Katoolin is a Bash script designed to simplify the installation of Kali Linux penetration testing tools on Debian-based distributions like Ubuntu. It automates adding Kali repositories to your system's APT sources, importing the necessary GPG keys, and providing an interactive menu for managing these repositories and tools.

Primarily used by security enthusiasts and pentesters who want Kali's extensive toolset without dual-booting or switching distros. After setup, users can run apt update and install tools like metasploit, nmap, or aircrack-ng directly.

The script modifies /etc/apt/sources.list.d/katoolin.list and handles key imports securely. However, it's unofficial and maintained on GitHub. Usage involves cloning the repo, making it executable, and running with sudo. It's interactive: select options to add/remove repos or bulk-install tools (use cautiously).

Ideal for learning ethical hacking on stable distros, but requires caution due to potential package conflicts.

Risks system breakage via repo conflicts, dependency issues, or unstable Kali packages on Debian/Ubuntu. Not officially supported; may fail on newer releases. Backup before use. Bulk install (option 3) can overwhelm system. Better alternatives: Docker Kali images or official Kali on VM.

git clone https://github.com/S-h-3-d/Katoolin3
cd Katoolin3
chmod +x katoolin3
sudo ./katoolin3
Then sudo apt update.

After adding repos, search/install individually: apt search kali- or apt install toolname. Type 0 to exit menus.

Developed by S-h-3-d on GitHub (2016+). Evolved from Katoolin1/2 to Katoolin3 with better repo handling and menus. Popular in pentesting communities but flagged for risks; forks exist for fixes.
