Fix and Prevent Website Defacement Attacks

by

Website defacement is a neon sign flashing your site has been hacked to every visitor to your site. It’s a highly visible and alarming breach of security that can leave you feeling embarrassed, frustrated, and vulnerable.

The first thing to do is scan your site for malware.

Furthermore, there are steps you can take to prevent your site from getting hacked and protect your online presence. This article will break down everything you need to know.

TL;DR: Scan your website immediately if your site has been maliciously defaced. MalCare has powerful scanning capabilities, automatic removal, and a top-notch firewall, you can regain control of your website in minutes.

What is website defacement attack?

Website defacement (or malicious defacement) is an attack where a hacker replaces your website content with their own, often mocking you or your organization. It’s like a digital graffiti artist painting on your website’s wall. And just like a graffiti artist, hackers often leave a signature to show off their skills.

🚨 Attacks like this can seem sudden and out of the blue, unless you use a daily malware scanner on your site. These attacks are usually caused by hackers installing malware, or exploiting vulnerabilities to gain access to your site. A malware scanner signals these issues early so you can prevent attacks like this in the future.

This type of attack is super popular and even big companies aren’t immune. In 2010, the European Union’s website for the Spanish president was hacked. Instead of pictures of the President, visitors were met with faces of fictional character Mr. Bean. 

While it may seem funny, website defacement is a serious breach of security and causes damage to online reputations. We are not here to debate whether or not some sites deserve the attack or not. So, let’s dive deeper into the preventative methods and fixes of this type of attack.

Step 1: Take the site offline

To take a WordPress site offline temporarily, you can use the maintenance mode feature provided by various WordPress plugins. These plugins allow you to display a customized message or a maintenance page to visitors while you work on your site behind the scenes. Simply install a maintenance mode plugin of your choice from the WordPress plugin directory, activate it, and configure the settings to enable maintenance mode. This will effectively take your WordPress site offline, displaying the maintenance page to visitors and preventing them from accessing the regular content until you are ready to bring the site back online.

Step 2: Investigate the attack

Scanning for malware is an essential step in ensuring the security and integrity of your WordPress site. By proactively detecting and removing malicious code, you can safeguard your website and protect your visitors’ sensitive information. There are three primary methods for scanning your WordPress site: utilizing a security plugin, using an online scanner, or performing manual scanning.

  1. Security Plugin Scanning: One of the most efficient ways to scan for malware is by using a reliable security plugin like MalCare. MalCare has gained a reputation as one of the top WordPress security plugins, offering advanced features and exceptional scanning capabilities. Its intelligent algorithms can detect both known and unknown malware, swiftly identifying any malicious code present on your website. With a user-friendly interface and real-time scanning, MalCare provides comprehensive protection and instant alerts in case of any suspicious activities.
  2. Online Scanner: Another option is to utilize online scanning services such as SiteCheck. These platforms analyze your website’s files and provide detailed reports on potential malware infections. While online scanners can be helpful for a quick overview, they might not offer the same level of accuracy and real-time protection as security plugins.
  3. Manual Scanning: For those who prefer a more hands-on approach, manual scanning involves inspecting your website’s files and directories for any signs of malware. This method requires a solid understanding of WordPress and coding, as well as specific knowledge of common malware signatures and patterns.

Step 3: Remove the malware

There are a few different ways to remove malware. So, starting from the easiest, here are your options:

Option 1: Automatic malware removal with security plugin

MalCare is an excellent tool to have in your arsenal when dealing with website defacement on WordPress sites. MalCare scans your entire website for malware, site files, and database included. 

Once the scan is complete, it will surgically remove malware from your WordPress site. This means you can have your site back in minutes. There is no need to wait for a security expert service to clean your site, no fees beyond a basic subscription, and a firewall at the end of it all to keep further attacks at bay.

So, why is automatic removal with MalCare the better option? Well, for starters, it’s fast and efficient. Instead of spending hours trying to identify and remove the malware yourself, MalCare can do it in just a few clicks. Plus, once the malware is removed, MalCare will detect vulnerabilities in your site that allowed the hackers in. 

Option 2: Malware removal with a specialist

While automatic removal with MalCare is usually the best option for removing malware, there are some cases where you might need to seek help from a specialist. However, it’s worth noting that this can be an expensive option, with some specialists charging hundreds of dollars for their services.

Additionally, these experts can be busy and may not be able to get to your website immediately. This can leave your website vulnerable to further attacks while you wait for assistance.

Because of these potential downsides, we recommend hiring a specialist only as a last resort. For instance, if your site has been taken offline by the host, and all you have is a backup to work with, then you may need to turn to a specialist for help.

That said, if you do decide to go this route, be sure to choose a reputable and experienced specialist to ensure that the job is done correctly.

    Option 3: Manual malware removal (NOT RECOMMENDED)

    Manual malware removal is often considered the worst option of the three. It’s a time-consuming and difficult process that requires a great deal of technical expertise. Plus, it’s often unreliable—even if you think you’ve removed all the malicious code, there’s always a chance that some may remain hidden in your website.

    The essence of manual malware removal is to compare the corrupt files with their clean counterparts to identify differences. Then, off those differences, you need to remove malicious code.  Here is a brief summary of all steps that go into manual malware removal:

      • Backup your website: Start with a full backup of your WordPress site before manual cleanup. In case of issues, you can restore it.
      • Download clean versions of WordPress core, themes and plugins:  Check the versions of your WordPress site, themes and plugins and download the clean versions. 
      • Reinstall WordPress core: With clean versions, begin WordPress malware cleanup. Reinstall core files by replacing ‘wp-admin’ and ‘wp-includes’ folders via cPanel or SFTP. Check ‘index.php,’ ‘wp-config.php,’ ‘wp-settings.php,’ ‘wp-load.php,’ and ‘.htaccess’ for malware. Delete suspicious code. Remove PHP files in ‘wp-uploads’ folder.
      • Clean themes and plugins files: To address malware in themes and plugins, navigate to the wp-content folder. Review each file, comparing them to fresh downloads, looking for suspicious code. Keep in mind that customized files may contain additional code. 
      • Clean malware from WordPress database tables: Remove malware from WordPress database tables via the admin panel. Check ‘wp_options’ and ‘wp_posts’ tables for suspicious content. Follow a detailed guide for effective cleaning.
      • Remove all backdoors: Now that you’ve removed the malware, keep your WordPress site secure by removing backdoors. Search for common backdoor keywords like eval, preg_replace, and delete them. Consider using a security plugin for extra help because it can be difficult to identify these backdoors. 
      • Reupload cleaned files: After cleanup, reupload files to your website using cPanel or SFTP, similar to manual backup restoration.
      • Clean the cache: Clear the WordPress cache to ensure a completely clean website after malware removal and avoid storing infected versions.
      • Verify each plugin and theme: To do this, disable all your plugins and themes and then reactivate them one by one. Look for changes in your website that could be caused by vulnerabilities.
      • Use a security scanner to confirm: It will serve you well to scan your site with a security plugin like MalCare. This will make sure you’ve removed everything you need to remove. 

            However, it’s worth noting that not all discrepancies between files are necessarily bad. It could just be custom code that’s unique to your website. Unfortunately, there’s no blueprint or library for malicious code. So you can only rely on your coding experience to identify and remove it.

            Given the challenges and risks involved, we strongly advise against attempting manual malware removal unless you have significant experience in website development and cybersecurity.

            Step 4: Post-cleanup checklist

            Now that you’ve taken care of the immediate threat of website defacement, it’s time to take a closer look at the aftermath. The post-hack period can be just as critical as the attack itself, and it’s important to take the right steps to secure your site and prevent future attacks. 

            1. Change passwords: One of the first things you should do after a website defacement is change all of your passwords associated with your website. This includes your hosting accounts, FTP accounts, and any user or admin accounts. Use strong passwords that are hard to guess and consider using different passwords for different accounts.
            2. Restore site content: Website defacement often results in damage or loss of content. If you have a recent backup, restore your site content. Don’t restore the whole site because this could cause the malware to be restored. So, if you need to restore blog posts, look for the right tables in the database to restore. If you’re looking to restore a WooCommerce site, restore the right product pages, checkout pages and whatever else you need. This ensures that your site is up-to-date, functional, and has all the content it needs to keep your users engaged.
            3. Check for unauthorized users: It is possible that hackers may have created unauthorized accounts on your website, which can be used to carry out further attacks. Check your user list and delete any suspicious accounts. If you’re unsure, look at the login history to see where and when someone has logged into your website.
            4. Scan for malware again: Once you’ve removed the defacement, it is important to scan your website again to ensure that it’s completely clean. MalCare, as mentioned before, is a great tool for this, and can help you identify any lingering malware.
            5. Check for vulnerabilities: Use MalCare to detect any vulnerabilities in plugins and themes. Then, look out for updates and safely update them. If there are none available, let the developers know so they can release an update as soon as possible.
            6. Notify users and customers: It’s important to let your users and customers know what happened. Send out an email or post on social media to notify them of the hack, explain what you have done to fix it, and give them any relevant information they need to protect themselves.

            While you may have removed the defacement and secured your website, it’s important to take measures to prevent further attacks. Check out the next section for tips on how to keep your website secure and avoid similar attacks in the future.

            Step 5: Website defacement prevention

            Preventing website defacement is the ultimate goal for website owners. It saves you the stress and time of dealing with a hacked site. In this section, we’ll discuss some proven and effective preventive measures you can take to secure your website and avoid the nightmare of a defaced site.

            • Install a firewall: A firewall acts as a barrier between your website and the internet, blocking malicious traffic and preventing unauthorized access to your website. There are different types of firewalls, including software-based and hardware-based options. But the easiest thing is to install a security plugin like MalCare that includes an advanced firewall designed for WordPress. MalCare’s firewall uses advanced algorithms to keep malware out. After multiple tests and comparisons with other security plugins, it has proven itself to be one of the best in the market. 
            • Install a plugin that scans for malware automatically and regularly: Malware scanners can help detect and remove malicious code from your website before it causes damage. MalCare does just that. It scans your site automatically, at regular intervals, and immediately notifies you of any issues. 
            • Take regular backups that you can restore: Regular backups of your website are essential in case of a hack or malware infection. Ensure that your backup system is reliable and that you can restore your website quickly if needed.
            • Use security measures like two-factor authentication: Two-factor authentication (2FA) adds an extra layer of security to your login process, requiring a second, real-time form of authentication (such as a code sent to your phone) in addition to your password. This helps to prevent unauthorized access to your website.
            • Keep everything up to date: It’s important to keep your website, plugins, and other software up to date with the latest security patches and bug fixes. Outdated software can be vulnerable to attacks and hacks.
            • Use strong passwords: Strong passwords are essential for protecting your website. Use a combination of upper and lower case letters, numbers, and symbols. Avoid using easily guessable passwords like “password” or “123456.”
            • Website defacement detection/monitoring: Website defacement detection or visual monitoring tools can help you detect when your website has been defaced. These tools monitor your website for changes and alert you when they detect a defacement. MalCare has built-in visual monitoring.
            • Watch out for files uploaded on your site: Be wary of files uploaded to your website by users or third-party plugins. Hackers can use these files to inject malware or malicious code into your website.
            • Limit access: Limit access to your website administrative areas to only those who need it. Restricting access can help prevent unauthorized changes to your website.
            • Use SSL: An SSL certificate provides a secure connection between your website and your users, encrypting data as it travels between the two. This can help prevent attacks like man-in-the-middle attacks.
            • Use reCaptcha: reCaptcha is a tool that helps prevent automated attacks on your website, like spam bots or brute force attacks. By requiring users to solve a captcha before submitting a form or logging in, you can prevent these attacks and keep your website secure.

            How can malicious defacement impact your website?

            Malicious defacement can have serious consequences for your online presence. In this section, we’ll explore how web defacement impacts your site and what you can do to prevent it from happening in the first place.

            • Loss of revenue: If your website is defaced, it can cause a loss of revenue as customers may not trust your site anymore, and you may lose sales or traffic. This can also affect your long-term success.
            • Loss of reputation: Website defacement can tarnish your brand’s reputation, making it more difficult to gain new customers or retain existing ones. This can have long-lasting effects on your business and require significant effort to regain trust.
            • Damage to customer trust: If your website is defaced, customers may feel that their personal information is no longer secure. This can lead to a loss of trust, which is difficult to regain.
            • Legal consequences: If a defacement leads to a data breach, there may be legal consequences and liabilities, such as fines or lawsuits.
            • Increased risk of further attacks: If your website is defaced, it may indicate that there are security vulnerabilities that hackers can exploit. This can increase the risk of further attacks and compromise the security of your website and data.
            • Loss of SEO ranking: Defacement can negatively impact your website’s SEO ranking as Google may flag it as a security risk and lower its ranking in search results. This can have a significant impact on your website’s traffic and visibility.

            • Disruption or damage: Other hackers may deface a website to cause disruption or damage to the website owner, perhaps as an act of revenge or to send a message.
            • Sensitive data or system access: In some cases, hackers may deface a website as a way to steal sensitive data or gain access to other systems connected to the website.
            • Testing security vulnerabilities: Hackers may use website defacement as a way to test the security vulnerabilities of a website for future attacks or to improve their own hacking skills.
            • Demonstrating skills or abilities: Some hackers may deface a website to show off their skills or abilities to the wider hacking community.
            • Ransom demands: Finally, in some cases, hackers may deface a website and demand a ransom payment from the website owner in exchange for restoring the website to its original state.
