Mizuno Data Breach Settlement: How to File Your Claim for Up to $5,000

Mizuno USA has agreed to a class action settlement after a 2024 data breach exposed the personal information of approximately 1,200 people.

The breach was discovered on November 6, 2024, but investigators found that hackers had been inside Mizuno's network since August 21, copying files periodically through October 29, 2024. The compromised data includes names, Social Security numbers, financial account numbers, driver's license numbers, and passport numbers. The BianLian ransomware group claimed responsibility for the attack.

Mizuno USA is the American subsidiary of Mizuno Corporation, a Japanese sporting goods company known for making equipment and apparel for baseball, golf, running, volleyball, and other sports.

The lawsuit alleged that Mizuno failed to implement reasonable cybersecurity measures to protect the sensitive information it was storing. Mizuno has not admitted wrongdoing but agreed to settle the case.

Who's Eligible

You're eligible if you received a data breach notification letter from Mizuno USA informing you that your information was potentially compromised in the November 2024 breach.

What You Could Get

If you file a claim, you have a few options. You can receive up to $475 in reimbursement for ordinary losses related to the breach — things like bank fees, phone charges, postage, and up to four hours of lost time at $15 per hour. If you experienced identity theft or fraud as a result of the breach, you can claim up to $5,000 in extraordinary losses. If you don't have documented losses, you can choose a $50 alternative cash payment instead. All class members are also eligible for 24 months of credit monitoring with at least $1 million in fraud protection.
