T-Mobile is warning
of a security breach that may have exposed the data of millions of
customers.
The hack, which
occurred Monday, may have compromised information including names, zip
codes, phone numbers, email address, account numbers and account
types, the nation's third-largest wireless provider said in a
statement.
The company's
security team shut down the intrusion, and financial information such
as credit card and Social Security numbers was not exposed.
Affected customers
have either been notified or would be shortly, T-Mobile stated.
A spokesperson
confirmed in an email that the breach affected about 3 percent of
T-Mobile's 77 million customers, or 2 million people.
The security
incident is only the latest at T-Mobile. In May, researchers
detected a
bug in the company's website that allowed anyone to access the
personal data of customers with just a phone number.
The company is
waiting for
regulatory
approval of a proposed $26.5 billion
takeover of Sprint, the fourth-largest carrier in the U.S.
