T-Mobile says it is investigating a forum post claiming to be selling a mountain of personal data. 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.

The data includes social security numbers, phone numbers, names, physical addresses, unique IMEI numbers, and driver licenses information, the seller said. Motherboard has seen samples of the data, and confirmed they contained accurate information on T-Mobile customers.

"T-Mobile USA. Full customer info," the seller told Motherboard in an online chat. The seller said they compromised multiple servers related to T-Mobile.

On the underground forum the seller is asking for 6 bitcoin, around $270,000, for a subset of the data containing 30 million social security numbers and driver licenses. The seller said they are privately selling the rest of the data at the moment.
