Investigation notes
The City of Michigan City, Indiana, is a municipal government entity responsible for providing public services to its residents and managing administrative operations. As a local government body, the City typically collects and maintains sensitive personal information, including payroll data for employees, tax records, utility account details, and various permit or licensing applications. This security incident was officially reported to the Indiana Attorney General in 2025, confirming that unauthorized access to certain systems occurred.

We encourage you to carefully review the notification letter provided by the City to understand the specific scope of the exposure and the recommended protective measures.
What our attorneys examine

We look at whether City of Michigan City IN 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 Indiana.
