Brute force attacks are designed to guess passwords by trying every possible combination of letters, numbers, and symbols until the correct password is discovered. In this case, the attacker is using a password-cracking program to attempt every possible combination of letters, making it a brute force attack. Replay attacks involve intercepting and reusing network traffic, ciphertext-only attacks involve attempting to decrypt ciphertext without any knowledge of the encryption algorithm or key, and dictionary attacks involve using a pre-existing list of commonly used passwords to attempt to guess the correct password.
