Investigation notes
Union County, Ohio, operates as a local government entity responsible for managing public records, tax administration, and various social services for its residents. In the course of these governmental operations, the county typically collects and stores sensitive personal information, including Social Security numbers, residential addresses, and financial data related to property taxes or public assistance programs. This data breach was officially reported to the New Hampshire Attorney General in 2025, confirming that unauthorized access to certain files occurred.

We recommend reviewing the letter carefully to understand the specific steps the county is taking to support affected individuals.
What our attorneys examine
A cyberattack does not excuse a company from protecting the information it holds. We look at whether Union County, Ohio 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 New Hampshire.
