OANDA Japan required an authenticator for MT5 from 31 October after a hosted desktop intrusion; GMO’s 26,739 figure refers to potentially affected servers, not confirmed compromised brokerage accounts.
A 26 October update moves the incident beyond possible credential exposure. GMO has separately announced compensation for verified trading losses and warned that password changes may leave existing sessions active.
Onamae.com Desktop Cloud identified 26,739 potentially affected server instances. The immediate issue is continuity of terminal-based automation; its published outage-credit scheme also has conditions that matter to customers.
The 20 October announcement links Bitget to a buyer named in GMO’s September filing. The proposed deal offers a locally licensed operating base, with the target’s losses showing the commercial work behind that expansion.
