T-Mobile’s credit application processor Experian was hacked, potentially exposing the highly personal information of more than 15 million people in the United States. The stolen information includes names, addresses, phone numbers and most unfortunately Social Security numbers. Hackers have their hands on two years worth of sensitive identifying information that T-mobile uses to check credit ratings, which could possibly make the rounds on the black market. The telecommunication giant said that no credit or debit card numbers of its customers were stolen in the breach.
