Getting Started with Karkinos
System Requirements
Before installing these penetration testing tools for beginners, ensure your system meets the basic requirements:
- Any server capable of hosting PHP
- PHP 7.4.9 or newer
- Python 3.8 or higher
- Pip3 package manager
- SQLite3 extension enabled
Installation Process
For Linux/BSD Systems:
- Clone the repository:
git clone https://github.com/helich0pper/Karkinos.git cd Karkinos
- Install Python dependencies:
pip3 install -r requirements.txt
- Prepare wordlists:
cd wordlists && unzip passlist.zip
- Configure database permissions:
chmod 755 db/main.db
- Enable SQLite3 in PHP:
sudo apt-get install php-sqlite3
For Windows Systems:
The process is similar, with the main difference being the SQLite3 configuration. Enable extension=php_sqlite3.dll
in your php.ini file instead of installing via package manager.
Important Configuration Notes
Karkinos uses specific ports (5555, 5556, 5557) for its modules. If these conflict with existing services, you can modify the port settings in:
/bin/Server/app.py Line 87 /bin/Busting/app.py Line 155 /bin/PortScan/app.py Line 128
Important: Using the built-in web server php -S 127.0.0.1:8888
in the Karkinos directory uses a single thread. You will only be able to use 1 module at a time! For full functionality, use a multithreaded web server like Apache or Nginx.
Learning Path for Penetration Testing Tools for Beginners
Phase 1: Understanding the Basics
Start with Karkinos’ encoding and hash generation features. These fundamental concepts appear in virtually every security assessment and provide excellent groundwork for more advanced techniques.
Phase 2: Reconnaissance Skills
Progress to the port scanning and directory busting modules. The first stage defines the goals and scope of the test and the testing methods that will be used, while security experts gather intelligence on the company’s system.
Phase 3: Active Testing
Advance to reverse shell handling and exploitation modules. This hands-on experience demonstrates how vulnerabilities can be leveraged in controlled environments.
Comparing Karkinos to Other Penetration Testing Tools for Beginners
While tools like Metasploit, Burp Suite, and Nmap remain industry standards, they can overwhelm newcomers. Karkinos bridges the gap by offering:
- Simplified Interface: Web-based operation eliminates complex installation procedures
- Educational Focus: Built specifically for learning rather than professional assessment
- Cost-Effective: Open-source alternative to expensive commercial platforms
- Integrated Environment: Multiple tools in one platform reduce setup complexity
