AT&T is warning of a massive data breach where threat actors stole the call logs for approximately 109 million customers, or nearly all of its mobile customers, from an online database on the company's Snowflake account.
In a Friday morning Form 8-K filling with the SEC, AT&T says that the stolen data contains the call and text records of nearly all AT&T mobile clients and customers of mobile virtual network operators made from May 1 to October 31, 2022 and on January 2, 2023.
AT&T customers can follow the links provided on this FAQ page to check if their phone number's data was exposed and to download the data associated with their number that was stolen.
As of today, AT&T says it has no evidence the accessed data has been made publicly available and says the incident is not related to the 2021 data breach AT&T confirmed earlier this year impacted 51 million customers.
Snowflake is a cloud-based database provider that allows customers to perform data warehousing and analytics on large volumes of data.
