It has come to our attention that some of our customers have attempted to use 'nulled' (cracked/pirated) plugins and themes on WPX Hosting; this is grounds for immediate and permanent non-refundable termination of hosting accounts, as per our Terms of Service.
Most of these cracked plugins have hidden, malicious backdoor scripts.
That is why nulled plugins & themes are FORBIDDEN on WPX Hosting.
Some commercial plugins and themes can be found for free on seemingly legitimate websites where it seems safe to download. Nothing on these safe-looking websites appears to suggest that the plugins or themes offered there are infected with a very powerful backdoor script called CryptoPHP.
What can CryptoPHP do?
After being installed on a webserver, the backdoor has several ways of being controlled, including command and control server communication, mail communication, and even manual control.
Backdoors of this type are mainly used for illegal search engine optimization, also known as Blackhat SEO. The backdoor is a well-developed piece of code and dynamic in its use. The capabilities of the CryptoPHP backdoor include:
When installed, it can actually integrate itself deep into your website and use its functions, code, and database. It can add additional administrator user, add/delete/modify the content of the website, change your websites settings and anything you can or can’t imagine.
So we HIGHLY recommend ONLY using plugins from TRUSTED SOURCES.
Here is a list of some of the websites that distribute plugins with CryptoPHP backdoor:
The following websites host the actual plugin and theme files used for direct download:
If you have installed a nulled plugin or theme from one of these websites, it is very likely that your website could be infected with CryptoPHP.
The least you can do is delete the dangerous plugins/themes, check whether you have an additional admin user added, and ensure that all your websites look like they should for search engines.
You can do that from Google Webmasters Tools → Fetch as Googlebot .
