Sportswear giant Under Armour is currently investigating a significant data breach that has reportedly compromised the email addresses and other personal details of millions of its customers. While the company acknowledges the incident, it maintains there is no evidence to suggest that passwords or financial information have been stolen.

The breach is believed to have occurred late last year, affecting an estimated 72 million email addresses, according to information cited by the cybersecurity website Have I Been Pwned. Beyond email addresses, some of the compromised records also included personal information such as names, genders, birthdates and postcodes.

In a statement addressing the claims, the Baltimore-based firm said: "We have no evidence to suggest this issue has affected UA.com or systems used to process payments or store customer passwords. Any implication that sensitive personal information of tens of millions of customers has been compromised is unfounded."
