AT&T Inc. has acknowledged a material cybersecurity incident in a recent Form 8-K filing, as confirmed in a letter to the Securities and Exchange Commission (SEC) dated July 31, 2024. The incident involved the exfiltration of nearly all of AT&T's wireless customers' call and text records over a six-month period in 2022. The company has considered both quantitative and qualitative factors, including potential reputational harm and customer relationship impacts, to determine the materiality of the incident. AT&T has stated that as of the filing date, the incident has not had a material impact on its operations or financial results. However, the company is prepared to amend the filing if future risks from the incident lead to a material impact. The U.S. Department of Justice had previously allowed AT&T to delay public disclosure under Item 1.05(c) of Form 8-K. The company's response to the SEC's inquiry clarifies their position on the materiality of the incident and their compliance with disclosure requirements.
