AT&T Data Breach Exposes Nearly All Customer Information

In a shocking revelation, telecommunications giant AT&T disclosed on Friday that the data of nearly all its customers was downloaded to a third-party platform in a security breach that occurred in 2022. This breach impacted not only AT&T’s cellular customers but also 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 assured customers that the compromised data does not include the content of calls or texts, Social Security numbers, dates of birth, or other personally identifiable information. However, files containing AT&T records of calls and texts between May 1, 2022, and Oct. 31, 2022, were among the compromised data.

The company, which has over 100 million customers in the U.S. and almost 2.5 million business accounts, has launched an investigation and is working with cybersecurity experts to understand the nature and scope of the breach. AT&T also confirmed that a very small number of customers had records compromised from Jan. 2, 2023.

This breach is just one in a series of cyberattacks targeting businesses, schools, and health systems globally. Earlier this year, AT&T reported another breach that exposed sensitive information of millions of current and former account holders. The company is not alone in facing cybersecurity challenges, as other industries like auto dealerships and education systems have also fallen victim to cyberattacks.
