Hundreds of thousands of current and former AT&T customers’ leaked data, including Social Security numbers, were posted on the dark web earlier this month.
The leak prompted a “robust investigation supported by internal and external cybersecurity experts,” the telecommunications giant said Saturday.
The compromised data appears to be from 2019 or earlier and included the knowledge of roughly 7.6 million current customers and 65.4 million former ones, AT&T said.

The leaked information can have included customers’ names, email and mailing addresses, phone numbers, Social Security number, dates of birth, AT&T account numbers and passcodes.
“It isn’t yet known whether the information in those fields originated from AT&T or one among its vendors,” the corporate said, adding that there isn’t any evidence up to now that the leak was attributable to unauthorized access to the corporate’s systems.
AT&T reset affected customers’ passwords after TechCrunch alerted the corporate Monday that an enormous trove of knowledge containing customers’ passwords had been dumped on the dark web, the outlet reported.
The corporate said it’s reaching out to those affected by the breach to allow them to know what information was leaked and is offering free identity theft and crediting monitoring services.
The leak got here a month after hundreds of thousands of AT&T customers experienced a nationwide cellphone outage that left some without service for as much as 12 hours. The corporate blamed the disruption on a software update gone awry.
