Maldet (Linux Malware Detect) is a free and open-source malware scanner designed to detect malicious software on Linux systems. It can be used to scan for known threats, such as rootkits, backdoors, worms, and trojans. Maldet is an effective tool for monitoring the security of your DirectAdmin server. This guide will walk you through how to install maldet on a DirectAdmin server.

Step 1: Install Dependencies
Before we can install maldet, we need to ensure that all its dependencies are installed on the system first. To do this, run the following commands as root:

yum install gcc make perl-Time-HiRes wget tar gzip unrar zip bzip2 lha arj p7zip -y;
yum groupinstall "Development Tools" -y;

Step 2: Download Maldet
Next, download maldet from its official website using wget command:

wget http://www.rfxn.com/downloads/maldetect-current.tar.gz;

 Step 3: Extract & Install Maldet

Now extract the downloaded archive with tar command followed by the installation process by running the below commands one after another in the same sequence :

tar xfz maldetect* && cd maldet*/ && ./installer ;cd /usr/local/maldetect ;./installdir ;./filescanner --update ;crontab -e 0 */6 * * * /usr/local/maldetect/filescanner --report > /dev/null 2>&1

This adds a cron job that runs every 6 hours and sends any reports generated directly into “null” so it doesn’t get emailed out or clutter up your inboxes with emails about potential infection attempts etc… The cronjob should look something like this when done correctly :

0 */6 * * * /usr/local//maldetscan –report > dev null 2>&1

You can adjust this setting if needed but it isn’t necessary unless you want more frequent scans than once every six hours.

Installing Maldet

Maldet, short for Linux Malware Detect, is a malware scanner that scans files and directories on your server in order to detect malicious software such as Trojans, worms, rootkits and other threats. Installing Maldet is relatively simple and can be done with just a few commands. First, you’ll need to make sure the prerequisites are installed. This includes ClamAV (a virus scanning engine) and Libiconv (for character set conversion). After installing these packages you’ll need to download the latest version of Maldet from their website: http://www.rfxn.com/downloads/maldetect-current.tar.gz Once downloaded extract the contents of the tar file: tar -xzf maldetect-current.tar Now change into the directory where it was extracted: cd maldetect-*

Finally, install Maldet by running this command:

./install.sh

You should now have Maldet installed on your system! To use it simply type ‘maldet’ followed by any arguments or options needed for your scan type (such as ‘–scan-all /var/www’). For more information about using Maldet please refer to their documentation available at rfxn.com/appdocs/README.maldetect

Preparing the Server

Before a server is ready to serve its purpose, there are several steps that must be taken, which in case you have a Managed Server with us is already taken care by our experienced Admins. First, you need to ensure that your server is running an operating system (OS) that is compatible with the type of applications and services you will be hosting. Once an OS has been selected, it needs to be properly configured and secured for use.

This includes installing security patches and updates, setting up access controls such as user authentication protocols, configuring firewalls to limit external access only to necessary ports/services, disabling unnecessary services or accounts on the machine in order to reduce attack surface area, hardening network settings such as hiding open ports from public view etc. Furthermore, if any additional software packages are needed for specific purposes then these should also be installed at this time.

After the initial setup phase has been completed successfully it’s important to keep regular backups of all critical data stored on the server so that in case of any unforeseen events or disasters this can easily be restored without too much hassle. Finally, there should always be a monitoring solution in place that allows administrators to get real-time alerts when something goes wrong with their servers so they can take immediate action accordingly.

Configuring Maldet

Maldet, also known as Linux Malware Detect, is a malware scanner for Linux systems. It’s an open-source program that uses threat intelligence to detect malicious files on your system. It can scan for viruses, Trojans, rootkits, and other types of malware. To get the most out of Maldet you need to configure it properly. Here are some tips on how to do that:

First off, make sure you have the latest version installed. To do this just type “maldet –version” in your terminal and check if it matches the latest version available from their website or Github repository. If not then upgrade using yum or apt-get depending on which package manager you use.

Next up you need to decide what directories should be scanned by Maldet when performing a scan. This can be done via either command line arguments or by editing its configuration file located at /usr/local/maldetect/conf/. You’ll want to add any important directories such as webroot folders, user home directories etc into this list so they’re scanned regularly for any potential threats.

You’ll also want to set up email notifications so that you know when something has been detected on your system and needs attention immediately (especially if running cron jobs). For this edit the conf file again but look for the section labeled “email_alert” – here enter all relevant details such as email address(es) where alerts will be sent along with SMTP settings etc…

Finally, there are some additional options available through Maldets’ command line interface (CLI) which allow further customization of scans such as intensity levels (how deep it looks into archives), scan speed limits etc… These can all be found by typing “maldet –help” in your terminal window which will display a full list of CLI commands along with descriptions about each one’s purpose and usage guidelines

Installing Maldet in a DirectAdmin Server

Maldet, or Linux Malware Detect, is an open-source malware scanner for Unix systems. Installing maldet on a DirectAdmin server can help to detect and quarantine malicious files that have been uploaded to the server.

To install maldet on your DirectAdmin server, you first need to download the installation script from the official website: https://www.rfxn.com/downloads/maldetect-current.tar.gz . Once it is downloaded, upload it via FTP to your home directory (usually /home/username).
Next, connect to your server using SSH and extract the file by running this command: tar -xvzf maldetect-current.tar.gz . This will create a folder called “maldetect” in your current directory with all of its contents inside it.
Run the following command within that directory: sh ./install.sh , which will start up Maldet’s automated installation process and automatically update any existing version of Maldet already installed on your system if necessary. The installer will prompt you for confirmation before proceeding with installation so make sure you approve each step as prompted until the completion of setup when “Installation Completed” message appears at the end of the console output logs.. That’s all! Now you are ready to use Linux Malware Detect (LMD) on your DirectAdmin Server!
