Under Armour says the data of about 150 million people was taken from its MyFitnessPal app and web site. MyFitnessPal is a popular tool for managing diet and exercise. The company says it noticed unauthorized access to its servers by a third party on March 25 and immediately took steps to investigate the issue. Under Armour believes the hackers made off with usernames, email addresses, and hashed passwords. Data such as social security numbers, driver's license numbers, and payment card data was not accessed. Under Armour began notifying impacted users within several days of the breach. The notice provides users with recommendation on steps they can take to protect their information. Under Armour is encouraging all users to change their passwords immediately. The investigation into the nature of the breach is ongoing and Under Armour will provide more information as it is available. Customers can find more information on a FAQ posted to the company's web site. In 2016, Under Armour partnered with HTC to create a fitness-focused Health Box, which included a smart scale that could talk to apps on HTC phones.
