Mizuno USA Inc, a global sporting goods company, filed an official data breach notification with the State of Indiana on March 11, 2026. The company indicated that the security incident occurred on or about January 31, 2025, and its investigation into the matter remains ongoing as of the filing date.

The public filing states that the breach involved the exposure of several categories of sensitive personal information. The data types reportedly affected include Full Name, Email Address, Mailing Address, Payment Card Information, Social Security Number, Date of Birth, Password or Credential Hash, and Purchase and Order History. The specific combination of exposed data varies for each individual impacted by the incident.

The compromise of such personal information presents various risks to affected individuals. Exposed Payment Card Information could lead to unauthorized transactions, while Social Security Numbers and Dates of Birth are frequently targeted by identity thieves for opening fraudulent accounts or committing tax fraud. Additionally, compromised Password or Credential Hashes could enable unauthorized access to online accounts, and Purchase and Order History might be used in targeted phishing schemes.

Anyone who receives a formal notification from Mizuno USA Inc regarding this data breach should carefully review the document for personalized details about their exposed information. It is generally advisable to remain vigilant by regularly monitoring financial account statements and credit reports for any unauthorized activity. Affected individuals may also consider placing a fraud alert or a security freeze on their credit files with the major credit bureaus to help prevent new accounts from being opened in their name.

It is also important to be cautious of unexpected communications, such as emails or phone calls, that claim to be from Mizuno USA Inc or other entities, as scammers often attempt to exploit data breaches for phishing or other fraudulent activities. Always verify the legitimacy of such communications through official channels before sharing any personal information.

What to do if you were affected

Based on the categories of information reported in this filing, these steps can help limit the risk of identity theft and fraud.

Freeze your credit
Place a free credit freeze with Equifax, Experian, and TransUnion. A freeze blocks new accounts from being opened in your name and can be lifted anytime.
Watch your financial accounts
Review bank and card statements for unfamiliar activity and turn on transaction alerts. Report anything you don't recognize to your bank right away.
Secure your online accounts
Change the password on any account that reused an exposed password and turn on two-factor authentication wherever it's offered.
Stay alert to targeted scams
Be cautious of calls, texts, or emails that reference this breach. Legitimate organizations won't ask you to confirm sensitive details through an unsolicited message.
Keep your notification letter
