Japanese Railway Operators Hit with Weekend Cyber Attacks
Tokyo Metro, Keio, and Times Car disclosed cyberattacks, including ransomware and a breach of up to 6.6 million people.
Tokyo Metro said an unauthorized party accessed email addresses of 59,000 Metpo loyalty members and has closed the suspected access point. Keio Corporation reported a September 26 ransomware attack that disrupted some group sales systems, including Keio Plaza Hotel, while railway operations continued and no data leak is confirmed. Separately, Times Car said a same-day website intrusion may have exposed personal data on as many as 6.6 million current and former members, including driver's license and identity documents. Passwords were stored in a non-recoverable form, and no link between the incidents is confirmed.
