Description
On Thursday, August 6, the city of Mitchell’s computer network was shut down following a cybersecurity incident that affected a limited portion of its network. The shutdown resulted in restricted access to the city’s meeting agenda platform. City personnel were unable to post council meeting materials during the outage. The incident prompted an immediate response from municipal staff and external experts. No further technical details about the attack vector or malware were disclosed in the reporting.
On Wednesday evening, August 12, Mayor Jordan Hanson issued a written statement to the Mitchell Republic regarding the incident. In the statement he said the city had experienced issues with a limited portion of its network and, thanks to the quick response of employees and a team of experts, the network is now fully operational. He added that all online systems are operating as expected and thanked the public for their patience. Hanson explicitly declined to answer questions about whether any customer data had been leaked or compromised. The statement was released after city staff had regained the ability to post the agenda and documents for the Mitchell City Council meeting scheduled for Monday, August 17.
Mike Waldner, director of SecureSD and Project Boundary Fence at Dakota State University, told the Mitchell Republic that he could not discuss specifics of the Mitchell incident, warning that disclosure could aid bad actors. He noted that SecureSD collaborates with counties and most municipalities across South Dakota. SecureSD’s activities include funding vulnerability reduction, phasing out legacy firewalls, acquiring specialty security equipment and software, conducting real‑time email threat scanning, and providing employee cybersecurity training, incident response workshops, and incident response planning. The article does not indicate whether SecureSD was directly involved in the Mitchell response, but outlines the organization’s typical role in supporting local government cybersecurity. No additional information about the duration of the outage, the exact systems affected, or any potential data loss was provided in the source material.
