This guide explains the security steps you can take to protect your WordPress site from constant brute force attacks. It covers the signs of attacks, their effects, and effective protection methods in detail. It also explains what to do after a successful attack and common wrong practices.
What Is a WordPress Brute Force Attack?
Brute force attacks are attacks where a hacker tries to gain unauthorized access to a site by trying username and password combinations. These attacks usually try to guess passwords using dictionary words, so they are also called dictionary attacks.
Since bots can attack from different IP addresses, only blocking IPs is not enough. Because of this, it is important to use an effective WordPress firewall and provide bot protection.
Protection Methods Against Brute Force Attacks
Bot Protection
WordPress firewall plugins that offer smart bot protection, like MalCare, block malicious bots from accessing the site.
Limit Login Attempts
By limiting wrong password attempts, you prevent brute force bots from trying many combinations in a short time.
Two-Factor Authentication
You can increase security by strengthening user verification with dynamic login tokens, OTP, QR code.
Firewall and Password Security
Firewalls block traffic from bad IP addresses and prevent server resources from being overused. MalCare proactively blocks bad IPs using data from more than 400,000 sites.
Using strong and unique passwords is the most basic defense against brute force attacks. Password managers should be used to create complex passwords that are not reused. Also, in suspicious situations, forcing a reset of all passwords is recommended.
Extra Security Measures and Account Management
Disabling the XML-RPC feature reduces brute force attacks as an alternative login path. It is also important to review user accounts regularly and remove unused accounts.
Users should have only the minimum permissions they need. Geoblocking should be used carefully, only to block bad traffic from certain regions.
Signs of Brute Force Attacks
- Repeated wrong password entries
- Sudden slowdown in site speed
- Suspicious or unusual login times
- Increase in IP blocking notifications
- Excessive use of server resources
If these signs are noticed early, quick action can be taken against the attack and your site can stay secure.
Effects of Brute Force Attacks and Dealing with Successful Attacks
During an attack, server resources are quickly exhausted, the site slows down or becomes completely inaccessible. In successful attacks, the site can be infected with malware, and the site can be used as a botnet for other attacks.
After a successful attack, it is critical to quickly scan and clean your site with tools like MalCare, and increase protection measures.
Wrong Practices Against Brute Force Attacks and Conclusion
Password protecting the wp-admin directory can break AJAX functions and is not recommended. Changing the login URL is also not advised because it is hard to recover if it is lost.
Avoiding the admin username has limited benefit and can make management harder. The most effective method is layered security measures such as strong passwords, bot protection, and limiting login attempts.
