you may see on the internet some ads about payed wordpress themes for free cloned and nulled wordpress themes are NOT SAFE for many reasons we will talk about it today
As we define nulled it refers to premium WordPress plugins or themes that have been hacked or contain modified code designed to cause harm or collect information. These are obtained from a third-party website (not the original author or creator) and sometimes are made to work without a license key
most of these nulled and cloned wordpress theme are published on internet by hackers who hack a website with premium wordpress theme and download it , a hacker can download the source code of the website files if he successed uploading a backdoor to the website we talk more about that in websites security
so the hacker access now the source code and download it , most of hacker added some malicious code in the php files of the cloned and nulled wordpress theme , so you will be hacked if you download those themes and upload it to your website
other way you will have some legal problems abusing copyrights of others and you may end up with suspendingyour host account and maybe in court 🙂 so in total DO NOT UPLOAD CLONED AND NULLED WORDPRESS THEMES TO YOUR HOST
