Investigation notes
The City of Hayward is a municipal government entity responsible for providing essential public services to its residents and managing city operations. As a government body, the City typically collects and stores sensitive personal information including Social Security numbers, driver’s license numbers, tax records, and utility account details necessary for administrative and public safety functions. This data breach was officially reported to the California Attorney General in 2025, and the City has since issued formal notification letters to all individuals whose personal information may have been impacted. If you received such a letter, it indicates that your sensitive records were involved in this security incident, and you should review the provided documentation carefully to understand the specific risks to your personal data.
What our attorneys examine
A cyberattack does not excuse a company from protecting the information it holds. We look at whether City of Hayward 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 California.

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.
