How does CUPP Tool Works?

The working of the CUPP Tool is quite simple. It would help if you executed the python script using the following command.

python3 cupp.py

After running the script, you need to choose the appropriate tag for the flag or creating the wordlists. For Example, if you have selected the -i tag, the CUPP tool interacts with you and asks you some common questions about your target domain or person. You need to answer those questions, and if you are not too familiar or don’t know the answer, you can skip the question about pressing the Enter Button on the keyboard. After providing all the solutions, your work is done; now, the CUPP tool will analyze the input and design unique words or password words. After analyzing the responses, the CUPP tool generates a text file containing the phrase that attackers can use to brute force or use as Username or Password wordlist to perform password cracking attacks against that victim.

Usernames and Password values are the most commonly used methods for authentication purposes in almost every web application or any type of application. When the credentials provided in this type match the values stored at the server, only the user is authenticated to the specified service. Using weak Usernames and Passwords may lead to various impactful cyber threats like Password Cracking, Brute-Forcing, and Account Takeover.  CUPP tool is an automated script written in the python language that interacts with the user and answers some fundamental questions about the victim like Name, Company Name, Partner’s Name, etc. After analyzing these answers, the CUPP tool generates some possible Usernames+Password words that attackers can use for various attacks like Password Cracking and Brute-Forcing.
