AT&T Resets Passcodes After 73M Accounts Exposed in Data Breach

AT&T has informed millions of customers about a data breach after discovering a dataset containing personal information, including Social Security numbers, for current and former account holders on the "dark web." The company has reset passcodes for current users and is reaching out to affected account holders. It is unclear whether the data originated from AT&T or its vendors, and the compromised information does not appear to include financial data or call history. This comes after a separate wireless network outage in February, which is now under investigation by New York prosecutors.
