US brand Under Armour revealed that the popular health and nutrition tracking app MyFitnessPal has suffered a data breach last month, after being hacked. Personal details of around 150 million app users, including passwords, usernames and email addresses are at risk. Payment cards were not affected.
In a statement, Under Armour revealed that although the attack occurred in late February, they did not discover the security breach until 25th March. Users were alerted via email four days later, and have been urged to change their passwords immediately, including those for other accounts connected to MyFitnessPal.
Under Armour said: “The company quickly took steps to determine the nature and scope of the issue and to alert the MyFitnessPal community of the incident. The affected data did not include government-issued identifiers (such as Social Security numbers and driver’s licence numbers), which the company does not collect from users.
“Payment card data was also not affected because it is collected and processed separately.”
The MyFitnessPal app allows users to track their calorie intake and calories burned during exercise. The popular app was bought by Under Armour in 2015.
As yet, the identity of the hackers is not known. Under Armour is working with the police and data security firms to investigate the breach.
According to the tech blog Engadget, the hack did not affect Under Armour’s other fitness apps, including MapMyRun and MapMyWalk.
