GMO Internet Investigates Data Breach Affecting Onamae Cloud Desktop Service
Japanese internet giant GMO Internet is investigating a significant data breach involving its Onamae cloud desktop service, which provides virtualized desktops for financial traders. The company reported that hackers may have published stolen customer and business information following unauthorized access to its systems. Approximately 27,000 servers are suspected to be affected, and the firm has advised customers to reset passwords after reports of unauthorized operations on trading accounts. The breach follows a ransom demand of approximately 8 billion yen (~$50 million) sent to the company in late October. While GMO Internet has not officially linked the incident to the Chinese AI-enabled penetration testing tool 'Artex'—which was recently used in attacks against Japanese and South Korean financial institutions—the timing has raised cybersecurity concerns. The company is currently working with government agencies and collecting devices from customers to assess malware damage.
