Data of more than 40 million exposed in T-Mobile breach

T-Mobile says about 7.8 million of its current postpaid customer accounts’ information and just over 40 million records of former or prospective customers who had previously applied for credit with the company were involved in a recent data breach

NEW YORK -- The names, Social Security numbers and information from driver's licenses or other identification of just over 40 million former and prospective customers that applied for T-Mobile credit were exposed in a recent data breach, the company said Wednesday. The same data for about 7.8 million current T-Mobile postpaid customers appears to be compromised. No phone numbers, account numbers, PINs, passwords, or financial information from the nearly 50 million records and accounts were compromised, it said. T-Mobile also confirmed that approximately 850,000 active T-Mobile prepaid customer names, phone numbers and account PINs were exposed. The company said that it proactively reset all of the PINs on those accounts. No Metro by T-Mobile, former Sprint prepaid, or Boost customers had their names or PINs exposed. There was also some additional information from inactive prepaid accounts accessed through prepaid billing files. T-Mobile said that no customer financial information, credit card information, debit or other payment information or Social Security numbers were in the inactive file.
