T-Mobile US Inc. has struck long-term partnerships with experts
at cybersecurity firm Mandiant and consulting firm KPMG LLG after
the hack of the wireless company's user database, Chief Executive
Mike Sievert said.
The company has been working with Mandiant for its forensic
investigation since the incident's start. T-Mobile will work with
Mandiant to develop a longer-term plan to mitigate and stabilize
cybersecurity risks across the business, Mr. Sievert said
Friday.
KPMG's cybersecurity team will review T-Mobile's security
policies and performance measurement, Mr. Sievert said.
The breach is the third major customer-data leak that T-Mobile
has disclosed in the past two years. The Bellevue, Wash., company
is the second-largest U.S. mobile carrier with roughly 90 million
cellphones connecting to its networks.
"To say we are disappointed and frustrated that this happened is
an understatement," Mr. Sievert said. He added that the company is
confident that there isn't an ongoing risk to customer data from
the hack.
The company has notified just about every current T-Mobile
customer or primary account holder who had their data compromised,
Mr. Sievert said. Among other measures, the company has offered two
years of free identity protection services with McAfee's ID theft
protection service to all those who might have been affected by the
breach, he said.
The company is actively coordinating with law enforcement on a
criminal investigation, Mr. Sievert said.
John Binns, a 21-year-old American who moved to Turkey a few
years ago, told The Wall Street Journal he was behind the security
breach. He said the company's lax security eased his path into a
cache of records with personal details on more than 50 million
people and counting.
