How you can be notified if WP-VCD malware have attach on your website?
The best solutions ever I have seen to use Sucuri Platform, not only WP-VCD malware, it makes security a 5-minute affair: from a With a Web Application Firewall, On-demand Malware Scanner, self-managed Vulnerability Assessment & Penetration testing, Bug bounty program, all under one dashboard.
Also, you can use the Wordfence Plugin to scan your WordPress website form the WordPress dashboard. If the malware has found it shows this type of winning for wp-tmp.php malware.
The solution was simple. I was able to just trash/remove below files straight from the file manager on my hosting server (The root directory called, “public_html”).
However, the infected “functions.php” file was a bit tricky. The malware attack was placed on the existed theme file so can’t just remove it. You would have to edit the “functions.php” file to fix 100%. But, don’t panic. I will carefully show you what to edit from the file.
Use FTP program like Filezilla, or go to the Cpanel -> File Manager -> Root Directory – “wp-content” -> themes -> (your theme) -> functions.php. Open up the file, and remove the first set of PHP snippets code like below. In my case, remove the very first line of file to the line 184 until you see the ending PHP bracket
