Under Armour data breach

What happened

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.

What to do if you had an account

1. Turn on two-step sign-in. Enable two-factor authentication where the service offers it, preferably with an authenticator app or a passkey. A leaked password alone is then not enough to get in.
2. Expect targeted phishing. Leaked contact details are used to write convincing fake messages that mention the breached company or your real name. Do not click links in unexpected emails or texts about this account; go to the site by typing its address.
3. Guard against identity fraud. Identity documents and dates of birth cannot be changed like a password. Consider a credit freeze or fraud alert where your country offers one, and be wary of anyone who 'verifies' you using those details.
