What is Karkinos?

Karkinos is a light-weight ‘Swiss Army Knife’ for penetration testing and/or hacking CTF’s. Currently, Karkinos offers the following:

  • Encoding/Decoding characters
  • Encrypting/Decrypting text or files
  • Reverse shell handling
  • Cracking and generating hashes

Disclaimer

Use this tool to make penetration tests or any hacking CTF’s more efficient. This tool should be used on applications that you have permission to attack only. Any misuse or damage caused will be solely the users’ responsibility. Please check the known bugs and issues at the bottom before installation.
A Wiki page for troubleshooting is coming very soon.

Dependencies

  • Any server capable of hosting PHP; tested with Apache Server
  • Tested with PHP 7.4.9
  • Python3
    Make sure it is in your path as:
    Windows: python
    Linux: python3
    If it is not, please change the commands in includes/pid.php
  • pip3
  • Raspberry Pi Zero friendly  (crack hashes at your own risk)

Installing

This installation guide assumes you have all the dependencies.

Linux/BSD

git clone https://github.com/helich0pper/Karkinos.git
cd Karkinos
pip3 install -r requirements.txt
cd wordlists && tar -xf passlist.zip

ou can also unzip it manually using file explorer if tar is not installed. Just make sure passlist.txt is in wordlists directory.

Add extension=php_sqlite3.dll to your php.ini file.
If you don’t know where to find this, refer to the PHP docs.

That’s it! Now just host it using your preferred web server or run: php -S 127.0.0.1:8888 in the Karkinos directory.
Important: using port 5555 will conflict with the reverse shell handler server
If you insist on using port 5555, change the reverse shell handler server PORT value in /bin/Server/app.py Line 87

Windows

git clone https://github.com/helich0pper/Karkinos.git
cd Karkinos
pip3 install -r requirements.txt
cd wordlists && tar -xf passlist.zip

Demo

Home Menu

Landing page and quick access menu.

User stats are displayed here. Currently, the stats recorded are only the total hashes and hash types cracked successfully.

Encoding/Decoding

This page allows you to encode/decode in common formats (more may be added soon)

Encrypt/Decrypt

Encrypting and decrypting text or files is made easy and is fully trusted since it is done locally.

Reverse Shell Handling

Reverse shells can be captured and interacted with on this page.

Create a listener instance

Generating Hashes

Karkinos can generate commonly used hashes such as:

  • MD5
  • SHA1
  • SHA256
  • SHA512

Cracking Hashes

Karkinos offers the option to simultaneously crack hashes using a built-in wordlist consisting of over 15 million common and breached passwords. This list can easily be modified and/or completely replaced.
