CUPP (Common User Passwords Profiler) is a Python-based tool designed to generate targeted password wordlists based on personal information—commonly used in security awareness training and ethical penetration testing.

Basic Usage

Start by invoking the tool with its interactive mode:

python3 cupp.py -i

This launches a guided prompt where you provide cnotextual details such as:

• Target’s full name and nicknames
• Known birthdays, pet names, or hobbies
• Favorite sports teams, brands, or phrases
• Common leet-speak substitutions (e.g., 'a' → '@', 'o' → '0')

Once all inputs are submitted, CUPP processes permutations and writes the resulting combinations to a text file—e.g., xiao.txt.

Inspecting Output

To verify contents or review generated candidates:

cat xiao.txt

A typical run may produce tens of thousands of variations—54,818 entries, for instance—depending on input breadth and enabled mutation rules.

Ethical & Legal Considerations

This tool is intended strictly for authorized security education, red team exercises, and password policy validation. Its use against systems or accounts without explicit written consent violates global cybersecurity laws—including the Computer Fraud and Abuse Act (CFAA) and GDPR provisions on unauthorized access.

Always ensure compliance with organizational policies and applicable regulations before deploying any credential-auditing utility.
