XFinity Data breach - customer information leaked

Xfinity - can you please confirm that if a customer did not receive a notification of your recent data breach that their data was not subject to the breach?  https://www.kgw.com/article/news/nation-world/comcast-xfinity-breach-2023/507-7ab12e31-0d37-419a-8d60-8af328cad348

The article indicates that Xfinity should have asked all customers to change their passwords but I have not been asked to to so.  Additionally, will Xfinity be offering details on what customer information was disclosed and if those customers will be provided with free credit monitoring?
