notifies

AT&T has begun notifying U.S. state authorities and regulators of a security incident after confirming that millions of customer records posted online last month were authentic. According to AT&T the records contained valid data on more than 7.9 million current AT&T customers. AT&T took action some three years after a subset of the leaked data first appeared online, which prevented any meaningful analysis of the data. The full cache of 73 million leaked customer records was dumped online last month, allowing customers to verify that their data was genuine. AT&T eventually acknowledged that the leaked data belongs to its customers, including about 65 million former customers.
