GMO Internet pledges to cover confirmed losses from unauthorized trades after cyberattack

GMO Internet Group CEO Masatoshi Kumagai says unauthorized activity has continued on customer accounts held at more than 70 brokerages and FX firms. He pledges that GMO Internet will cover confirmed losses from unauthorized trades, even if brokers decline refunds. Kumagai acknowledges that internal security warnings weren't addressed quickly or thoroughly enough. He calls for public-private cooperation against cyberattacks and argues that AI misuse is making attacks easier.
