CFDs are complex financial instruments and carry a high level of risk due to leverage. A significant proportion of retail investors incur losses when trading leveraged products such as CFDs. You should carefully consider whether you understand how CFDs work and whether you can afford to take the high risk of losing your capital.
A DDoS attack (Distributed Denial of Service) is an attempt to overload a server or network with massive traffic until it becomes inoperable. Thousands of infected devices (a botnet) send simultaneous requests to the target system. The server cannot handle so many requests at once and stops functioning for legitimate users.
The attacker doesn’t need to gain access to the system to cause damage. They just need to saturate it. Imagine a store with the capacity to serve 100 customers. If 10,000 people walk in at the same time with no intention of buying anything, the actual customers can’t even get in. That’s what happens in the digital world.
The devices carrying out the attack are usually ordinary users’ computers infected with malware without their knowledge. The attacker controls them remotely and activates them all simultaneously against the target.
Trading platforms, cryptocurrency exchanges, and digital banks are frequent targets of these attacks. When a DDoS takes down a platform, traders cannot execute orders, close positions, or access their funds.
If you have open positions and the platform goes down, you cannot set stop-loss orders or close positions manually. The market continues to move while you are unable to access it. This can turn a controlled position into a significant loss.
Repeated attacks on a platform erode user trust. Traders migrate to services with better security infrastructure. For an exchange or broker, a DDoS attack causes not only technical damage but also reputational damage.
Users don’t always know that an attack is underway. These signs suggest it’s happening.
The platform becomes extremely slow. Pages take a long time to load, or orders don’t execute.
Frequent disconnections. The system repeatedly logs you out for no apparent reason.
Server error messages. Massive numbers of 503 errors or “service unavailable” messages.
The company reports the incident. Reputable platforms inform their users when they detect an attack.
If you suspect an attack, do not enter your credentials on alternative sites that appear to be your platform. Attackers sometimes combine DDoS attacks with phishing.
In 2020, several cryptocurrency exchanges suffered DDoS attacks during a sharp rise in Bitcoin’s price. Users were unable to log in to sell at peak prices or adjust their positions. By the time the platform was back online, the price had already corrected. Those affected lost opportunities and, in some cases, real money due to unprotected positions.
The negative reaction can make the problem worse.
Repeated attempts to log in further overload the system.
Clicking on alternative links may be a phishing attempt.
Not having stop-loss orders set up in advance.
You can’t prevent your platform from being attacked, but you can prepare for it.
Set stop-loss orders on all open positions as a standard practice.
Have access to the mobile app as an alternative.
Choose platforms with a solid track record of DDoS protection.
A DDoS attack overwhelms a server until it becomes inaccessible. In finance, that means losing access to your positions at the worst possible moment. User defense isn’t technical—it’s operational: configured stop-loss orders, reliable platforms, and staying calm when service goes down.
