The company said in a statement that it's notifying users of the company's food and nutrition application and website about the hack attack that occurred in late February.
Company officials said the data breach is under investigation.
"The investigation indicates that the affected information included usernames, email addresses, and hashed passwords - the majority with the hashing function called bcrypt used to secure passwords," Under Armour officials said.
The sports retailer said the breach did not include more sensitive information like social security numbers, driver’s license numbers or credit card numbers.
Under Armour officials are urging customers to change their passwords immediately.
