What Happened in the AT&T Data Breach
AT&T disclosed a data breach in 2024 involving unauthorized access to customer information. The incident affected current, former, and prospective customers.

AT&T stated that the breach was not caused by a system vulnerability but by a third party that obtained credentials from another source.
How Many Customers Were Affected
AT&T initially reported that approximately 73 million current, former, and prospective customers were impacted. The company later confirmed that the data appeared to match information from a 2021 breach. AT&T began notifying affected individuals and offering credit monitoring services. Regulatory authorities in multiple states opened inquiries into the incident.
What AT&T Customers Should Do
