The well-known threat actor known as ShinyHunters has just blown up news by posting an offering for customer data on 70 million AT&T customers that includes their SSN and date of birth. The listing appeared on a popular forum where data is sold and traded. The starting price requested is $200,000.00 with a minimum step of $30,000.00 in bidding. Unlike the T-Mobile which was described as having some hacktivist purpose, the AT&T incident appears purely for commercial purposes. AT&T did not immediately reply to a request for comment on the listing and claims.  Technically, then, this claim is still unconfirmed, but I will be surprised if it is not confirmed. This post will be updated when a response from AT&T is received.
