T-Mobile has confirmed that threat actors hacked their servers in a recent cyber attack but still investigate whether customer data was stolen.
Yesterday, news broke that a threat actor was selling the alleged personal data for 100 million T-Mobile customers after they breached database servers operated by the mobile network.
The hacker told BleepingComputer that the databases stolen during the attack contain the data for approximately 100 million T-Mobile customers, including IMSI numbers, IMEI numbers, phone numbers, customer names, security PINs, Social security numbers, driver's license numbers, and date of birth.
In an email sent to BleepingComputer, T-Mobile has confirmed that some of their servers were hacked in the reported attack and are continuing to investigate if customer data was accessed.
We have determined that unauthorized access to some T-Mobile data occurred, however we have not yet determined that there is any personal customer data involved.
While T-Mobile is continuing its investigation, screenshots of the stolen databases and servers accessed by the attackers indicate that the threat actors downloaded customer data during the cyberattack.
