- `colorama` - Used for adding color and style to the text printed in the terminal.
- `ipaddress` - Used for validating IPv4 addresses.
- `platform` - Used to detect the operating system.
- `subprocess` - Used for spawning new processes.
- `ctypes` - Used to interact with the Windows API, specifically for checking and requesting administrator privileges.
- `sys` - Used to interact with the interpreter to exit the program.
- `time` - Adds a delay of 2 seconds when exiting the script.

Features

• Multi-OS Support: Compatible with Linux, macOS, and Windows.
• Interactive CLI: User-friendly command line interface for ease of use.
• Dynamic Payload Generation: Supports multiple types of reverse shells.
• Listener Automation: Simplifies the process of setting up listeners with netcat/ncat.

Configuration

The script has several library dependencies as shown above. Besides, you should configure it according to your operating system.

Linux

• rlwrap is not a built-in command in many Linux distros. Install it as follows:

1. Debian/Ubuntu-based systems:

sudo apt-get update
sudo apt-get install rlwrap

2. Red Hat-based systems (Fedora, CentOS, RHEL):

sudo dnf install rlwrap  # For Fedora
sudo yum install rlwrap  # For CentOS/RHEL

3. Arch Linux

sudo pacman -Sy rlwrap

4. openSUSE

sudo zypper install rlwrap

• DO NOT FORGET TO CHECK THE WHETHER YOU HAVE 'NETCAT' or not

which nc

Windows

• As you know Windows operating system does not support netcat directly. Therefore, we have another alternative for that. Ncat is a modern reimplementation of the classic Netcat (nc) tool. Shell-Bringer only supports that listener.

Using Nmap Installer:

1. Download Nmap for Windows:

   • Visit the official Nmap download page at https://nmap.org/download.html and download the Windows installer.

2. Run the Installer:

   • Run the downloaded Nmap installer (.exe file) and follow the on-screen instructions.

3. Select Components:

   • During the installation process, ensure that you select the option to install Ncat along with Nmap. The installer usually provides checkboxes for components like Ncat, Zenmap, etc.

4. Complete Installation:

   • Complete the installation by following the prompts. Once done, Ncat will be installed on your system.

Using Chocolatey (Package Manager for Windows)

1. Install Chocolatey (if not already installed):

   • Open an elevated Command Prompt (run as administrator) and run the following command:

     @"%SystemRoot%\System32\WindowsPowerShell\v1.0\powershell.exe" -NoProfile -InputFormat None -ExecutionPolicy Bypass -Command "iex ((New-Object System.Net.WebClient).DownloadString('https://chocolatey.org/install.ps1'))" && SET "PATH=%PATH%;%ALLUSERSPROFILE%\chocolatey\bin"

2. Install Nmap (including Ncat) via Chocolatey:

   • After Chocolatey is installed, you can install Nmap with the following command:

     choco install nmap

3. Verify Installation:

   • After installation, verify that Nmap and Ncat are installed by running the following commands in Command Prompt or PowerShell:

     nmap --version

     ncat --version

MacOS

1. Install Homebrew (if not already installed):

   • Open Terminal and run the following command to install Homebrew:

     /bin/bash -c "$(curl -fsSL https://raw.githubusercontent.com/Homebrew/install/HEAD/install.sh)"

2. Install Nmap (includes Ncat) using Homebrew:

   • Once Homebrew is installed, you can install Nmap, which includes Ncat, by running:

     brew install nmap

3. Verify Installation:

   • After installation is complete, you can verify that Nmap and Ncat are installed by running:

     nmap --version

     ncat --version
