AT&T is investigating how tens of millions of former and current customers had their personal information leaked on the dark webearlier this month.
In addition to the 7.6 million current AT&T customers affected, the telecom giant said in an announcement Saturday about 65.4 million former customers “had some data released” within the data set, which “appears to be from 2019 or earlier.”
Leaked onto the dark web two weeks ago, the data set had personal information including Social Security numbers and data from “AT&T data-specific fields.” The “compromised data” does not contain personal financial information or call history, AT&T said.
The company is investigating the incident, but said “it is not yet known whether the data in those fields originated from AT&T or one of its vendors.”
The company will contact all current and past customers whose “sensitive personal information” was compromised and has launched “a robust investigation supported by internal and external cybersecurity experts.
