Redirecting to a phishing site can be a nightmare, but the good news is that you can prevent it by being vigilant and taking some simple steps.
Malicious websites can be hidden behind legitimate-looking URLs, which can make them difficult to spot.
To prevent website redirecting to a phishing site, you need to be cautious when clicking on links or downloading attachments from unknown sources.
In fact, 74% of phishing attacks involve a malicious link or attachment.
What is a Malicious Redirect?
A malicious redirect is code, usually Javascript, that's inserted into a website with the intent of redirecting the site visitor to another website. This type of malware can have serious implications, exploiting potential vulnerabilities in a site visitor's computer.
Hackers often use malicious redirects to drive traffic to websites that contain advertisements for dubious products or services. They get paid a fraction of a cent for every ad click or impression they generate.

Malicious redirects can also be used to send you to fraudulent websites where you're encouraged to enter sensitive information. This information is then sent directly to the criminals, who can use it to commit identity fraud.
A malicious redirect can be inserted into a website in various ways, including through a poorly coded plugin. For example, a typical WordPress website redirect hack might involve the following steps:
- An inexperienced developer releases a plugin.
- A WordPress website owner installs the plugin, not realizing it contains security vulnerabilities.
- Attackers use a bot to scan the web for specific code to identify sites that have installed the plugin.
- Attackers inject custom code into the target websites.
Some common places where malicious redirect code is inserted include the index.php, index.html, .htaccess file, theme files, footer.php, header.php, and functions.php files.
Here are some examples of how malicious redirects can be used by hackers:
Identifying and Preventing Malicious Redirects
Malicious redirects can be inserted into your website through poorly coded plugins, which can be installed by inexperienced developers. These plugins can contain security vulnerabilities that attackers can exploit to inject custom code into your site.
Attackers often scan the web for specific code to identify sites that have installed vulnerable plugins, and then inject their malicious code into the target websites. This code is usually inserted in places like index.php, index.html, .htaccess file, theme files, footer.php, header.php, or functions.php.
A typical malicious redirect hack might look like this: an attacker injects custom code into your website, which is then executed when a user visits the page, sending them to a dodgy website. Server administrators are often powerless to resolve the issue because it's not a problem with the server – the website owner has intentionally installed the plugin code.
Malicious redirects can be caused by a variety of methods, including .htaccess redirects, Javascript redirects, and HTTP header redirects. In rare cases, you might find a META HTTP-EQUIV=REFRESH redirect, but these are less common.
Some common places where hackers will insert their malicious code to cause a WordPress redirect hack to happen include:
- Index.php
- Index.html
- .htaccess file
- Theme files
- Footer.php
- Header.php
- Functions.php
To prevent malicious redirects, it's essential to keep your plugins up to date and only install plugins from reputable sources. You should also regularly scan your website for malware and monitor your website's traffic for any suspicious activity.
Consequences and Recovery
Restoring from a known good backup is the fastest way to recover from a malicious redirect hack.
If you're running a site with frequently changing content, a good recent backup and intrusion detection are crucial to catch problems quickly.
To minimize downtime, you should turn to your access logs to determine how the hacker gained access to place the redirect.

Need to take site down?
If your site is redirecting to a place that might harm a user's computer, taking it down for maintenance is a good idea. This can prevent further damage.
You might want to temporarily take your site down if you suspect a hacker is still active on the site. In this case, making it inaccessible can prevent further damage.
Even a small change in the database can bring your site down or keep it from loading properly, so be extremely careful before making any changes.
Here's a list of common places where malicious code is injected:
- Index.php
- Index.html
- .htaccess file
- Theme files
- Footer.php
- Header.php
- Functions.php
Quick Recovery from Malicious Redirect
Recovering from a malicious redirect quickly is crucial to minimize downtime and prevent further damage. To do this, you should have a recent backup of your site that contains a good copy of your site.
Restoring your site from a known good backup is an excellent way to get your site back up and running quickly. If you're running a site with frequent content changes, a good recent backup and intrusion detection are essential to catch problems quickly.
You can determine how the hacker got in to place the redirect by examining your access logs. This will help you understand the extent of the problem and prevent future attacks.
To quickly recover from a malicious redirect, follow these steps:
- Restore your site from a known good backup.
- Examine your access logs to determine how the hacker got in.
- Update your plugins and themes to prevent future attacks.
- Install intrusion detection to catch problems quickly.
Remember, a good recent backup is essential to quickly recover from a malicious redirect.
Scanning and Security
If you suspect your site has been infected with redirect malware, scanning is the first step towards removal.
A recent clean backup is essential for successful malware removal, but even without one, you can still remove malware on your own.
You'll need to look for more than just redirect malware, as it often comes with other malware like backdoors and rogue admin users.
iThemes Security Pro's File Change Detection feature alerts you to file changes, which can indicate a redirect hack or backdoors.
Here's a recommended malware removal process: preserve evidence of the hack, consider it a crime scene, and investigate file timestamps to determine the intrusion vector.
A typical WordPress website redirect hack involves a poorly coded plugin, an inexperienced developer, and a bot scanning the web for specific code.
Attackers inject custom code into target websites in various places, including index.php, index.html, .htaccess file, theme files, footer.php, header.php, and functions.php.
Server administrators are often powerless to resolve the issue, as it's not a problem with the server, but rather the website owner's intentional installation of the plugin code.
To prevent future attacks, prioritize website protection, which enables businesses to fortify defenses and safeguard their online presence.
Robust website protection is the shield that stands between your business and relentless cyber attacks.
Here are some common places where attackers inject custom code:
- Index.php
- Index.html
- .htaccess file
- Theme files
- Footer.php
- Header.php
- Functions.php
Taking a holistic approach towards malware removal ensures that the redirection problem won't come back.
WordPress Specific Issues
A typical WordPress website redirect hack can be caused by a poorly coded plugin, which is then installed by a website owner without realizing its security vulnerabilities.
Attackers use bots to scan the web for specific code to identify sites that have installed the plugin, and then inject custom code into the target websites.
The malicious code is often inserted in one of the following places: Index.phpIndex.html.htaccess fileTheme filesFooter.phpHeader.phpFunctions.php
The wp_options and wp_posts tables in the WordPress database are typically targeted by hackers inserting malicious redirects.
Javascript code can be found embedded into each of your posts or even all of them, making it a common place to look for redirections.
In some cases, redirections can be hidden in widgets, making it harder to detect.
It's essential to preserve the evidence of what has happened, considering any hack a crime scene, and use file timestamps to determine how the intrusion happened and prevent it from happening again.
