The breach, which happened in late February, included usernames, emails, and encrypted passwords. Credit card numbers from paying customers were not accessed.

Under Armor has already been sending emails and in-app messages to its customers who were affected by the breach. The company says it is working with "leading data security firms" to assist in its investigation.

MyFitnessPal users will be required to change their passwords.

Uh, whoever wrote this article needs to quote from the actual MFP/UA release:

"The affected data did not include government-issued identifiers (such as Social Security numbers and driver's license numbers) because we don't collect that information from users. Payment card data was not affected because it is collected and processed separately."

Serious question: Why the F does MyFitnessPal need someone's SSN or Driver's License number? ...Isn't the point to track your food intake and weight?

What are they doing holding customers' social security and driver license numbers?
My thought is that they don't but were just clarifying since this will be national news that nothing of that sort was obtained by hackers.

The British Crown Jewels, the Mona Lisa, and the US Declaration of Independence were also left alone...
