Sakura Internet Breach – Hackers Accessed 1.36 million Customers’ Personal Records
Brief
Sakura Internet has disclosed a potential breach involving its sales management system, placing the personal records of up to 1.36 million customer accounts at risk.
The Japanese cloud and hosting provider said the incident was identified during its ongoing investigation into unauthorized access affecting Sakura Rental Server environments.
The company initially announced the rental server intrusion on August 17, 2026. Sakura Internet later confirmed that attackers may also have accessed a separate system used to manage customer contracts and service-related information.
The newly identified access reportedly occurred before August 9, when the company detected the original unauthorized activity involving Sakura Rental Server.
