A RIZAP Employee Uploaded 726 People’s Health Records to a Personal AI Chat
A RIZAP Inc. employee in Japan uploaded health records belonging to 726 people into an unauthorized personal generative AI account while pulling data from the company's health-guidance management system. The incident involved records the company holds on behalf of insurers.
Why this matters: Health data is about as sensitive as it gets. These were not loyalty points or email addresses — they were records people shared with insurers and a fitness company because they had to. The employee did not use an approved tool. They used a personal AI account, which means the company had no visibility and no control over where that data went. This is a gap that exists at most organizations right now. Employees find AI tools useful and reach for them. If companies do not have clear policies and technical guardrails in place, this will keep happening.
