United States. Communications giant T-Mobile confirmed it is conducting an investigation into a breach that hackers say has exposed sensitive personal data of the company's 100 million customers in the United States.
"We have been working 24 hours a day to investigate allegations that T-Mobile's data may have been illegally accessed. We take the protection of our customers very seriously and are conducting a thorough analysis together with digital forensic experts to understand the validity of these claims, and we are coordinating with law enforcement."
The company confirmed that "unauthorized access to some T-Mobile data," but does not yet determine that there is any personal data of the customer involved.
"We are confident that the entry point used to gain access has been closed and we continue our in-depth technical review of the situation across all of our systems to identify the nature of the data that was illegally accessed. This research 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 affected records or the validity of statements made by others."
On Sunday, Vice.com broke the news that someone was selling data on 100 million people and that the data came from T-Mobile. "We understand that customers will have questions and concerns, and resolving them is vitally important to us. Once we have a more complete and verified understanding of what happened, we will proactively communicate with our customers and other stakeholders."
Analysis indicates that the accounts were being offered through twitter, with the publication and offer of those who appear to be experts in data theft and marketing. In 2015, a computer breach at Experian's big three credit bureaus exposed the Social Security numbers and other data of 15 million people who applied for T-Mobile financing.
