Declared as the third-largest US wireless carrier suffered a massive data breach attack on August 16th, will now be investigated by the Massachusetts Attorney-general.
Maura Healey announced on Tuesday that she will look into T-hack, Mobile’s which exposed the personal information of over 53 million individuals.
Names, social security numbers, birthdays, driver’s license information, PIN numbers, and other personal information of an estimated 13.1 million current and 40 million past and potential T-Mobile users were exposed in the incident. It was one of a slew of cyberattacks that hit banks, gas pipelines, and hospitals, among other targets, in recent years.
Requests for comment from T-Mobile were unanswered right away. Financial, credit card, or other payment information was not exposed, according to the company.
Healey intends to look into whether the Bellevue, Washington-based firm has enough measures in place to secure the personal information and mobile devices of its customers.
Last month, the US Federal Communications Commission launched an investigation into the matter.
According to court records, consumers and other private plaintiffs have filed at least 23 lawsuits against T-Mobile as a result of the data leak.
