Visual Arts Suffers Major Data Breach, Leaking *anemoi* Gold Master and Confidential Data
On June 4, 2026, Visual Arts publisher of the Key brand and titles like Air and Clannad disclosed a significant data breach involving the unauthorized leak of its upcoming game anemoi and potentially sensitive personal and corporate information. The company confirmed that the gold master build of anemoi was illegally uploaded to an overseas website on April 19, just days before its official release on April 24.
Investigations revealed that attackers likely stole authentication credentials for Visual Arts’ cloud storage and internal portal systems, granting access to the game’s build and other confidential data. The breach may have exposed over 10,000 records, including personal information of employees, customers, business partners, and job applicants. While the full scope remains under investigation, the company has not yet confirmed additional leaks or misuse of the compromised data beyond the anemoi build.
In response, Visual Arts filed a report with Japan’s Personal Information Protection Commission on May 11 and is coordinating with relevant authorities. The company has since implemented security measures, including credential revamps, 24-hour monitoring, enhanced threat detection, and employee training. Its official store, VA STORE, has temporarily suspended orders while undergoing maintenance.
The incident follows recent cybersecurity disclosures from other gaming companies, underscoring ongoing risks in the industry. Visual Arts has set up a dedicated contact point for affected individuals, though details on further impacts remain pending.
