AT&T has finally confirmed that an extensive data breach compromised the information of approximately 73 million current and former customers.

This news comes years after the initial leak in 2021, and after a period when the company denied the breach’s severity.

Based on our preliminary analysis, the data set appears to be from 2019 or earlier, impacting approximately 7.6 million current AT&T account holders and approximately 65.4 million former account holders,” AT&T said in a statement.

The company further says that the security passcodes used to secure accounts were also leaked for 7.6 million customers. 

In 2021, a threat actor known as Shiny Hunters claimed to be selling the stolen data of 73 million AT&T customers. This data includes names, addresses, phone numbers, and, for many customers, social security numbers and birth dates.

At the time, AT&T denied that they suffered a breach or that the data originated from them.
