Investigation notes
The Illinois Department of Healthcare and Family Services (HFS) is a government agency responsible for managing the state's Medicaid program and providing essential health coverage and child support services to Illinois residents. As a public entity overseeing sensitive healthcare and financial assistance programs, the department collects and maintains extensive personal data, including medical histories, Social Security numbers, and financial eligibility records. In 2025, the department officially reported a data breach to the Illinois Attorney General, indicating that unauthorized access to its systems may have compromised the personal information of individuals served by the agency. If you received a data breach notification letter, it confirms that your personal data was 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.
What our attorneys examine
A cyberattack does not excuse a company from protecting the information it holds. We look at whether ILLINOIS DEPARTMENT OF HEALTHCARE AND FAMILY SERVICES 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 Illinois.
