Communications giant T-Mobile said today it is investigating the extent of a breach that hackers claim has exposed sensitive personal data on 100 million T-Mobile USA customers, in many cases including the name, Social Security number, address, date of birth, phone number, security PINs and details that uniquely identify each customer’s mobile device.
On Sunday, Vice.com broke the news that someone was selling data on 100 million people, and that the data came from T-Mobile. In a statement published on its website today, the company confirmed it had suffered an intrusion involving “some T-Mobile data,” but said it was too soon in its investigation to know what was stolen and how many customers might be affected.
“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,” T-Mobile wrote.
“We are confident that the entry point used to gain access has been closed, and we are continuing our deep technical review of the situation across our systems to identify the nature of any data that was illegally accessed,” the statement continued. “This investigation will take some time but we are working with the highest degree of urgency. Until we have completed this assessment we cannot confirm the reported number of records affected or the validity of statements made by others.”
The intrusion came to light on Twitter when the account @und0xxed started tweeting the details. Reached via direct message, Und0xxed said they were not involved in stealing the databases but was instead in charge of finding buyers for the stolen T-Mobile customer data.

They claim one of those databases holds the name, date of birth, SSN, drivers license information, plaintext security PIN, address and phone number of 36 million T-Mobile customers in the United States…
