The City of Columbia City data breach

What we know

The City of Columbia City is a municipal government entity responsible for providing essential public services and maintaining administrative records for its residents. As a local government body, the City collects and stores sensitive personal information required for tax administration, utility billing, public safety, and human resources management. This data breach was officially reported to the Oregon Attorney General in 2025, and the City has since issued formal notification letters to all individuals whose personal information may have been compromised. If you received this letter, it indicates that your private data was stored within the City’s systems during the time of the incident. We recommend reviewing the notification letter carefully to understand the specific scope of the exposure and the protective measures being offered.
