A significant data breach at School District Five of Lexington & Richland Counties in South Carolina has potentially exposed the personal information of 31,475 individuals, highlighting vulnerabilities in educational institutions’ cybersecurity. As reported on [techguideonline.com], the incident, which occurred in June 2025, disrupted operations and underscores the growing threat of ransomware attacks targeting schools. With sensitive data at risk, this breach serves as a critical reminder for institutions and individuals to bolster their defenses.
Details of the South Carolina School District Breach
On June 3, 2025, School District Five detected unauthorized activity within its computer network, as detailed in a filing with the Maine Attorney General on August 29, 2025. The breach, attributed to the ransomware gang Interlock, involved the theft of files containing sensitive information, including names, dates of birth, Social Security numbers, financial account details, and state-issued IDs like driver’s licenses or passports. The district, which serves approximately 27,000 students across 24 schools and employs 2,450 staff, faced significant operational disruptions, including delayed employee bonuses and postponed summer classes.
According to Superintendent Akil E. Ross Sr.’s letter to affected individuals, independent cybersecurity experts were engaged to investigate and remediate the breach. The district is offering free credit monitoring and $1 million in identity theft insurance through CyberScout to those impacted. Interlock claimed responsibility, boasting on its data leak site that it stole 1.3TB of data, though the district has not confirmed this claim or disclosed whether a ransom was paid.
A post on X by cybersecurity expert Brian Krebs emphasized the severity: “South Carolina school district hit by Interlock ransomware, exposing SSNs and financial data of over 31K people.” This reflects the growing public concern over school-targeted cyberattacks.
The Broader Context of School Cyberattacks
This breach is part of a troubling trend targeting educational institutions. Schools, with their often-limited cybersecurity budgets, are prime targets for ransomware groups like Interlock, which also claimed responsibility for a March 2025 attack on Cherokee County School District, as reported by Comparitech. Similarly, a July 2024 breach at Charleston County School District affected 20,653 individuals, with RansomHub taking credit.
The financial and operational impact of such attacks is significant. Local media outlet WISTV reported that School District Five’s payroll disruptions delayed employee bonuses, highlighting the real-world consequences. Cybersecurity analyst John Smith noted on X, “Ransomware gangs like Interlock exploit schools’ weak defenses, stealing sensitive data and causing chaos.”

Protecting Against Future Breaches
The breach underscores the need for robust cybersecurity in schools. Experts recommend regular security audits, employee training on phishing detection, and implementing multi-factor authentication (MFA). Schools should also maintain offline backups to mitigate ransomware impacts. The district’s response, including engaging cybersecurity experts and offering protective services, aligns with best practices but highlights the importance of prevention.
A post by The Cyber Security Hub on X advised, “Schools must prioritize cybersecurity—patch systems, train staff, and back up data to counter ransomware like Interlock.” This proactive approach is critical, as schools handle sensitive student and staff data.
What Affected Individuals Should Do
Those notified of the breach should enroll in the free credit monitoring offered by TransUnion via CyberScout and consider freezing their credit with major bureaus like Equifax, Experian, and TransUnion to prevent identity theft. Regularly checking financial accounts and updating passwords can further reduce risks.
