AT&T

Telecom giant AT&T disclosed a significant data breach that affected around 110 million customers, involving the exfiltration of call and text messaging records. The breach, taking place between April and October 2022, also exposed cell tower metadata without the content of the communications. Attackers targeted AT&T's Snowflake cloud accounts, leading to the leakage of sensitive call data records, which could be used for intelligence analysis and potentially compromise customer privacy and security.
