AT&T is facing multiple class-action lawsuits following the company's admission to a massive data breach that exposed the sensitive data of 73 million current and former customers.
The lawsuit alleges that AT&T failed to adequately protect customers' personal data, leading to a cyberattack and subsequent data breach that exposed sensitive information for 73 million people.
The class action lawsuit concerns a data breach first published in 2021 by threat actor Shiny Hunters, who claimed at the time to have hacked AT&T and attempted to sell the data.
Following an internal investigation, the telecom giant eventually admitted on March 30, 2024, that the exposed data belongs to 7.6 million current AT&T account holders and approximately 65.4 million former account holders.
Dean's complaint asserts that AT&T's inadequate security measures and failure to provide timely, adequate notice about the data breach exposed customers to substantial risks, including identity theft and various forms of fraud.
AT&T confirms data for 73 million customers leaked on hacker forum.
