|---|---|
| Breach Date | April 12, 2024 |
| Disclosure Date | July 12, 2024 |
| Records Affected | 73 million |
In 2024, AT&T disclosed two separate data breaches. The first, revealed in March, involved personal data of 73 million current and former customers found on the dark web. The second, disclosed in July, exposed call and text metadata for nearly all AT&T wireless customers over a six-month period in 2022.
What Happened
AT&T confirmed in March 2024 that a dataset containing personal information of approximately 73 million customers had been published on the dark web. The data appeared to originate from 2019 or earlier. Then in July 2024, AT&T disclosed that hackers had accessed call and text records for nearly all wireless customers by exploiting a third-party cloud platform (Snowflake). The stolen metadata covered a period from May to October 2022 and included phone numbers called or texted, call durations, and cell site identification numbers.
What Data Was Exposed
- Full names
- Email addresses
- Mailing addresses
- Phone numbers
- Social Security numbers
- Dates of birth
- AT&T account numbers
- AT&T passcodes
- Call and text metadata (numbers, durations, cell site IDs)
Who Is Affected
The breach affected approximately 73 million current and former AT&T customers for the first incident and nearly all AT&T wireless customers (approximately 110 million) for the call records breach. If you were an AT&T wireless customer between May and October 2022, your call and text metadata was likely exposed.
