departments can be compromised, exposing sensitive data, disrupting teaching, imposing significant recovery burdens, damaging reputations, and undermining trust.

Schools are attractive targets because they house valuable data, often operate with weaker defences, manage many devices and users, and sometimes suffer insider misuse. The consequences of a breach ripple across students, staff, parents, and the educational mission itself.

Yet the path forward is not hopeless. Through strong leadership, sensible technical controls, awareness and training, incident planning, and shared support, schools can improve their resilience. But this must be a sustained, strategic effort not a one-off fix.
