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.
"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.
Und0xxed said the hackers found an opening in T-Mobile's wireless data network that allowed access to two of T-Mobile's customer data centers.
The hacker(s) claim the purloined data also includes IMSI and IMEI data for 36 million customers.
In 2015, a computer breach at big three credit bureau Experian exposed the Social Security numbers and other data on 15 million people who applied for financing from T-Mobile.
