The exposed information varies, but includes customer names, birth dates, contact information, T-Mobile account PINs, account numbers and phone numbers, number of lines, Social Security numbers, IDs, balance, and internal T-Mobile codes used to service customer accounts.
According to the wireless carrier, no personal financial account information or call records were compromised in the incident.
T-Mobile reset the impacted customers’ account PINs and recommends that they update the PINs, either by logging in to T-Mobile.com or by contacting the company’s customer support.
The firm told the Maine Attorney General’s Office that only 836 individuals were impacted by the data breach.
This data breach might have been only a small incident, but it is the second one that T-Mobile has disclosed this year. In January, the company announced that a threat actor abused an API to access the personal information of roughly 37 million postpaid and prepaid customers.
