[AvaTrade](https://akta.pro/company-profiles/0005w8k/avatrade) Japan confirmed that hackers accessed customer accounts and executed unauthorized trades through external services, including virtual private server providers. The broker did not disclose the number of compromised accounts, the value of unauthorized transactions or any confirmed customer losses, [FinanceFeeds](https://financefeeds.com/exclusive-avatrade-japan-says-hackers-accessed-accounts-and-executed-unauthorized-trades/) reported on October 23, 2026.

## What AvaTrade Japan Confirmed About the Breach

AvaTrade's notice identifies three unauthorized activities: third-party access, account logins and trading transactions. The broker said it found no evidence that customer credentials or personal information had leaked from its own systems. It instructed customers to change passwords for its account-management portal and MetaTrader 4 and MetaTrader 5 platforms immediately, and to inspect login records, transaction histories and notifications about unfamiliar devices. Customers using external VPS providers were told to review security warnings from those services, and anyone spotting suspicious trading activity was told to contact AvaTrade support.

AvaTrade had issued an earlier warning on October 9 about increasing attempts to access brokerage accounts using credentials exposed through external services. That notice warned about unauthorized login attempts but did not establish that trades had been executed.

The confirmation follows a cyberattack against Japanese hosting provider [GMO Internet, Inc.](https://akta.pro/company-profiles/004npdv/gmo-internet-inc), which said up to 26,739 servers could have been affected. GMO began investigating on October 19 after a customer inquiry and confirmed malicious software installations in some customer server environments the following day. It began suspending servers across all service plans on October 21 and consulted police on October 22. AvaTrade did not explicitly attribute its confirmed unauthorized transactions to GMO's infrastructure, and GMO's figure represents potentially affected server environments, not confirmed brokerage accounts.
