Security News > 2024 > April > AT&T now says data breach impacted 51 million customers

AT&T is notifying 51 million former and current customers, warning them of a data breach that exposed their personal information on a hacking forum.
These notifications are related to the recent leak of a massive amount of AT&T customer data on the Breach hacking forums that was offered for sale for $1 million in 2021.
After BleepingComputer confirmed that the data belonged to AT&T and DirectTV accounts, and TechCrunch reported AT&T passcodes were in the data dump, AT&T finally confirmed that the data belonged to them.
For the admitted security lapse and the massive delay in verifying the data breach claims and informing affected customers accordingly, AT&T is facing multiple class-action lawsuits in the U.S. Considering that the data was stolen in 2021, cybercriminals have had ample opportunity to exploit the dataset and launch targeted attacks against exposed AT&T customers.
AT&T confirms data for 73 million customers leaked on hacker forum.
