The attacker is performing a dictionary attack, where they use a dictionary file containing known words or passwords as input to crack the passwords in the password file. A brute force attack would involve trying every possible combination of characters to guess the password, while a replay attack involves intercepting and reusing valid authentication credentials. A ciphertext-only attack attempts to decrypt ciphertext without any knowledge of the encryption algorithm or key.
