GMO investigates possible data leak affecting up to 27,000 servers

GMO Internet is investigating unauthorized access to its Onamae cloud desktop service after suspected attackers posted data allegedly linked to customers and the company. GMO says as many as 27,000 servers may be affected, and customers have reported unauthorized trading-account activity. The company shut down the service, advised password resets, offered compensation and began collecting devices for analysis. The data’s authenticity and the breach’s full scope remain unverified, and GMO has not linked the incident to a separate AI-enabled hacking tool.
