Nihon Kotsu, one of Japan's largest taxi operators, said unauthorized access to its systems in July may have leaked personal information on about 290,000 people, NHK reported. Those affected include people in accidents involving its drivers, users of its hire-car service and applicants in its hiring process.
The company disclosed the breach on Friday, roughly three months after the July intrusion. The source does not say why the disclosure came in October, or when in July the access occurred.
Nihon Kotsu has not said what kind of data was exposed for each group, or whether the information has been misused. The company's statement, as carried by NHK, gives the total number of people affected as approximately 290,000.
The disclosure came the same day that other unauthorized-access cases were reported in Japan, including a possible breach at the crypto exchange Binance with an estimated impact of about 990 billion yen. Separately, a victim of a fraud case involving GMO, with losses of 40 million yen, told NHK: "I am fighting fear the whole time."
