Pierce County Library System data breach investigation

Investigation notes

The Pierce County Library System is a public institution that provides educational resources, digital media, and community services to local residents. As a public service entity, the library typically collects and stores sensitive personal information to manage patron accounts, including registration details, borrowing histories, and contact information. In 2025, the organization officially reported a data security incident to the Indiana Attorney General, confirming that unauthorized access to their systems occurred. If you have received a formal data breach notification letter from the library, it indicates that your personal information was likely stored within the affected environment. This notice is intended to inform you of the incident and provide guidance on the steps you should take to protect your identity and monitor your accounts for suspicious activity.
