The City of McMinnville reported a data breach that exposed sensitive information, including Social Security and driver's license numbers, affecting individuals whose data was accessed between June 1 and July 18, 2026. The breach was discovered on July 15, but formal notification to affected individuals was delayed until September 29, exceeding the 45-day legal requirement in Oregon. A ransomware group named RansomHouse claimed responsibility for the attack, which involved unauthorized access to various city records, including police and human resources information. Local cybersecurity expert Chuck Dornon confirmed the ease of accessing these records on the dark web, describing it as a 'treasure trove of information.' The city has since begun notifying affected individuals and is enhancing its data protection policies.
