DALLAS, March 30,
2024 /PRNewswire/ -- AT&T* has determined that
AT&T data-specific fields were contained in a data set released
on the dark web approximately two weeks ago. While AT&T has
made this determination, it is not yet known whether the data in
those fields originated from AT&T or one of its vendors. With
respect to the balance of the data set, which includes personal
information such as social security numbers, the source of the data
is still being assessed.
AT&T has launched a robust
investigation supported by internal and external cybersecurity
experts. Based on our preliminary analysis, the data set
appears to be from 2019 or earlier, impacting approximately 7.6
million current AT&T account holders and approximately 65.4
million former account holders.
Currently, AT&T does not have evidence of unauthorized
access to its systems resulting in exfiltration of the data set.
The company is communicating proactively with those impacted and
will be offering credit monitoring at our expense where applicable.
We encourage current and former customers with questions to
visit www.att.com/accountsafety for more information.
As of today, this incident has not had a material impact on
AT&T's operations.
