Tracking your fitness goals is good for you. It can be worrying, though, if the information from your fitness tracker is exposed to criminals. That's the state some fitness buffs find themselves in after a breach of 150 million user accounts from the MyFitnessPal app from Under Armour.

The company has said that they have seen no evidence that any accounts have been logged into by an unauthorized user or that any illicit login attempts have been made. In an email to those affected they suggest that all MyFitnessPal users immediately change their passwords, a step that will ultimately be required for all users.

According to a statement from the company, on Feb. 25 Under Armour became aware that someone had gained access to the file in February, with the ability to see usernames, email addresses, and hashed passwords for the users. Under Armour stated that no Social Security numbers were seen because they don't collect them, and no credit card numbers were stolen because that information is stored in a different system.

Under Armour says that they do not know the hacker's identity, though they are continuing to work with law enforcement agencies on the investigation.
