Under Armour data breach — are you affected?

In November 2025 a ransomware group claimed it had stolen 343 GB from Under Armour, and in January 2026 customer data was published on a hacking forum. It includes about 72 million email addresses, and many records add names, birth dates, genders, locations and purchase history. No passwords are listed, but the profile data is well suited to targeted phishing.

What this means for you

Based on the types of data in this breach, in order of importance.

  • Stay alert to identity fraud

    Birth dates and identity document numbers cannot be changed like a password. Be wary of anyone who quotes them to sound legitimate, check bank statements and credit reports regularly, and use a credit-file freeze or fraud alert where your country offers one.

  • Expect more targeted phishing

    Your email address ties you to this service, which is enough for a believable message such as a fake account warning. Check the sender and the web address before you sign in, and go to the site directly instead of using links in email.

  • Limit what attackers can personalise

    Names, employers, job titles and social profiles make impersonation and spear-phishing easier. Check what your public profiles reveal, and be careful with unexpected requests that use your real name or workplace.
