AT&T confirms arrest in data breach of more than 110 million customers

AT&T confirmed that a significant data breach affected about 110 million customers, revealing call data, but not particular call details or personal information. The breach stemmed from a series of Snowflake attacks on a third-party workspace. However, AT&T does not believe the stolen data is publicly available or that it will have a substantial impact on its operations or financial condition. It was the first company allowed by the FBI and the Department of Justice to temporarily keep the details of the breach confidential.
