Nikkei discloses third data breach in a month, 1.8M records exposed
Nikkei Inc. has disclosed a third data breach within roughly a month, with the latest incident exposing approximately 1.83 million personal records. The repeated breaches at the Japanese media and financial information company point to persistent security problems rather than a single isolated incident.
Why this matters: Three breaches in a month is not bad luck. It is a pattern. When a company gets hit repeatedly in a short window, it usually means the underlying problem was not fixed the first time. Nikkei handles financial news and data, so the people in those 1.83 million records are not random. They are likely subscribers, professionals, and businesses who trusted the company with real information. Repeated failures shift this from an incident story to an accountability story.
