AT&T Data Breach Exposes Millions of Customers' Personal Information

AT&T recently discovered a data breach exposing 7.6M current and 65.4M former customers' personal information like SSNs and passcodes. It's unknown if the data came from AT&T or a vendor.

Breached customer data varies but may include names, emails, addresses, phone numbers, DOBs, account numbers, SSNs, and passcodes. Financial info and call history seem unaffected.

Impacted customers will receive emails or letters from AT&T about the breach. Passcodes for current customers have already been reset.

This closely resembles an unacknowledged 2021 AT&T breach. Lawsuits may follow if AT&T incorrectly assessed that one.

Consumers can better protect themselves going forward by using strong passwords, enabling multifactor authentication, monitoring accounts, and consider credit freezes.
