- Experian said a breach may have exposed the data of about 15 million U.S. consumers, CIO reported.
- The breach affected people that applied for T-Mobile services or device financing between Sept. 1, 2013 and Sept. 16, 2015.
- Experian said there is no evidence so far that the data has been used inappropriately.
Experian stored the credit application information to assist T-Mobile with credit decisions and was required to retain it for at least 25 months. T-Mobile said its own consumer credit database was not affected.
The data believed stolen includes names, birth dates, addresses and Social Security numbers.
"Obviously I am incredibly angry about this data breach and we will institute a thorough review of our relationship with Experian," said T-Mobile CEO John Legere.
Experian’s services are sometimes offered free after breaches occur at other companies. But the company has been under fire recently because it has been the victim of several data breaches itself.
