Threat-actor claim — not a regulatory filing

This row is a claim by the ransomware group Interlock on its public extortion blog. It has not been validated by the victim or any regulator. Treat attribution and counts as the threat actor's assertion until a regulatory filing or victim disclosure corroborates them.

The school nurse has the expertise to identify, assess, plan, implement, and evaluate the health needs of the individual student and the school community. School nurses, grounded in ethical and evidence-based practice, are leaders who link health and education, provide care coordination, advocate for quality student-centered care, and collaborate to develop systems that enable individuals and communities to reach their full potential. (Adopted by the National Association of School Nurses Board of Directors, February 2017). But Cherokee County School District, for all its talents, is rather negligent about the security of its network. We present to your attention the personal data of employees, financial and tax reports.
