What our attorneys examine
A cyberattack does not excuse a company from protecting the information it holds. We look at whether ILLINOIS DEPARTMENT OF HUMAN 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 IL.

Attorney advertising. An incident file reflects a public regulator filing and our review of it; it does not mean a lawsuit has been filed or that the company did anything unlawful. Submitting a review request does not create an attorney-client relationship.
