AT&T is facing a $177 million class-action settlement following two alleged data breaches where sensitive customer data was exposed and released on the dark web. The breach involved highly sensitive personal information, including financial details, Social Security numbers, and other critical customer data. The leaked data poses significant risks, such as identity theft, financial fraud, and long-term reputational damage for affected individuals. Customers were advised to change passwords, enable two-factor authentication (2FA), monitor financial transactions, and consider freezing their credit to mitigate potential misuse. The breach underscores the severe consequences of unauthorized access to customer data, particularly when such information is traded or exploited on illicit platforms like the dark web.
