The Top 5 Cybersecurity Threats Facing School Districts And How to Address Them

Cybersecurity has quickly become one of the most pressing concerns for K–12 school districts. With sensitive student data, growing reliance on cloud-based learning platforms, and a steady rise in ransomware attacks, districts are prime targets for cybercriminals. Unlike large corporations, schools often operate with limited budgets and stretched IT teams, making proactive planning essential.

Consider this: in 2022, the Los Angeles Unified School District (LAUSD) was hit with one of the largest ransomware attacks in education history. The breach disrupted access for more than 400,000 students and forced the district to shut down critical systems while federal agencies intervened. If a district the size of LAUSD can be brought to its knees, what does that mean for smaller districts with fewer resources?

Below, we break down the top five cybersecurity threats school districts face—what they are, how they occur, what districts can do ahead of time, how to respond if the threat occurs, and how to improve resilience moving forward.

1. Ransomware Attacks

What It Is:
Ransomware is malicious software that locks or encrypts a district’s systems until a ransom is paid. Attackers often target K–12 because they know downtime disrupts learning, creating urgency to pay.

How It Happens:

• Phishing emails with malicious attachments.

• Exploiting outdated software or unpatched systems.

• Remote desktop protocol (RDP) attacks where weak passwords give hackers access.

Prepare Ahead of Time:

• Maintain regular, encrypted data backups (stored offline).

• Patch and update systems promptly.

• Use multifactor authentication (MFA) for staff and admin accounts.

If It Happens:

• Isolate infected systems immediately.

• Notify law enforcement and state cybersecurity response centers.

• Implement your incident response plan—communication is critical to staff and families.

Improvement Steps:

• Conduct tabletop exercises simulating ransomware.

• Audit backup recovery speed annually.

• Adopt endpoint detection and response (EDR) tools.

Case in Point: In 2023, Minneapolis Public Schools was hit by a ransomware attack in which the Medusa group demanded $1 million, threatening to leak sensitive student and staff data. The district refused to pay, and much of the data was later published — underscoring the importance of offline backups and crisis communication.

2. Phishing & Social Engineering

What It Is:
Phishing tricks staff, teachers, or even students into clicking links, downloading malware, or handing over login credentials. Social engineering extends beyond email—it can include fake tech support calls or impersonation of trusted partners.

How It Happens:

• Emails that mimic district leadership, vendors, or government agencies.

• “Urgent” messages requesting password resets or payments.

• Calls posing as IT staff asking for credentials.

Prepare Ahead of Time:

• Regular phishing awareness training for staff and older students.

• Use email filters, sandboxing, and banner warnings for external senders.

• Apply domain-based message authentication (DMARC) to prevent spoofing.

If It Happens:

• Change compromised passwords immediately.

• Monitor accounts for unusual activity.

• Report the phishing attempt to IT, and if sensitive data was exposed, notify parents and staff per FERPA guidelines.

Improvement Steps:

• Launch quarterly phishing simulation tests.

• Enforce least-privilege access (staff only access what they need).

• Create a quick “Report Phish” button in email clients.

Case in Point: In 2025, Broken Bow Public Schools in Nebraska fell victim to a sophisticated phishing scam that redirected a construction payment worth $1.8 million into a fraudulent account. The email looked legitimate, carrying false payment instructions that seemed to come directly from a trusted vendor. By the time the fraud was uncovered, hundreds of thousands of dollars were gone—though quick action with banks and law enforcement helped the district recover roughly $700,000.

 

What made this attack successful? A lack of verification procedures. No one picked up the phone to confirm the new instructions before transferring funds. Could a simple five-minute call have saved the district $1.1 million? Absolutely.

3. Data Breaches & Student Privacy

What It Is:
Data breaches occur when unauthorized actors access sensitive information—student records, Social Security numbers, health data, or financial records. In education, such breaches often violate FERPA and state laws.

How It Happens:

• Exploiting unprotected databases.

• Breached third-party vendors (learning apps, payroll, transportation systems).

• Lost or stolen devices without encryption.

Prepare Ahead of Time:

• Encrypt all sensitive student and staff data.

• Vet third-party vendors for compliance with FERPA and state privacy laws.

• Require device encryption and strong authentication policies.

If It Happens:

• Contain the breach and secure exposed systems.

• Conduct forensic analysis to determine scope.

• Notify affected families and provide credit monitoring if required.

Improvement Steps:

• Maintain a district-wide data inventory and retention policy.

• Apply zero-trust network principles.

• Develop vendor risk management programs with clear accountability clauses.

Case in Point: In early 2022, Illuminate Education — a widely used ed-tech vendor — experienced a data breach that exposed personal information of over a million students. While sensitive academic, demographic, and behavioral data were compromised, Social Security numbers and financial data were not. Parents asked: could this have been prevented, and is trusting a third-party vendor worth the risk?

4. Distributed Denial-of-Service (DDoS) Attacks

What It Is:
A DDoS attack overwhelms a school’s network with massive traffic, making online platforms, testing systems, or district websites inaccessible.

How It Happens:

• Attackers use botnets of infected devices to flood networks.

• Sometimes students launch DDoS attacks to avoid exams or disrupt classes.

Prepare Ahead of Time:

• Partner with your internet service provider (ISP) for DDoS mitigation.

• Implement network traffic monitoring and anomaly detection.

• Establish backup internet connections for critical operations.

If It Happens:

• Contact ISP immediately to reroute or filter traffic.

• Switch to backup internet channels if available.

• Pause online testing or remote learning activities temporarily.

Improvement Steps:

• Test DDoS response drills.

• Deploy cloud-based DDoS protection services.

• Educate students on the legal consequences of launching such attacks.

Case in Point: In September 2020, Miami-Dade County Public Schools—one of the largest districts in the nation—saw its first week of online learning thrown into chaos by a combination of DDoS attacks and software glitches on the district’s new “My School Online” platform. For days, tens of thousands of students couldn’t log in, teachers couldn’t reach their classes, and lessons stalled. At one point, the superintendent admitted: “We are currently under a cyberattack.”

The disruption was so severe that law enforcement intervened, and a 16-year-old student was later arrested for orchestrating some of the attacks. The incident raised an urgent question: what happens when a district’s entire digital infrastructure collapses under pressure? Learning—and accountability—grind to a halt

5. Insider Threats

What It Is:
Not all threats come from outside. Insider threats occur when staff, contractors, or even students misuse access—intentionally or accidentally—to harm systems or expose data.

How It Happens:

• Disgruntled employees stealing or leaking data.

• Staff unintentionally misconfiguring systems.

• Students finding loopholes in access controls.

Prepare Ahead of Time:

• Limit access based on job role (least-privilege principle).

• Monitor user activity logs for unusual behavior.

• Require strong offboarding processes when employees leave.

If It Happens:

• Revoke compromised accounts immediately.

• Investigate whether it was malicious or accidental.

• Provide transparent communication to stakeholders if data is involved.

Improvement Steps:

• Use identity and access management (IAM) tools.

• Rotate privileged credentials regularly.

• Strengthen cybersecurity culture through regular training and ethics reminders.

Case in Point: In early 2025, Fort Thomas Independent Schools in Kentucky reported a data breach after a malicious application gained access to a staff mailbox for months without detection. The intrusion exposed personal records dating back years, including Social Security numbers, insurance details, and addresses.

While this wasn’t caused by a former employee account, the lesson is the same: when access isn’t carefully monitored or promptly revoked, sensitive systems can remain vulnerable. If a single overlooked account can open the door to a breach, what damage could an unchecked former employee do?

Conclusion: Building Cyber Resilience in Education

School districts are no longer just educational institutions—they are digital ecosystems handling sensitive personal data at scale. While no system is 100% secure, preparation, layered defenses, and quick response can minimize damage.

Key Takeaways for Leaders:

• Plan ahead: Incident response, backups, and vendor vetting are non-negotiable.

• Respond effectively: Clear communication with staff, parents, and students builds trust during a crisis.

• Improve continuously: Each incident—whether real or a drill—should lead to stronger defenses.

Cybersecurity is a shared responsibility across administrators, teachers, parents, and students. By anticipating threats and practicing resilience, districts can safeguard both learning continuity and the trust of their communities.
