Attorney General Knudsen Alerts Consumers Impacted by the Massive 2021
T-Mobile Data Breach to Take Steps to Protect Their Personal
Information

HELENA - After nearly 37,000 Montanans had their personal information
compromised by a massive T-Mobile data breach, Attorney General Austin
Knudsen is urging all Montanans who may have been impacted to take
appropriate steps to protect their information from identity
theft. T-Mobile announced the breach last year but compromised
information has recently been for sale on the dark web. Montanans do
not need to be current customers of T-Mobile to have been affected

On August 17, 2021, T-Mobile reported a massive data breach impacting
53 million current, former, and prospective T-Mobile customers
nationwide. In Montana, that included 2,752 customers and 34,071
former or prospective T-Mobile customers. Among other categories of
impacted information, millions had their names, dates of birth, Social
Security Numbers, and driver's license information compromised.
