AT&T confirms data for 73 million customers leaked on hacker forum

AT&T confirmed a massive data leak impacting roughly 73 million current and former customers (data appears to date from 2019 or earlier), including names, addresses, phone numbers and, for many, SSNs and birth dates; security passcodes for about 7.6 million accounts were also exposed and have been reset. The dataset matches material previously claimed sold by the threat actor 'ShinyHunters' and was reposted on a hacking forum, prompting notifications and remediation guidance from AT&T.
