Data Breach Affects 73 Million Current and Former AT&T Customers

AT&T has confirmed a large data breach of its customer data. The data includes full name, email address, mailing address, phone number, social security number, date of birth, AT&T account number, and passcode (4-digit PIN). AT&T has proactively reset the passcodes of affected customers, and sent out notifications via email and/or letter. The data includes 7.6 million current AT&T account holders and 65.4 million former account holders. The data appeared on the dark web recently, but seems to have been collected in 2019. The data does not contain personal financial information or call history.
