What's Happening?
The city of Greenville has concluded its investigation into a ransomware attack that occurred in August, confirming that no sensitive data was compromised. City officials announced on October 3 that the cyber incident originated from an unnamed third-party service provider, rather than employee error or phishing. The city collaborated with law enforcement and a third-party cybersecurity firm to assess and mitigate the attack. Although customers of Greenville Electric Utility System (GEUS) experienced service interruptions, GEUS systems were not targeted and remained secure. Access to GEUS's account database was temporarily disabled as a precaution, limiting online payment access. Payment systems were unaffected as they are managed by a separate cloud-based provider. All city services are now operational, and GEUS plans to resume regular billing and disconnections in October, with normal billing schedules expected by the end of November. The city's cyber insurance policy covered the ransom cost, ensuring no impact on local taxes.
Why It's Important?
The resolution of the ransomware attack in Greenville highlights the importance of cybersecurity measures and insurance in protecting municipal services and data. The incident underscores the vulnerability of third-party service providers and the need for robust cybersecurity protocols. By successfully mitigating the attack without compromising sensitive data, Greenville sets a precedent for other cities facing similar threats. The city's ability to restore services and maintain financial stability through cyber insurance demonstrates a proactive approach to managing cyber risks. This event serves as a reminder for municipalities to regularly review and strengthen their cybersecurity infrastructure to prevent future incidents.
What's Next?

Additionally, the event highlights the growing importance of cyber insurance in mitigating financial risks associated with cyberattacks, potentially influencing policy decisions and insurance offerings in the public sector.
