AT&T says that they did not suffer a data breach after a well-known threat actor claimed to be selling a database containing the personal information of 70 million customers.
The hacker states that they are willing to sell it immediately for $1 million.
This authentication is then used to steal databases, which they then sell directly to other threat actors or utilize a middle-man data breach seller.
ShinyHunters has told BleepingComputer that they are not surprised that AT&T denies the breach and continues to state that it comes from them.
This news comes soon after a different threat actor tried to sell the stolen data of 100 million T-Mobile customers.
T-Mobile latest confirmed they were hacked, and the cyberattack exposed the personal data of 48 million T-Mobile customers.
