T-Mobile says hackers may have stolen 15 million customers' data
T-Mobile US Inc said personal data of about 15 million of its U.S. subscribers may have been stolen in a breach at a unit of Experian Plc, which processes the telecom carrier's credit applications.
The records include names, dates of birth, addresses and encrypted fields with Social Security number and ID number, as well as additional information used in T-Mobile's own credit assessment.
T-Mobile had 58.9 million customers in total as of June 30. Payment card or banking information were not acquired, T-Mobile Chief Executive John Legere said in a letter on Thursday.
