04:17 AM EDT, 04/01/2024 (MT Newswires) -- AT&T ( T ) said Saturday information from about 7.6 million current customers and about 65.4 million former account holders was included in a data set released to the "dark web" two weeks ago.

The leaked data appears to be from 2019 or earlier, the company said.

The wireless carrier said it does not yet know where the data originated and it does not have evidence of a breach in its systems, but it has launched an investigation supported by cybersecurity experts.

The company said the incident has not had any material impact on its operations.
