The 2024 AT&T Data Breach — 73 Million Customers Affected
In March 2024, AT&T disclosed that a massive dataset containing personal information of approximately 73 million current and former customers had been leaked onto a dark web forum. The exposed data — which AT&T confirmed came from a 2019 breach that was concealed for years — included full names, home addresses, phone numbers, dates of birth, AT&T account numbers, and Social Security numbers. The disclosure triggered multiple class action lawsuits alleging AT&T failed to adequately protect customer data and delayed notification for years. If you were an AT&T customer at any time between 2019 and 2024, your personal information was very likely exposed. Class action settlements arising from this breach are expected to be among the largest telecom settlements in history.
