Over a typical 3-month span, the average server has around 1500 kinds of malware injected into its files. Lately, a great many of these injections have been occurring in WordPress installations. What should you do when malicious code is injected into WordPress files?
You could delete or quarantine the files, but that will break WordPress and take the website down. The same is true for most content management systems. You could restore the files from a backup, but that might rewrite important changes to the files. You could also clean them up manually, but that’s troublesome and time-consuming.
A much better way to go is to employ Imunify’s automatic malware cleanup capabilities. Malware cleanup removes the infected part of the file, without touching the legitimate code. This keeps web sites up and running, preserves useful file changes, and saves a lot of effort.
To see the results of Imunify’s automatic malware cleanup, let’s take a look at an example of an infected WordPress file, in this case, index.php:
The highlighted code at the beginning is a simple backdoor (SMW-INJ-12525-php.bkdr-8) that’s been injected into the file.
Here’s the code of index.php after Imunify’s malware cleanup. It’s 100% identical to the original code of the file in a WordPress installation:
Imunify360/AV+’s capabilities are much more extensive than shown in the simple example above. It can cut multiple infections from various parts of a file, including highly obfuscated code. And, it does it in a fully automated way.
To enable automatic malware cleanup in Imunify360, just designate “Cleanup” as the “Default Action”, then specify the period of regular scans. There are instructions for how to do this in our blog post Configure Malware Scanner for maximum speed and efficiency with 3 new settings.
