There is no disputing the popularity of WordPress. As the leading CMS platform available (more than 70 million websites depend on WordPress), it is also under constant attack from hackers. Many of us have learned the hard way about just how vulnerable the CMS giant can be. If you run a large website or multiple websites with WordPress, it is likely you have been hacked or compromised at some point. Even if you were hacked before and managed to fix it, the threat may still be there silently waiting to attack again. This can happen by means of “backdoors” created by the original hacker.
My WordPress website was hacked AGAIN!
As I just mentioned, when your WordPress site gets hacked after you successfully diverted a previous attack, it’s usually because of a backdoor created by the hacker. Backdoors give hackers access to your website and files by bypassing normal procedures and getting authentication without you even knowing they are there. In this article, I’ll try to explain what a backdoor is, how to find it and hopefully how to rid it from your WordPress website.
