Importantly, no phone numbers, account numbers, PINs, passwords, or financial information were compromised in any of these files of customers or prospective customers. 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. Some of the data accessed did include customers’ first and last names, date of birth, SSN, and driver’s license/ID information for a subset of current and former postpay customers and prospective T-Mobile customers. We have no indication that the data contained in the stolen files included any customer financial information, credit card information, debit or other payment information.

While our investigation is still under way and we continue to learn additional details, we have now been able to confirm that the data stolen from our systems did include some personal information. The carrier has now issued a statement giving details of the data obtained in the security breach, which it says is from a mix of past, present, and prospective T-Mobile customers. T-Mobile initially said it couldn’t confirm or deny the privacy fail, but later confirmed that unauthorized access had occurred and that it was investigating what was accessed. The data appears comprehensive: Names, Social security numbers, phone numbers, physical addresses, unique IMEI numbers, and driver’s license information. Motherboard has seen samples of the data, and confirmed they contained accurate information on T-Mobile customers. The forum post itself doesn’t mention T-Mobile, but the seller told Motherboard they have obtained data related to over 100 million people, and that the data came from T-Mobile servers On Monday, a hacker began offering for sale personal data from T-Mobile customers.Ī hacker is selling what they claim is personal data from 100 million T-Mobile customers in the US, stating that this means full records for each customer. T-Mobile also confirmed the claim that the personal data includes both social security numbers and driver’s license details for “a subset’ of people” along with account PINs for some. You could be at risk if you have ever even applied for a T-Mobile account, whether or not it was ever opened… Some of the details differ from claims made by the hacker, but the carrier has admitted that 47.8 million records were taken – and not just from customers. The T-Mobile hack reported earlier this week has now been confirmed by the company.
