AT&T has discovered that a hacker accessed its systems and stole the phone call and text message records of nearly all its customers.
The company announced the security breach in a support document today.

We learned that AT&T customer data was illegally downloaded from our workspace on a third-party cloud platform. We started an investigation and engaged leading cybersecurity experts to help us determine the nature and scope of the issue. We have confirmed the access point has been secured.
Our investigation found that the downloaded data included phone call and text message records of nearly all of AT&T cellular customers from May 1, 2022 to October 31, 2022 as well as on January 2, 2023. These records identify other phone numbers that an AT&T wireless number interacted with during this time, including AT&T landline (home phone) customers. For a subset of the records, one or more cell site ID numbers associated with the interactions are also included.
At this time, we do not believe the data is publicly available. We continue to work with law enforcement in their efforts to arrest those involved. Based on information available to us, we understand that at least one person has been apprehended.

AT&T says that if your account was affected by the event, they'll contact you by text, email, or U.S. mail. They have also made it possible to get the phone numbers of your calls and texts in the downloaded data. More details about this process can be found at the link below...
