On Thursday, T-Mobile US CEO, John Legere, said that the names, addresses, Social Security numbers, birthdays, and ID information on more than 15 million customers had been compromised after a breach at Experian.
"The investigation is ongoing, but what we know right now is that the hacker acquired the records of approximately 15 million people, including new applicants requiring a credit check for service or device financing from September 1, 2013 through September 16, 2015," a statement from T-Mobile's head executive added.
In an overview of the event, Experian said that on September 15, they discovered that someone had accessed T-Mobile data housed on one of their servers. The company said the investigation of the incident is ongoing.
Additionally, Experian has determined that their encryption may have been compromised.
"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."
T-Mobile customers are being directed to a website for credit monitoring from Experian, for whatever it's worth.
