In the modern world of cyber threats, reliable protection of servers and systems is one of the top priorities for business. Special attention should be paid to protection against rootkits, malware that imperceptibly hide their presence so that attackers can gain access to data. One of the popular tools for detecting and eliminating such threats is RKHunter (Rootkit Hunter). Every business and user who is worried about their safety should have such a tool. Thanks to RKHunter, you will be able to secure your data and the data of your users.

In this article, we will analyze what RKHunter is, how it works, why it is chosen by server administrators and what advantages it can give to your business.

What is RKHunter?

RKHunter is a free and open source tool designed to detect rootkits, Trojans, vulnerabilities and malicious configurations on Unix-like systems (Linux, macOS, FreeBSD). Rootkits are very dangerous viruses as they can very well hide their presence in the system not only from the user but also from most antivirus programs. RKHunter is constantly being updated, so it detects rootkits that even appeared not so long ago.

This tool analyzes the system, checks for malware, and evaluates the security of the configuration, providing recommendations on how to fix the identified problems. If you follow these recommendations, your system will be safe, and your data will not fall into the hands of intruders.

How does RKHunter work?

RKHunter scans the system for traces of rootkits and malicious changes in files, libraries and configurations. The main stages of his work: 

Installation

You can install RKHunter through the standard package managers. For example, in Ubuntu:

sudo apt install rkhunter  

Database initialization

Before the first launch, you need to update the database to get up-to-date signatures:

sudo rkhunter --update  

Scanning

To perform a system check, just run the command:
