AT&T Data Breach: ‘Nearly All’ Wireless Customers Exposed in Massive Hack

A massive data breach at AT&T exposed call and text interaction records for nearly all its wireless customers between May 2022 and January 2023. The breach is linked to recent attacks on Snowflake customers, where data was illegally downloaded from AT&T's workspace on a third-party cloud platform. The stolen data includes telephone numbers, call durations, and cell site identification but lacks personal identifiers like Social Security numbers. AT&T asserts the breach has not materially impacted its operations and believes the data has not been publicly released. At least one suspect has been apprehended in connection to the breach.
