Telecommunications giant AT&T reports that data of nearly all customers was downloaded to a third-party platform in a security breach. The breach took place largely over five months in 2022. It hit customers of AT&T’s mobile customers, customers of mobile virtual network operators using AT&T’s wireless network, as well as its landline customers who interacted with those cellular numbers. AT&T says the data does not contain the content of calls or texts, personal information such as Social Security numbers, dates of birth, or other personally identifiable information. AT&T, however, said that there are often ways using publicly available online tools to find the name associated with a specific telephone number.
