AT&T Security Breach 2024: AT&T has confirmed a serious data breach, one of the largest in recent history.

The data was illicitly downloaded from Snowflake, a third-party cloud platform. Law enforcement is investigating the breach, with one person under arrest. Even though the compromised data, spanning from May to October 2022, did not contain call or text content or sensitive personal information like social security numbers, it was still enough to determine individuals’ geographical locations.
Another AT&T Breach in January 2023
AT&T also disclosed that a small number of customers’ data was breached on January 2, 2023. The company believes that data is not currently publicly accessible. If someone were to release this information, it could expose the communication records of high-profile individuals, including politicians, executives, activists, and journalists.

Measures Taken After AT&T Security Breach 2024
In response to the breach, AT&T has implemented additional cybersecurity measures, including blocking the point of illicit access. The company has also collaborated with law enforcement and has delayed public notification as deemed appropriate by the Justice Department.

Despite the breach, AT&T insists that operations remain unaffected, even though AT&T’s stock fell 2.7% in pre-market trading on Friday after the breach was confirmed.
