Mizuno USA Inc data breach

Clerk's notes

Mizuno USA Inc, a global sporting goods company, has formally reported a data security incident to the Indiana Attorney General, with the filing dated March 11, 2026. This breach occurred on January 31, 2025, and is currently under a 'monitoring' investigation status. The incident has raised concerns regarding the adequacy of the company's digital safeguards for its extensive data holdings.

The reported data exposure includes a broad range of sensitive information: Full Name, Email Address, Mailing Address, Payment Card Information, Social Security Number, Date of Birth, Password or Credential Hash, and Purchase and Order History. These categories encompass both customer transaction details and internal personnel records, highlighting the extensive nature of the data potentially compromised.

Individuals whose data was affected face significant risks. The exposure of Payment Card Information, Full Name, and Mailing Address could facilitate unauthorized charges and fraudulent purchases. Meanwhile, compromised Social Security Numbers, Dates of Birth, and Password or Credential Hashes could lead to severe identity theft, unauthorized account access, and the opening of fraudulent credit lines in a victim's name.

As an entity handling substantial volumes of personal data, Mizuno USA Inc was bound by legal obligations to implement robust security measures to protect this information. The occurrence of a data breach of this scale suggests that the company's digital defenses may have fallen short of industry standards and regulatory expectations under applicable data protection frameworks.
