AT&T Data Breach Exposes Call Logs of 109 Million Customers In April 2024, AT&T experienced a significant data breach that compromised the call logs of 109 million customers. The breach revealed sensitive information such as phone numbers, call durations, and location data from records dating back to May 2022. Although AT&T stated that the logs did not include call content or personal identifiers like Social Security numbers, the metadata can still reveal intimate details about users' lives. The breach was part of a larger trend of telecom data being targeted, with AT&T being one of several companies affected by credential-based thefts. The long retention period for call logs, often up to five years, increases the risk of exposure. This incident raises concerns about how telecommunications companies handle and protect customer data. The breach has not been linked to any specific attack vector or tool in the articles. 2 sources 49
