Under Armour is investigating a data breach that compromised 72 million customer email addresses, along with names, genders, birthdates, and ZIP codes. The breach reportedly occurred late last year, according to cybersecurity site Have I Been Pwned.

The Baltimore-based clothing retailer says there's no evidence hackers accessed passwords or financial information from UA.com or payment systems. Have I Been Pwned CEO Troy Hunt agrees with Under Armour's assessment but expressed surprise at the company's lack of an official disclosure statement given the breach's scale and timing.
