Under Armour is investigating a data breach that occurred late last year, affecting 72 million customer email addresses according to cybersecurity site Have I Been Pwned. The stolen data included emails, names, genders, birthdates, and ZIP codes, but no passwords or financial information appears compromised.

The Baltimore-based clothing retailer maintains that their main website and payment systems weren't affected. Cybersecurity expert Troy Hunt agrees with Under Armour's assessment but expressed surprise at the company's lack of official disclosure given the breach's scale and timing. Under Armour called any claims about sensitive personal information being compromised "unfounded."
