On June 10, 2021, Ito Yogoyo reported an incident involving unauthorized access to its servers that exhibited characteristics typical of ransomware attacks. Upon detection, the company promptly shut down the affected systems and networks to prevent further spread.

Following the shutdown, Ito Yogoyo restored its services swiftly and confirmed that no data leakage had occurred as a result of the breach. The incident was reported to the relevant authorities in accordance with Japanese legal and regulatory requirements. In response, the company committed to implementing enhanced security measures to strengthen its defences against similar future threats. To maintain transparency, Ito Yogoyo established a dedicated contact channel for stakeholders seeking information about the breach.
