Rkhunter: A Powerful Tool for Securing Your System
If you’re distressed about the security of your system, you need a reliable tool to help you detect and remove potential threats. One such tool is Rkhunter (Rootkit Hunter), a powerful and flexible tool that scans your system for rootkits, backdoors, and other security threats.
What is Rkhunter?
Rkhunter is a command-line utility that scans your system for security threats. It’s designed to detect rootkits, malicious software that can give attackers remote access to your system, and other hazards, such as backdoors and local exploits. Rkhunter is written in shell script and is available for various operating systems, including Linux and Unix.
How Does Rkhunter Work?
Rkhunter works by comparing the current state of your system to a known good condition. It scans your system for signs of suspicious activity, such as files or processes that have been modified or added without your knowledge. It also checks your system for known vulnerabilities and potential exploits.
If Rkhunter finds anything suspicious, it alerts you so that you can investigate further. One of the critical features of Rkhunter is its use of file signatures to detect rootkits. Rkhunter maintains a database of known rootkit signatures, which it uses to compare against the files on your system. If it finds a file that matches a known rootkit signature, it alerts you so that you can take action to remove the rootkit.
Using Rkhunter
Using Rkhunter is straightforward. Once installed on your system, you can run it from the command line by typing “rkhunter –check.” Rkhunter will then scan your system for security threats and generate a report of any potential issues.
It would be best to run Rkhunter regularly, at least once a week, to ensure your system remains secure. You can also schedule Rkhunter to run automatically using cron, a tool for organizing tasks on Unix-based systems.
In addition to its scanning capabilities, Rkhunter also includes several other features to help you secure your system. For example, it can check the integrity of your system binaries and configuration files and scan your system for known vulnerabilities.
Rkhunter Conclusion:
If you’re distressed about the security of your system, Rkhunter is a tool you should consider. It’s a powerful, flexible utility that can help you detect and remove potential threats. By regularly scanning your system with Rkhunter, you can ensure that it remains secure and that you’re alerted to any potential security issues as soon as they arise.

We will walk you through the installation and configuration of Rkhunter on Debian 10.
Step 1: Configure the VPSie cloud server
- Sign in to your system or register a newly created one by logging in to your VPSie account.
- Connect by SSH using the credentials we emailed you.
- Once logged into your Debian instance, run these commands to update your system.
apt-get update && apt-get upgrade -y
Step 2: Installing Rkhunter
Installing Rkhunter requires the following,
sudo apt install rkhunter -y
Step 3: Installing Rkhunter
To keep track of all possible threats, Rkhunter stores information in data files. You should be aware that the default Debian configuration cannot update files. Follow these steps to resolve this issue,
- Using nano, edit the /etc/rkhunter.conf file.
sudo nano /etc/rkhunter.conf
- To search, press CTRL + W and type WEB_CMD = “/ bin / false“. You can disable the statement by adding a # at the beginning of the line.
# WEB_CMD="/bin/false"
- Use CTRL + W to locate UPDATE_MIRROR.
Update the UPDATE_MIRRORS value to 1.
UPDATE_MIRRORS=1
- To search for MIRRORS_MODE, press CTRL + W.
- In MIRRORS_MODE, set the value to 0.
MIRRORS_MODE=0
- When done, save the document and close it.
Step 4: Verify the configuration file
sudo rkhunter -C
Step 5: Update the data files and perform a local system check
Update data files,
sudo rkhunter --update
Check the local system,
sudo rkhunter --check
