Your web server's image processor could be malware hiding in plain sight.
I'm going to describe an interesting type of malware the Malware Intelligence Team recently uncovered during a recent research operation.
At the time of writing, there were 11,320 cases of it detected and neutralized on 265 websites across 183 servers.
It is a particularly ingenious and potentially destructive type of malware: it is designed to appear as a legitimate image processor, and can act as a backdoor to your web server.
A backdoor is malicious software that lets a hacker get back into your server even after you detect and remove their access credentials. When a hacker gets into your site, the first thing they do is upload a backdoor.

In Imunify360 v4.2 beta, we introduced “Hooks”, a new way to handle asynchronous events coming from the Imunify agent. It works like a simple event handler. For example, you can create a script that will run when malware is detected (right after the on-demand or background scan is finished).
The script is put on the server and registered via the Imunify360 command-line interface. In the script, you can specify a set of actions based on the scanning report received from Imunify360: for example, suspend a user account infected with malware, send out an email notification, or submit a ticket for the client. Hooks are just executables, so they can be written in any language (bash, php, python, etc.).
We’ve had a lot of questions regarding the practical use of hooks. So, we’ve created this article to show you an example of a hook that runs when malware is detected, and suspends the cPanel user account when the number of infected files exceeds three.
Here are the steps to create the hook:
Create a file (e.g. /root/hooks/hook.php) with the following content:
