- T-Mobile confirms cyberattack compromising personal data of 48 million customers
On August 15, a hacker claimed to have breached T-Mobile and stolen 106 GB of data containing the names, addresses, account login credentials, and social security numbers (SSN) belonging to 100 million customers. A sample dataset of 30 million driver’s licence numbers and SSNs were uploaded on the dark web and put on sale at a price of 6 Bitcoins, or roughly $270,000.
Despite initially denying the claim, T-Mobile admitted on August 18 that the hacker gained access to its servers and obtained the personal information of 7.8 million postpaid customers and 40 million former and prospective customers who had previously registered for postpaid services with the company.
Additionally, T-Mobile said that 850,000 current prepaid customers had their phone numbers and login credentials stolen. The PIN numbers of these customers were reset immediately.
T-Mobile is currently in the process of contacting all victims and promises to provide two years of free identity protection service. The hacker did not demand any ransom from T-Mobile as they claim to have found buyers online.
