Millions of AT&T customers are at risk after a data leak exposed their personal information online.
Some 73 million customers had their personal data posted on the dark web, according to a statement released by AT&T on Saturday.
AT&T revealed that it discovered the data was released two weeks ago, claiming it was unsure whether or not the data came from the company or one of its vendors.
Breached information could have included the account holder’s full name, email and mailing address, phone number, Social Security number, date of birth, and AT&T account number and passcode.
The company has purportedly launched a “robust investigation” involving internal and external cybersecurity professionals. A preliminary analysis found that the data leaked was from 2019 or before.
AT&T’s statement further noted that the company does not have evidence suggesting unauthorized access to its systems.
The company said some 7.6 million current account holders and 65.4 million former account holders were affected.
Those impacted will be sent an email or letter informing them of the breach. They will also be offered complimentary identity theft and credit monitoring services.
AT&T noted that the incident did not affect its operations. It also encouraged both current and former customers with questions to visit their website for more information.
In February, AT&T suffered a nationwide network outage during which tens of thousands of people were suddenly left with no service, as previously reported by The Dallas Express.
“Our initial review of the cause of Thursday’s outage indicates it was due to the application and execution of an incorrect process used while working to expand our network,” John Stankey, AT&T CEO, said in a letter to employees.
The outage affected 74,000 users, and it took AT&T roughly 10 hours to fully restore service. The company then offered a $5 credit to affected users for the trouble.
Dallas reported 19,778 outages, as previously reported by The Dallas Express.
