BREACHED

15M T-Mobile Customers Exposed in Hack

Two years’ worth of personal data compromised.

T-Mobile said Thursday that hackers have accessed the personal information of 15 million of its customers who applied for the company’s service last month. The breach occurred at Experian, the vendor that processes T-Mobile’s credit applications, and may have affected anyone who sought a regular T-Mobile USA postpaid plan between Sept. 1, 2013, and Sept. 16, T-Mobile CEO John Legere said in an online post. Experian said hackers had breached one of its business units, but emphasized its consumer-credit bureau was not affected. Hackers made off with information including names, addresses, Social Security numbers, birthdays, and even identification numbers from passports and driver’s licenses.
