Investigation notes
The City of Houston is a municipal government entity responsible for providing essential public services to its residents. As a government agency, it collects and maintains sensitive personal information, including tax records, utility account details, employment files for municipal staff, and various public safety or administrative documents. In 2025, the City of Houston officially reported a data security incident to the Texas Attorney General, indicating that unauthorized access to its systems may have occurred. If you received a formal data breach notification letter, it means the city has identified that your personal information was potentially involved in this incident. This notice is intended to inform you of the nature of the event and the steps you should take to protect your identity and financial security.
What our attorneys examine
A cyberattack does not excuse a company from protecting the information it holds. We look at whether City of Houston 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 Texas.

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.
