【Actual Record & Caution】Infrastructure Collapse and FX Trading Risks

“Onamae.com VPS” Unauthorized Access Disruption Reveals Fear of Infrastructure Dependency
~When assets are lost for reasons other than market fluctuations, and the self-protection measures traders should take~

“If you manage funds properly and run a proven automated trading (EA) system, you’ll be safe.”

The premise that many traders believed without question was shattered overnight.

Currently, the greatest risk in FX trading is not merely volatility on charts or leverage.

Focusing on the major unauthorized access incident of a large VPS service that occurred on October 21, 2026, this urgent analysis explains the “infrastructure dependency risk” and the structural flaws of the overseas FX environment faced by modern traders.

1. [Actual Record] Overview of the “Onamae.com VPS” Unauthorized Access Incident

On October 20, 2026, many Japanese automated trading (EA) traders who rely on infrastructure such as “Onamae.com Desktop Cloud (FX VPS)” for trading discovered unauthorized programs installed and unauthorized access by a third party.

The operating company (GMO) took the matter seriously and, as an emergency measure to prevent further damage, began a mass shutdown of up to 26,739 VPS servers from 4:00 AM on October 21, resulting in a forced full stop.

“Onamae.com VPS” Unauthorized Access Incident Timeline

October 20, 2026: Unauthorized programs detected on server clusters.
October 21, 04:00: For safety, up to 26,739 VPS servers were urgently forcibly shut down.
Impact: EA running MT4/MT5 stopped entirely. Positions could not be closed.

2. Why Did It Happen? Three Structural Issues This Incident Highlighted

Chaos occurred as infrastructure was cut off in the middle of market movement. The structural challenges revealed are as follows.

① Forced stop of EAs leading to “inability to close positions”

The moment the VPS was forcibly stopped, the EA on MetaTrader (MT4/MT5) halted. In particular, for logics that managed stop-loss and trailing stop only within the program, when the executing component that placed orders vanished, unrealized gains could disappear and unrealized losses could balloon without limit.

② Chain reaction of “forced liquidations” in grid/sincremental martingale-type EAs

A severe consequence is seen in strategies that accumulate positions via averaging down or martingale. When the calculation for closing positions after a rebound no longer runs, positions may be left as the market moves against them, and account funds may be wiped out leading to forced liquidations.

③ Password leakage and risk of secondary damage

Unauthorized access raised concerns that login IDs and passwords for securities accounts or Web wallet authentication information stored on VPS desktops, Notepad, or MT4 could be viewed by third parties. This exposed traders not only to trading losses but to account takeovers.

This incident clearly demonstrates how dangerous a fragile trading style that relies on high leverage + EA automation + single infrastructure dependency can be.

3. The Escalation: Blockage of the “Overseas FX × Domestic Bank Account” Transfer Route

In addition to infrastructure risk, traders using overseas FX (unregistered operators) face a huge barrier: disconnection of withdrawal and remittance infrastructure.

In recent years, under the leadership of the Financial Services Agency and the National Police Agency, domestic banks’ anti-money laundering (AML) monitoring systems have become fully operational. There has been a rapid increase in freezing transfer accounts that go through domestic payment processing companies used by unregistered overseas FX providers.

Concrete impacts of stricter remittance infrastructure

Forced freezing of bank accounts: Frequent transfers and withdrawals to overseas providers lead to sudden freezing of the user’s main domestic bank account.
Tightening as transitional measures for the revised Fund Settlement Act: Withdrawals routed through opaque intermediary companies are gradually being cut off. Even if there are profits, taking them out becomes imminent.
Unsecured risk: Many overseas providers are just under segregated management, and Japanese public authorities cannot intervene if the provider collapses or refuses withdrawals.

4. Solutions: Breaking Free from System Dependency and “Domestic Authorized Environment + High RR Methods”

The fundamental solution to escaping infrastructure failures and withdrawal blockages is a return to a “safe domestic authorized account” and the acquisition of genuine trading analysis skills.

1. The absolute reassurance provided by domestic authorized accounts

FX brokers authorized by the Japanese Financial Services Agency offer legally mandated “completely safeguarded trust” protection. If a broker goes bankrupt, customer funds are 100% protected by a trust bank. Domestic bank account freezing risk is also eliminated.

2. Breaking the grip of low-leverage by adopting “Ultra RR-focused trading”

Moving to a domestic account (maximum leverage 25x) makes high-leverage, high-volume short-term profit methods unusable. Therefore, it is necessary to shift toward increasing the value of each trade (expected value) per trade.

Key to high risk-reward (RR) focused trading:

・Pursue price movement width over win rate: Even with a 40% win rate, if you strictly target a profit of 3 for every 1 loss (RR 1:3), capital will grow steadily.

・Analysis of liquidity: Identify points where orders cluster in advance and hold positions to deep take-profit targets.

・Multifaceted market analysis (correlation analysis + AI assistance): Not only single charts, but also combine dollar index and interest rate trends to identify the onset of large waves.

5. Summary: Self-Protection Checklist Traders Should Implement Now

The trouble at “Onamae.com VPS” is a strong warning to all automated traders and offshore FX traders. To protect your assets, immediately implement the following protective measures.

✅ Immediate asset protection checklist

Check all positions in your account from a mobile app (Ensure you have a manual way to close positions without relying on a VPS).
Change passwords for trading accounts, VPS, and related services (If you reuse passwords, refresh them immediately).
Enable two-factor authentication (2FA) on your My Page and email。
Reassess EA-automated full automation and consider shifting to domestic accounts with “Ultra RR-focused trading”。

Escaping excessive high leverage and system dependency to gain a safe domestic trading environment and lifelong analytical skills is the optimal path for traders to survive in the coming era.
