Spartanburg County Data Breach Affects Nearly 10,000 Residents in August 2025
In August 2025, Spartanburg County, South Carolina, detected unauthorized access to a portion of its computer network. While the breach did not disrupt county services, an investigation revealed that files containing sensitive information were copied without permission. By December 8, 2025, officials confirmed that 9,756 residents were impacted after reviewing the compromised data.
The breach involved onboarding files containing employee information. Spartanburg County notified affected individuals on December 23, 2025, offering complimentary identity monitoring as part of its response. The incident was remediated following its discovery, though details on the exact nature of the exposed data remain limited. The county had initially disclosed the breach in August but completed its full assessment months later.
