The Ultimate WordPress Security Guide To Prevent Hacking & Malware Attacks
Old Software Security Risks
Dangers of Outdated Code
Running outdated WordPress software puts websites at serious risk of hacking. In fact, Patchstack reported a 24% jump in new WordPress security vulnerabilities in 2023 compared to the previous year [4]. Shockingly, 94% of these vulnerabilities were tied to plugins, not the WordPress core itself [4].
Here’s why outdated code is a problem:
| Component | Risk Factors |
|---|---|
| Plugins & Themes | Abandoned updates, known security flaws |
| Core WordPress | Slow security fixes, compatibility gaps |
| Infected Sites | Easy prey for automated hacking tools |
The situation worsens when users download plugins or themes from unverified sources, which can introduce harmful code. Fixing outdated software issues should be a top priority before setting up a solid update plan.
How to Keep WordPress Updated
The best way to reduce risks is by staying on top of updates. WordPress 5.5 made this easier by allowing automatic updates for plugins and themes. The system now checks for updates twice a day and sends email notifications after any auto-update [5].
Here are some tips to manage updates effectively:
- Turn On Auto-Updates: Enable automatic updates for minor WordPress core changes and security fixes.
- Back Up Regularly: Set up automated backups before updates to prevent data loss.
- Check Plugin Health: Remove plugins that are no longer maintained by their developers.
To keep your site secure, stick to a maintenance routine that includes:
- Weekly checks for updates.
- Monthly reviews of all installed plugins and themes.
- Quarterly evaluations of plugin usefulness and performance.
- Compatibility tests before applying major updates.
Login Security Problems
Password and Username Risks
Weak login credentials pose a serious security threat. Surprisingly, "password" and similar variations were still among the most used passwords in 2020 [7]. This shows that many users neglect even the most basic security measures.
Here are some common risks and their potential impacts:
| Risk Factor | Security Impact |
|---|---|
| Default "admin" username | Makes brute force attacks easier |
| Weak passwords | Easily cracked using dictionary-based attacks |
| Single-factor authentication | Lacks an extra layer of protection |
| Unlimited login attempts | Allows attackers to use automated attack tools |
Many users still rely on the default "admin" username, which simplifies brute force attacks [6]. Weak login practices like these can make your site an easy target. Strengthening your login security is essential to reduce these vulnerabilities.
Better Login Security Methods
To improve your site’s protection, consider implementing these measures:
Strong Password Requirements
Encourage users to create passwords that are 10–50 characters long and include a mix of uppercase letters, lowercase letters, numbers, and special characters [7]. Instead of single words, password phrases can be more secure and easier to remember.
"WordPress password security is crucial for your website, it keeps out attackers and bots looking for low-hanging fruit." [7] – MalCare
Two-Factor Authentication (2FA)
Add an extra layer of security by using authenticator apps such as Authy, LastPass Authenticator, or 1Password [8]. These apps also provide account recovery options, so you won’t get locked out if you lose access to your device.
Recommended Plugins
For additional protection, you can install security plugins:
- All-In-One Security (AIOS) Premium: Priced at $70/year, this plugin is trusted by over 1 million users and has a 5-star rating [9].
- Limit Login Attempts Reloaded: With a 4.9/5 rating and over 2 million active users, this plugin is another excellent choice [10].
In February 2024, Limit Login Attempts Reloaded released version 2.26.15, bringing important updates for WordPress 6.7 compatibility and improved GDPR compliance for WooCommerce login pages [10].

Malware Protection Steps
Types of WordPress Malware
In 2021, 60.04% of infected websites had at least one backdoor [11], making it a major threat. Backdoors allow hackers to create hidden entry points for ongoing access to your site.
Here are some common types of malware that target WordPress sites:
| Malware Type | Description | Warning Signs |
|---|---|---|
| Backdoors | Hidden access points for hackers | Unexpected admin accounts, altered files |
| Redirects | Sends visitors to malicious websites | Reports of strange redirects by users |
| Code Injections | Inserts harmful code into your files | Unusual pop-ups, slow site performance |
| Session Hijacking | Steals user session data | Unauthorized admin access, compromised accounts |
For example, in March 2024, a vulnerability in the Popup Builder plugin put over 100,000 sites at risk of malware infection [3]. Similarly, a flaw in the Beautiful Cookie Consent Banner plugin exposed 1.5 million WordPress sites to session hijacking attacks [3]. The next section covers tools and strategies to detect and eliminate such threats.
Security Tools and Scans
To effectively detect and combat WordPress malware, you need advanced tools and consistent security practices. Automated daily scans and premium security solutions are key to keeping your site safe.
WordPress sites face around 13,000 hack attempts every day [14]. Tools like MalCare use advanced algorithms to identify malware beyond basic file matching [13]. For businesses needing higher-level protection, Astra Security offers scanning services starting at $199/month [12].
If malware is detected, take these steps immediately:
- Enable maintenance mode and back up your site entirely before starting cleanup.
- Clean infected files and databases.
- Remove any suspicious code.
- Reset all passwords to secure your accounts.
- Submit a review request through Google Search Console.
"The first step to removing malware from your site is to scan it with MalCare. Then use the one-click malware removal feature to auto-clean your site in minutes. Remember that malware gets worse the longer it remains on your site, so act fast." [13] – MalCare
Stopping Brute Force Attacks
What Brute Force Attacks Do
Brute force attacks pose a persistent threat to WordPress sites. As WordPress.org explains, "Unlike hacks that focus on vulnerabilities in software, a Brute Force Attack aims at being the simplest kind of method to gain access to a site: it tries usernames and passwords, over and over again, until it gets in" [2].
In late 2021, brute force attempts surged by 160%, making up 5% of confirmed breaches. Security company Sucuri reported blocking 450,000 attacks in just three months [17][16][15].
When successful, brute force attacks can:
- Grant hackers full administrative access
- Allow installation of malicious software
- Steal sensitive user information
- Wipe entire websites
- Overload servers, leading to crashes
To reduce these risks, it’s crucial to use specific tools and strategies designed to protect your site.
Login Protection Tools
Defending against brute force attacks requires a layered approach. Below is a comparison of popular security tools:
| Protection Method | Free Option | Premium Starting Price | Key Features |
|---|---|---|---|
| Wordfence | Yes | $99/year | Real-time IP blocking, firewall |
| Sucuri | No | $199.99/year | WAF, geo-blocking |
| iThemes Security | Yes | $80/year | Network protection, reCAPTCHA |
| Jetpack | Yes | Free | Global IP database check |
To strengthen your defenses, consider these steps:
-
Install a Brute Force Protection Plugin
Plugins like Limit Login Attempts Reloaded can safeguard login pages, XML-RPC, and WooCommerce interfaces [10]. They also send instant email alerts for lockouts and let you customize login attempt limits. -
Enable Two-Factor Authentication (2FA)
Adding 2FA makes it much harder for automated attacks to succeed. Premium tools like iThemes Security provide advanced options, including real-time security dashboards [17]. -
Set Up Server-Level Protection
As WordPress.org puts it, brute force attacks target "the weakest link in any website’s security… you" [2]. Strengthen your server with these measures:- Password-protect the
wp-login.phpfile - Restrict access to
wp-login.phpby IP - Disable XML-RPC if unnecessary
- Use a web application firewall (WAF)
- Password-protect the
Combining these layers of security is the best way to protect your site. For example, pairing Wordfence’s free version with Limit Login Attempts Reloaded offers strong defenses like IP blocking and login attempt limits, all while keeping costs low for smaller websites [17].
Conclusion: Security Action Plan
