Investigation notes

The Sonoma County Department of Emergency Management is a government agency responsible for coordinating disaster preparedness, response, and recovery efforts for the region. As a public entity, the department maintains sensitive records that often include personal identification, contact details, and emergency assistance documentation for county residents. This data breach was officially reported to the California Attorney General in 2026, confirming that unauthorized access to these systems occurred. If you have received a formal data breach notification letter from the department, it indicates that your personal information may have been compromised during this incident. We recommend reviewing the letter carefully to understand the specific scope of the exposure and the identity monitoring services being offered to help protect your information.

What our attorneys examine

A cyberattack does not excuse a company from protecting the information it holds. We look at whether Sonoma County Department of Emergency Management used reasonable security, how long it kept the data, and how quickly it told the people affected. Those questions decide whether a class action or individual claim is possible. Read more on how ransomware lawsuits work, or browse other incident files in California.
