# Incident Report: St. Joseph City Cyberattack and Potential Data Exposure
## Executive Summary
The City of St. Joseph suffered a significant cyberattack in early June 2025 that severely crippled network services for an extended period. While the city initially reported vague "network issues," subsequent investigation confirmed a notable security incident, leading to over \$1 million in infrastructure upgrades. The primary concern is the potential exfiltration of sensitive data, possibly including records from the police and health departments, affecting thousands of residents.

- **Eradication:** Implied by subsequent security upgrades.
- **Recovery:** Restoring network services and implementing extensive upgrades to cybersecurity and technology infrastructure (costing >\$1M).
## Lessons Learned
- The extent of the compromise, particularly regarding sensitive departmental data (police, health), was not immediately clear, indicating potential gaps in visibility or rapid assessment capabilities.
- Initial communication (June 9) referred vaguely to "network issues" before confirming security concerns on June 26, suggesting a delayed acceptance or acknowledgment of a security incident.
## Recommendations
- Implement enhanced network monitoring and threat hunting capabilities capable of rapidly identifying and confirming cyber intrusion versus simple outages.
- Review data access controls, particularly segregation between standard city services and sensitive databases such as police and health records.
- Develop a clear, rapid communication plan for confirming security incidents versus standard IT issues.
