CrackJack

CrackJack is a Python tool designed to perform brute-force attacks on web application login pages. It iterates through a list of usernames and passwords, attempting to find valid credentials. The tool includes rate-limiting to prevent overwhelming the server with requests.

Features

• Brute-Force Attack: Tests multiple username and password combinations to find valid credentials.
• Rate Limiting: Limits the number of requests sent per second to avoid detection and server overload.
• Exception Handling: Handles common errors gracefully, including network issues and invalid responses.
• Input Validation: Ensures that provided inputs, such as URL and credential lists, are valid.
• URL Validation: Checks if the provided URL is in a valid format before attempting login.

Parameters

• -u <url>: The URL of the login page to attack.
• -u_file <usernames_file>: File containing a list of usernames (one per line).
