AT&T revealed a massive hack affecting nearly all wireless subscribers. Customer call and text records were breached from as early as May 2022, and the stolen data includes phone numbers and call details but not personal info. The incident is linked to a series of data heists targeting Snowflake customers, with stolen data tied to a financial threat actor.
After reviewing the meeting notes, it is clear that AT&T suffered a massive data breach involving almost all its wireless customers’ call and text records. The breach occurred due to illegal downloading of customer data from AT&T’s workspace on a third-party cloud platform. This platform has been linked to a series of data heists from the Snowflake platform, where attackers compromised hundreds of instances. Although AT&T believes the stolen data is not currently public, it has been reported that at least one person has been apprehended in connection with the breach. Additionally, there has been no confirmation that the incident has had a material impact on AT&T’s operations.
