Once you have downloaded the theme, you will find inside a folder with all files needed to change your premium theme. You can then edit these files and upload them on your server. Themes like this are also known as ‘Theme Forest’ or ‘Theme Forest Project’ (TF).

These themes have been uploaded by many developers over time and now become available for download via various file sharing sites like Rapidshare, Depositfiles and Mediafire etc

Disadvantages of Nulled Themes

  1.  The biggest disadvantage of using a nulled theme is that it’s not officially developed by the original developer. That means there are chances that you’ll run into a lot of bugs and issues, especially if you don’t know how to troubleshoot them.
  2. If you are using a nulled theme, there is no guarantee that the theme will work on all devices or in all browsers
  3. No support from the developer.
  4. May not be updated in future. You may not be able to update your theme without downloading the original files from the developer site.
  5. Some Nulled themes are not compatible with plugins and extensions, which means if you want to add a feature in your website, you will have to install those separately.
  6. These themes mostly come up with the backdoor hack for entering your website which loosens the website security and makes it prone to hacking and common malware infections like Japanese keywords hack & WordPress malware redirect.

? Is Your WordPress Theme infected with Malware?

WordPress is featuring premium themes in its latest versions which are highly secure and malware insusceptible. Unfortunately when it comes to free themes, they are the most easily targeted preys for web attackers. The reason behind is that downloading a free theme from an unknown source or pirated websites may affect the security of your websites.

Such themes are poorly coded and lead to create unauthorized access to websites through loopholes. An unknown source of theme may be created by a hacker who tweaks it for their own profits. There are several reasons behind the exploitation of such themes.

Some of the common reasons are:

  • ​To get a back link from the blog posts on your websites
  • For redirecting your website to spam links
  • To add adverts.
  • To create a backdoor to your website

Impact Of Malware Infected WordPress Theme

An infected theme can lead to many different problems.

First of all, it could damage your website. This could cause your site to act in an unexpected way or even crash. It could also slow down your site and make it inaccessible for visitors.

The worst case scenario is that the infection will steal all your blog’s content and put it on another website – a malware distributor. This would be devastating for your business as you will lose all your revenue and traffic overnight.

You should always make sure that the theme you are going to install on your WordPress site is not infected before you install it. You can do this by using a virus scanner or by looking at the reviews on the official website of the developer.

1) Malicious code embedded in the theme will be executed by the server every time a user visits your website. The code may include a backdoor or virus, which infects the files on your server and damages them.

2) If you purchase a premium theme from an untrusted seller, there may be malicious code inserted into it by the seller before they sell it to you. They may do this so that they can spy on their customers and steal their data (for example: credit card details). When you install this theme onto your website, the malware will run automatically and collect information about you and other visitors to your website. This can lead to identity theft, credit card fraud and other financial crimes being committed against you or other people visiting your website using infected themes downloaded from untrusted sellers

If you are using a premium theme for your website, then it is a good idea to check for the latest security updates regularly. A lot of times, security patches are released for themes to ensure that they are safe to use.

If you are using an untrusted theme, then it will be better if you can uninstall it and install a new one that has been verified by the WordPress team. It is important to keep your website secure because a compromise could lead to loss of revenue and reputation.

Apart from installing an infected theme, there are several other ways in which your WordPress website can be hacked or compromised. You can get infected by visiting websites that have malicious content on them or by clicking on a link that contains malware. There are also chances that your website can get hacked if you are using an outdated version of PHP or MySQL database server software.

If you want to stay away from all these wordpress security issues and keep your website secure at all times.
