Answer 1

A dictionary attack employs a list of pre-defined passwords that it tries against a login prompt. It is a common method used by hackers to gain unauthorized access to user accounts.

Step-by-step explanation:

A dictionary attack employs a list of pre-defined passwords that it tries against a login prompt. It is a common method used by hackers to gain unauthorized access to user accounts.

During a dictionary attack, the attacker uses a dictionary file containing commonly used passwords, personal information, or real words as potential passwords. The attack process involves systematically trying each password from the dictionary file until a correct one is found or the entire list has been exhausted.

For example, if the attacker has a dictionary file that includes passwords like 'password,' '123456,' and 'qwerty,' the attack script would try each of these passwords one by one until it successfully logs into the targeted account.
