Some of the data exposed by MajorNelson, including birthdates, Social Security numbers, addresses, and phone numbers, have already been verified by BleepingComputer. Separate confirmations of the veracity of some of the data have also been made by VX-Underground and Dark Web Informer.

AT&T has a history of malware and data breaches. Roughly a year ago, the company warned millions of its users that some of their sensitive data was exposed in a supply chain cyberattack. Apparently, a marketing vendor was breached a few months earlier, resulting in the theft of AT&T’s data.
