(Reuters) - Under Armour Inc <UAA.N> <UA.N> said on Thursday that data from some 150 million MyFitnessPal diet and fitness app accounts was compromised in February, in one of the biggest hacks in history, sending shares of the athletic apparel maker down 3 percent in after-hours trade. Data including the usernames, email addresses, and scrambled passwords from approximately 150 million accounts was stolen last month in one of the biggest attacks of its kind. Other information such as social security numbers, driving license numbers, and details from payment cards were thankfully not affected, but email addresses and passwords alone have the potential to cause harm in the wrong hands. “The company will be requiring MyFitnessPal users to change their passwords and is urging users to do so immediately.”

The statement goes on to recommend users be aware of any solicitation for them to provide personal information and to avoid, at all costs, clicking on any links or attachments in suspicious emails.
