Education institutions faced an average recovery cost of $2.26 million following ransomware attacks in 2026. This retrospective report details how identity-based techniques have become the primary method for breaching school systems globally.
Why it matters
Schools represent high-value targets because they manage large volumes of sensitive personal data while often operating under significant resource constraints. The resulting incidents frequently lead to leadership turnover and sustained operational stress for staff.
Data encryption rates in lower education increased to 61% in 2026, up from 29% in 2025. Attackers successfully utilized identity-based techniques in 85% of these incidents.
The details
Attackers primarily gained unauthorized network access through identity-based methods, including malicious email, phishing, compromised credentials, and brute force attacks. Once inside, they targeted data for encryption, with 77% of lower education and 69% of higher education institutions eventually restoring systems from backups. The high frequency of these attacks has triggered broader organizational consequences, including stress-related staff absences in 39% of reporting institutions.
Timeline
In 2025, lower education data encryption occurred in 29% of ransomware cases.
During the first quarter of 2026, the research team conducted the global survey.
By 2026, the data encryption rate for lower education institutions had risen to 61%.
The Tech Race
The shift toward identity-based ransomware delivery signals an escalation in the race between defensive credential monitoring and automated exploitation tools. Educational entities remain particularly vulnerable as they continue to refine their backup strategies against these evolving vectors.
School administrators and IT staff face a growing necessity to implement rigorous identity-based security controls to prevent credential-based breaches. Over 25% of affected institutions required one to three months to fully restore normal operations following an incident.
The takeaway
The sharp rise in encryption rates underscores that perimeter security is insufficient against modern identity-focused ransomware campaigns. Future resilience metrics will likely hinge on the speed of recovery and the effectiveness of secondary identity authentication measures.
