. Attackers take a list of potential passwords, hash them, and see if the resulting string matches the stolen hash. Because NTLM hashes are
import hashlib def crack_ntlm(target_hash, wordlist_path): with open(wordlist_path, 'r', encoding='utf-8', errors='ignore') as f: for word in f: word = word.strip() # NTLM uses MD4 of the UTF-16LE encoded password hash_attempt = hashlib.new('md4', word.encode('utf-16le')).hexdigest() if hash_attempt.lower() == target_hash.lower(): return f"Success! Password is: word" return "Password not found in list." # Example usage # target = "31d6cfe0d16ae931b73c59d7e0c089c0" # Hash for empty string # print(crack_ntlm(target, 'passwords.txt')) Use code with caution.

These are massive, pre-computed tables of hashes and their corresponding plaintext passwords. Instead of calculating the hash on the fly, the tool simply looks up the NTLM hash in the table to find the match instantly. 4. GPU-Accelerated Cracking Password is: word" return "Password not found in list
