Installing Linux Malware Detect
Posted by on 23 October 2012 01:58 AM

This guide will walk you through installing LMD (Linux Malware Detect) on your VPS/Dedicated server

You will need to be logged in as root to the server over SSH.

Let's create a temporary directory and navigate into it, followed by downloading the latest release of maldet:

mkdir tmp
cd tmp

Extract the archive containing LMD and navigate into the directory it creates:

tar xf maldetect-current.tar.gz && cd maldetect-1.4.1

Warning: Version may vary, you can check the current directory listing with the command `ls`

Once you're inside execute the install script:


This will automatically install a cronjob inside /etc/cron.daily/maldet as well, it will make LMD execute daily and scan local cPanel accounts for possible malware.

Usage is fairly simple, to scan user's home directory or any other directory you would simply execute:

maldet -a /home/user

Any path is alright.

Please note that LMD runs great with ClamAV, if you'd like to install ClamAV on a cPanel based server, review this article.

Setting up e-mail alerts

LMD has an option to alert you each time it detects malware, please review these configuration variables inside /usr/local/maldetect/conf.maldet

variable value description
email_alert 1 or 0 enable or disable e-mail alerts
email_addr  e-mail address  target e-mail for notifications, should be put in quotes like: ""

Other configuration variables that you should look into:

variable value description
quar_hits number if the number is different than 0, enables automatic quarantine
maxfilesize  size  makes LMD skip files larger than set size, for example "512k" (512 KB)
