Massachusetts Attorney General Maura Healey wrote in a Friday statement that she expects a multi-state probe into the recent data breach at the world’s largest consumer credit monitoring company, Experian Plc. Experian admitted last Thursday that it had experienced a cyberattack that compromised the data of at least 15 million consumers who had sought to open accounts with wireless carrier T-Mobile. A spokesman for the company told reporters that it discovered the breach one of its servers on September 15, and that the stolen data belonged to consumers who had applied for the telecom’s services over the previous two years.
Obviously I am incredibly angry about this data breach and we will institute a thorough review of our relationship with Experian. But right now my top concern and first focus is assisting any and all consumers affected,
said T-Mobile Chief Executive John Legere in a post on the company’s website.
This is the second major theft of consumer data linked to Experian in recent years. The first breach, which took place at a current Experian subsidiary (Court Ventures) prior to its 2012 acquisition, exposed the Social Security numbers of 200 million Americans. Experian declined to comment on Ms. Healey’s statement.
