What is the Cupp Tool?

Cupp (Common User Passwords Profiler) is a password-cracking tool designed to leverage personal information to predict potential password combinations. Whether you're a cybersecurity professional or a hacker, Cupp can aid in devising targeted password lists tailored to specific individuals.

Getting Started with Cupp

System Requirements

Before diving in, ensure you have a Debian-based Linux system (like Ubuntu) and that Python 3 is installed. You can check Python's installation by running:

python3 --version

This command will display the version of Python 3 if it is installed.

Installing the Cupp Tool

To install Cupp on your system, open your terminal and run:

sudo apt install cupp

sudo: Runs the command with superuser privileges.
apt: The package manager for Debian-based systems.
install: Installs the specified software package.
cupp: The name of the package you are installing.

If you have issues, you can also clone it from the Git repository:

git clone https://github.com/Mebus/cupp.git

git clone: This command copies the Cupp repository from GitHub to your local machine.

Navigating to the Cupp Directory

After installation, navigate to the directory where Cupp is located:

cd cupp

cd: Changes the directory to the specified path, which in this case is the Cupp folder.

Running the Cupp Tool

Executing Cupp

To run the Cupp tool, you’ll need to execute it using Python 3. You can do this by entering the following command:

python3 cupp.py

python3: Calls the Python 3 interpreter.
cupp.py: This is the main script for the Cupp tool that you want to execute.

Entering Interactive Mode

Cupp will guide you through the process. By default, it will start in interactive mode, where you’ll be prompted to provide personal information to generate password lists. You can include:

• Name
• Birth date
• Favorite color
• Company name

Customization in Interactive Mode

The interactive mode allows for the generation of highly personalized password lists based on the information you provide. Additionally, you can add other words or phrases to enhance the list further.

Enhancing Password Security

To create more complex password lists, you should consider including special characters and numbers. In the interactive mode, you will be asked whether you want to include these features. The Elite mode can also be activated for adding leet speak variations to your passwords, making them harder to crack.

Using Command Line Tools to Create Password Lists

After generating your personalized lists, you may want to compile or review them. Here’s how to use command line tools to manage the lists:

View Files

Use the ls command to check your current directory for any files:

ls

Lists all files and directories in the current working directory.

Create a New Text File

If you'd like to start a new password list, use:

touch my_password_list.txt

Creates a new text file named my_password_list.txt.

Editing the File

You can edit this file with a text editor, like nano:

nano my_password_list.txt

To save and exit, press Ctrl + X, then Y, and hit Enter.

Downloading Common Password Lists

If you prefer to utilize existing lists rather than creating your own from scratch, you can quickly download common password lists using a specific command, such as:

hype l

This command fetches password lists from the CPP repository.

Once downloaded, you can extract the zip files with:

unzip downloaded_file.zip

Extracts the contents of the specified ZIP file.

Conclusion

The Cupp tool is an invaluable asset in the toolkit of anyone involved in cybersecurity or ethical hacking. By leveraging personal information to create tailored password lists, you can significantly enhance your password-cracking efforts. Remember to practice responsible and ethical usage of these skills, contributing positively to the cybersecurity landscape.
