Under Armour Data Breach: Millions Exposed

Under Armour is currently investigating claims of a significant data breach where customer records were posted on a hacker forum. Millions of users were alerted to potential compromises. Cybersecurity researchers reviewing the leaked data indicate it contains personal details possibly connected to customer purchases.

This exposure is reportedly linked to a ransomware attack in November 2025, for which the Everest ransomware group claimed responsibility. In January 2026, customer data from this incident surfaced publicly. While Under Armour states its investigation is ongoing with external experts, they emphasize there is no evidence that UA.com, payment systems, or stored customer passwords were affected.

Even without sensitive financial information, the compromised data, including names and email addresses, can fuel sophisticated phishing scams. Experts advise customers to check Have I Been Pwned for email exposure, change reused passwords immediately, and enable two-factor authentication on accounts. The company stresses that data security is a top priority.
