(Reuters) -Telecom company AT&T said on Saturday that it is investigating a data set released on the "dark web" about two weeks ago, and said that its preliminary analysis shows it has impacted approximately 7.6 million current account holders and 65.4 million former account holders.

The company said the data set appears to be from 2019 or earlier. AT&T said it does not have evidence of unauthorized access to its systems resulting from the incident.
