The content of the calls and messages was not compromised and customers’ personal information was not accessed — but the records did include phone numbers. The sheer size of the hack underlines the scale of the cybersecurity challenge facing big business.
AT&T’s wireless network has 127 million devices connected to it, according to the company’s 2023 annual report.
“While the data does not include customer names, there are often ways, using publicly available online tools, to find the name associated with a specific telephone number,” the company said in its SEC filing.
AT&T said it has “taken additional cybersecurity measures in response to this incident including closing off the point of unlawful access.” Customers affected by the hack will be contacted, it said.
The company said in its SEC filing that the U.S. Department of Justice ruled twice that it should publicly announce details of the hack, on May 9 and June 5, according to SEC rules.
AT&T added that it is assisting law enforcement officers in efforts to arrest the hackers.
“Based on information available to AT&T, it understands that at least one person has been apprehended,” the company said, without providing further details.
The company sought to assure customers that, at least as of Friday, “AT&T does not believe that the data is publicly available.”
The filing also said the hack would not impact its operations or negatively affect its financial results.
