"Our preliminary analysis is that approximately 7.8 million current T-Mobile postpaid customer accounts’ information appears to be contained in the stolen files, as well as just over 40 million records of former or prospective customers who had previously applied for credit with T-Mobile." the company said in a statement on Wednesday. "Importantly, no phone numbers, account numbers, PINs, passwords, or financial information were compromised in any of these files of customers or prospective customers.
This past weekend, Motherboard first reported that it was in contact with the hackers, who claimed to have access to the data of millions of T-Mobile users.
This is not the first time that T-Mobile is facing a potential data breach. The mobile carrier, which has over 104.8 million customers, has been targeted a few times over the past couple of years.
In December 2020, the company revealed that about 200,000 of its customers’ information was illegally accessed.
In 2019, another security breach impacted a “small number" of its prepaid customers. Similarly, hackers were able to obtain information from around two million customers was in 2018.
