Japan FSA Minister Reports Unauthorized FX Trading Linked to GMO Internet Server Breach

On October 27, Japan's Minister of Finance and Minister of State for Financial Services Katayama Satsuki briefed reporters on unauthorized FX transactions after customer data on GMO Internet's servers was accessed without permission. Five Japan-registered FX brokers reported customer harm; the FSA urged brokers to alert customers, strengthen monitoring, and reset passwords, while GMO Internet pledged compensation. The minister also said an emergency cybersecurity package would be ready by the end of next week and that G7 agreed in Bangkok to hold a tabletop exercise next year on cross-border cyber incidents involving frontier AI.
