AT&T announced Saturday that it’s investigating an incident two weeks ago that led to tens of millions of consumers’ data being published on the dark web, a portion of the Web that may only be accessed using special software.
The corporate has reset the passcodes of the 7.6 million current users who were impacted and said it’s actively contacting those customers, together with the 65.4 million former account holders who also had their data compromised.
“As of today, this incident has not had a cloth impact on AT&T’s operations,” the corporate wrote in a press release on Saturday.
AT&T’s preliminary review found that the leaked data was from roughly 2019 or earlier and included personal information equivalent to names, home addresses, phone numbers, dates of birth, and Social Security numbers. The information set doesn’t contain personal financial information or call history.
AT&T has encouraged users, who will receive an email in the event that they were affected, to establish fraud alert accounts and monitor their account activity and credit reports. The corporate has not yet identified the source of the leak.
In February, AT&T customers experienced an hours-long cellular outage, which the corporate clarified resulted from a system issue, not a cyberattack. The corporate’s CEO, John Stankey, later apologized for that incident and provided customer credits to those impacted.
CLARIFICATION: AT&T said it’s investigating an incident two weeks ago that led to tens of millions of consumers’ data being published on the dark web. It’s unclear whether there was a breach of the system.
