Schools are targeted through a mix of deliberate intrusions, social engineering and preventable errors. Verizon’s 2025 Data Breach Investigations Report (DBIR) recorded 1,075 Educational Services incidents, including 851 with confirmed data disclosure, during November 1, 2023–October 31, 2024. System Intrusion, Miscellaneous Errors and Social Engineering together made up 80% of breaches in that reporting sample—not a real-time census of every school attack.
What the education-sector data actually shows
The figures come from Verizon Business’s 2025 Data Breach Investigations Report. They describe incidents shared by report contributors and classified under Verizon’s methodology, so they indicate recurring patterns rather than the probability that any particular school will be breached.
| Measure | Educational Services result | How to read it |
|---|---|---|
| Incidents | 1,075 | Incidents in the DBIR’s November 1, 2023–October 31, 2024 sample |
| Incidents with confirmed disclosure | 851 | Cases in that sample where data exposure was confirmed |
| Three leading patterns | 80% combined | System Intrusion, Miscellaneous Errors and Social Engineering |
| Actors | 62% external; 38% internal | Actor categories reported by Verizon |
| Motives | 88% financial; 18% espionage | These categories can overlap; they do not total 100% |
Verizon’s summary table lists Miscellaneous Errors at 26% and Social Engineering at 17% of breaches. In a separate narrative treatment, it reports errors at 29% and identifies misdelivery as the leading error variety at 17%. Those values use different report contexts and should not be combined into one calculation.

Deliberate intrusion
System Intrusion covers an attacker gaining unauthorized access to systems or accounts. In the report’s relevant actions, hacking represented 36%. Stolen credentials were the leading hacking variety at 24%, meaning an attacker may not need to defeat a technical control if a valid password has already been captured or reused. Malware represented 42% of relevant actions, with ransomware the leading malware variety at 30%.
#1 Best Overall
Social engineering
Social engineering manipulates a person into taking an action that benefits the attacker—for example, opening a malicious attachment, entering a password on a fraudulent sign-in page or changing payment details. Phishing accounted for 77% of Social Engineering breaches in Verizon’s education data; that percentage applies only to the Social Engineering subset, not to all school breaches. Pretexting accounted for 7% of that subset.
Accidental error
An error is an unintended disclosure or change, such as sending a student record to the wrong recipient, exposing a shared folder or misconfiguring a service. Errors can occur without a malicious actor, although an attacker may later exploit the exposed information. They can also appear alongside intrusion or social engineering in the same incident.
Why schools are attractive targets
The Dark Reading analysis by Arielle Waldman describes an unusually broad attack surface: student devices, administrative accounts and network edges, often spread across campuses and cloud services. Practitioners interviewed for that article point to legacy systems, fragmented environments, constrained budgets and small security teams. These are practitioner observations, not measurements of every school.

Student and family records, staff identities, payment information and internal documents may sit in different systems with different administrators. A temporary account, an old application or a rushed email can therefore create a path that is difficult to monitor consistently.
Rank #3
Dave Hylender, Verizon’s associate director of threat intelligence, told Dark Reading that “Error has been on a slow but steady increase, while social engineering has been a bit more volatile, with highs and lows over the last few years.” KnowBe4 security awareness advocate James McQuiggan separately described social engineering as “the fastest-growing vector due to its low cost and high return for threat actors.” The latter is an expert opinion, not a DBIR statistic.
Mistakes that most often turn into exposure
Misdelivery
Addressing an email to the wrong person, attaching the wrong file or sharing a link with the wrong permission can disclose records without any malware. Use recipient checks, delayed sending for sensitive messages and access-controlled links rather than unrestricted attachments.
Weak account handling
Reused passwords, unprotected administrator accounts and excessive privileges make stolen credentials more valuable. Require multifactor authentication for staff and administrators, remove dormant accounts promptly and give each role only the access it needs.

Unmanaged devices and legacy services
Old servers, unsupported applications and personally managed devices may not receive consistent updates or logging. Maintain an inventory, prioritize internet-facing and identity systems for remediation and isolate systems that cannot yet be replaced.
Best Value
Rushed responses to convincing requests
Phishing and pretexting succeed when a request appears to come from a principal, payroll provider or technology administrator. Establish an out-of-band verification step for password resets, payment changes and requests for sensitive data; staff should know that verification is expected, not an accusation.

No product or training program is tested by the cited sources. Schools can compare safeguards by asking what risk each one reduces, which users and systems it covers, and whether staff can operate it reliably.
- Account takeover: multifactor authentication, password managers, phishing-resistant sign-in methods and rapid credential revocation.
- Accidental disclosure: recipient warnings, data classification, least-privilege sharing and review workflows for exports and mailing lists.
- Legacy or unmanaged systems: network segmentation, compensating monitoring, patch prioritization and a documented replacement schedule.
- Detection and recovery: centralized logs, alert ownership, tested offline backups and a practiced ransomware response plan.
- Coverage and sustainability: support for student and staff populations, clear ownership across campuses, manageable administration and costs that can be maintained after the initial rollout.
A practical response plan
- Map critical data and access. Identify where student, staff, financial and authentication data reside, who administers each system and which services are exposed to the internet.
- Protect identities first. Enforce multifactor authentication for privileged and externally accessible accounts, eliminate shared credentials and review dormant access.
- Reduce routine disclosure errors. Apply sensible sharing defaults, verify unusual requests through a second channel and add approval for bulk exports or payment changes.
- Contain high-risk technology. Segment legacy systems, patch internet-facing services and record exceptions with an owner and deadline.
- Prepare for ransomware and account compromise. Keep backups separated from production, test restoration and define who can disable accounts, isolate devices and notify affected parties.
- Measure and adjust. Review phishing reports, authentication alerts, unresolved vulnerabilities and recovery-test results with school leadership rather than treating annual training completion as the sole metric.
How to interpret changes in the numbers
Verizon says the Educational Services counts decreased from the prior edition but cautions that contributor mix and visibility may explain the change. A lower count therefore does not prove that attackers lost interest or that schools became safer. The report’s percentages are classifications within its sample: personal data appeared in 58% of breaches, internal data in 49%, other data in 35% and credentials in 12%. These data categories can overlap, so they should not be added together.
Recommended Free Tools
The most defensible conclusion is narrower: in the documented period, schools experienced substantial exposure through both hostile activity and ordinary process failures. Improving identity protection, verification, configuration discipline and recovery readiness addresses those paths without assuming that every incident has a single cause.
