T-Mobile says hackers stole personal data from millions of customers

T-Mobile said Wednesday that hackers stole personal information linked to 40 million former and prospective customers that applied for credit from the telecommunications company, with the data including Social Security and driver's license records in some cases.

The cyberattack also compromised personal data for 7.8 million current T-Mobile postpaid customers. No phone numbers, account numbers, PINs, passwords, or financial information from the nearly 50 million records and accounts were compromised, according to T-Mobile. But about 850,000 active T-Mobile prepaid accounts had their phone numbers and account PINs exposed. The company said it has reset all of the PINs on those accounts, and will be notifying those customers immediately.
