Under Armour: a data breach

In November 2025, the Everest ransomware group claimed Under Armour as a victim and attempted to extort a ransom , alleging they had obtained access to 343GB of data. In January 2026, customer data from the incident was published publicly on a popular hacking forum , including 72M email addresses. Many records also contained additional personal information such as names, dates of birth, genders, geographic locations and purchase information.
