Some 15 million US customers of mobile network operator T-Mobile could have had their personal data stolen, the company said Thursday, after hackers attacked credit data agency Experian.
The hackers accessed Experian’s records about consumers who applied for T-Mobile USA postpaid services between September 2013 and September 2015, the two firms said.
“These records include information such as name, address and birthdate as well as encrypted fields with Social Security number and ID number (such as driver’s license or passport number),” German-owned T-Mobile said in a statement.
T-Mobile USA chief executive Legere wrote that he was “incredibly angry” about the breach and would review the company’s relationship with Experian.
“We are required to keep records of companies accessing Experian files. This only affected a server housing T-Mobile data,” Experian said on its Twitter feed.
The hack “could lead to an increased risk of identity theft,” Experian said on its website.
