"text": "On April 19, 2024, AT\u0026T Inc. (“AT\u0026T”) learned that a threat actor claimed to have unlawfully accessed and copied AT\u0026T call logs. AT\u0026T immediately activated its incident response process to investigate and retained external cybersecurity experts to assist. Based on its investigation, AT\u0026T believes that threat actors unlawfully accessed an AT\u0026T workspace on a third-party cloud platform and, between April 14 and April 25, 2024, exfiltrated files containing AT\u0026T records of customer call and text interactions that occurred between approximately May 1 and October 31, 2022, as well as on January 2, 2023, as described below.\nThe data does not contain the content of calls or texts, personal information such as Social Security numbers, dates of birth, or other personally identifiable information. Current analysis indicates that the data includes, for these periods of time, records of calls and texts of nearly all of AT\u0026T’s wireless customers and customers of mobile virtual network operators (“MVNO”) using AT\u0026T’s wireless network. These records identify the telephone numbers with which an AT\u0026T or MVNO wireless number interacted during these periods, including telephone numbers of AT\u0026T wireline customers and customers of other carriers, counts of those interactions, and aggregate call duration for a day or month. For a subset of records, one or more cell site identification number(s) are also included. 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.\nAT\u0026T has taken additional cybersecurity measures in response to this incident including closing off the point of unlawful access. AT\u0026T will provide notice to its current and former impacted customers.\nOn May 9, 2024, and again on June 5, 2024, the U.S. Department of Justice determined that, under Item 1.05(c) of Form 8-K, a delay in providing public disclosure was warranted. AT\u0026T is now timely filing this report. AT\u0026T is working with law enforcement in its efforts to arrest those involved in the incident. Based on information available to AT\u0026T, it understands that at least one person has been apprehended. As of the date of this filing, AT\u0026T does not believe that the data is publicly available.\nAs of the date of this filing, this incident has not had a material impact on AT\u0026T’s operations, and AT\u0026T does not believe that this incident is reasonably likely to materially impact AT\u0026T’s financial condition or results of operations.\nCautionary Language Concerning Forward-Looking Statements\nInformation set forth herein contains financial estimates and other forward-looking statements that are subject to risks and uncertainties, and actual results might differ materially. A discussion of factors that may affect future results is contained in AT\u0026T’s filings with the Securities and Exchange Commission. AT\u0026T disclaims any obligation to update and revise statements contained herein based on new information or otherwise, except as required by law."
