    [+] Summary : A Python-based scanner imitates CloudBleed-style leakage detection by fetching raw HTTP response data from a target website, converting it to hexadecimal, 
                 and searching for sensitive memory patterns such as sessions, passwords, tokens, cookies, AWS keys, and stack traces. 
    			 It does not exploit the server, but identifies potential leaks revealed in the response body.
