Approximately eleven million subscribers were affected by the breach.
AT&T suffered a data breach affecting nearly all of its customers' call and text records between May 1, 2022, and October 31, 2022.

The stolen data includes call and text records of customers interacting with other wireless networks.
In a significant data breach, hackers gained unlawful access to call and text records of nearly all AT&T customers between May 1, 2022 and October 31, 2022. The stolen data includes records of calls and texts made between these customers and other wireless networks. Approximately eleven million wireless subscribers were affected by this breach.
The compromised data does not contain the contents of the calls or texts nor their time or date. However, cybercriminals may use this information to infer sensitive details about individuals' lives and potentially locate them based on call durations and cell site identification numbers.
AT&T launched an investigation after discovering the breach on April 19, 2024. The company has engaged leading cybersecurity experts to understand the nature and scope of the criminal activity. One person has been arrested in connection to the incident, and AT&T is continuing to work with law enforcement agencies such as the Federal Communications Commission (FCC), FBI, and US Department of Justice to apprehend others involved.
This breach marks another setback for AT&T following a data breach in March 2024 that exposed 73 million current and former accounts on the dark web. The company also experienced back-to-back service issues, including a broad network outage in February and another incident in June.

The authors use the term 'nearly all' AT&T cellphone customers and 'many non-AT&T customers' which is a Dichotomous Depiction. They also use the phrase 'very small number' of customers from January 2, 2023, which is an imprecise statement that could be considered an Appeal to Authority if taken out of context.

The article contains editorializing and sensationalism. The author quotes Rachel Tobac and Runa Sandvik making assertions about the potential harm of the stolen metadata, implying that it could reveal sensitive information about individuals' lives. However, there is no clear evidence provided in the article that this is a certainty, only speculation.

The article by Lorenzo Franceschi-Bicchierai on TechCrunch discusses the AT&T phone records data breach and its implications. The author provides a clear and informative overview of the breach, its extent, and potential risks for affected customers. However, there are a few instances of logical fallacies present in the article.
For some of the affected customers, the cybercriminals were also able to steal cell site identification numbers linked to phone calls and text messages, according to AT&T. This means that — potentially — someone could use this information to figure out the approximate location of a customer when they made a certain call or sent a text, and perhaps infer sensitive information about their lives.
