The Massachusetts’ attorney general said she will investigate the cyberattack against T-Mobile that exposed personal information of more than 53 million people.
The U.S. wireless carrier disclosed the breach on August 16. The carrier said the breach exposed names, birthdays, social security numbers, driver’s license information, PIN numbers and other data belonging to an estimated 13.1 million current and 40 million former and prospective T-Mobile customers.
It was one of many cyberattacks in recent years across several industries, affecting banks, gas pipelines and hospitals, among other operations, according to Reuters.
T-Mobile did not immediately respond to Reuters’ requests for comment. It has said the breach did not expose financial, credit card or other payment information.
Massachusetts’ Attorney General Maura Healey plans to investigate whether the Bellevue, Washington-based company had proper safeguards to protect customers’ personal information and mobile devices. The FCC opened a related probe last month, Inside Towers reported.
According to court records, Consumers and other private plaintiffs have filed at least 23 lawsuits against T-Mobile over the breach.
