"Experian announced Thursday that one of its business units had been hacked," CNBC said. "The breach occurred on a server that contained data on behalf of one of its clients, T-Mobile.
"The data include personal information for a combination of about 15 million customers and credit applicants in the U.S. The data included applicants requiring a credit check for service or device financing from Sept. 1, 2013, through Sept. 16, 2015." Experian said its own consumer credit database was not affected, according to CNBC.
In a letter to consumers, T-Mobile CEO John Legere said:
"Obviously, I am incredibly angry about this data breach and we will institute a thorough review of our relationship with Experian, but right now my top concern and first focus is assisting any and all consumers affected. I take our customer and prospective customer privacy very seriously. This is no small issue for us. I do want to assure our customers that neither T-Mobile's systems nor network were part of this intrusion and this did not involve any payment card numbers or bank account information.
"Experian has assured us that they have taken aggressive steps to improve the protection of their system and of our data.
