Description

On Thursday, August 6, 2026, the city of Mitchell shut down its computer systems after detecting a cybersecurity incident. The incident involved a hack of the city’s email system that occurred in early August. As a result of the breach, email services became unreliable and several city meetings were postponed. The shutdown limited access to the city’s meeting agenda platform. No further details about the specific malware or attack vector were disclosed in the sources.

Mayor Jordan Hanson issued a written statement on Wednesday evening, August 12, 2026, to the Mitchell Republic, noting that the city had experienced issues with a limited portion of its network. He credited the quick response of city employees and a team of experts for restoring operations. Hanson stated that, after the response, the city was fully operational and all online systems were operating as expected. He thanked the public for their patience during the incident. Hanson did not answer questions about whether customer data had been leaked or compromised.

By August 13, 2026, the city reported that its computer network was back up and running. City staff were able to post agenda and documents for the Mitchell City Council meeting scheduled for Monday, August 17, 2026. Mike Waldner, director of SecureSD and Project Boundary Fence at Dakota State University, declined to discuss specifics of the Mitchell incident or his involvement. The sources do not indicate any ransom payment or confirmation of data loss. No further updates were provided in the sources.
