In January, T-Mobile said it had a data breach that saw cybercriminals steal about 200,000 call records and other subscriber data. This is by our count the fifth time that T-Mobile was hacked in recent years. The post was deleted in the past few days. The data was allegedly obtained from a T-Mobile-run database server that was connected to the internet, according to a screenshot posted by Bleeping Computer, which also reported that the seller has the IMEI database “going back to 2004.” IMEI and ISMI numbers can be used to uniquely identify and locate a cellphone user.Īn earlier post seen by TechCrunch from the same seller and using the same sample of data claimed to have 124 million records, but still did not name T-Mobile as the source of the data. The forum post, which TechCrunch has seen, asks for 6 bitcoin, or about $275,000, for a 30 million subset of customers’ data. Vice verified a sample of the records from the seller, suggesting the data is in at least partially valid.

The seller told Vice that they had 100 million records on T-Mobile customers, which included customer account names, phone numbers, the IMEI numbers of phones on the account, and Social Security number and driver’s license information - details that the company often collects to verify the identities of its customers. Vice reported this weekend that T-Mobile was investigating a possible intrusion after a seller was claiming to be in possession of millions of records.
