What type of attack is characterized by the use of a predefined list of passwords?

A dictionary attack is characterized by the use of a predefined list of passwords, which typically includes common words, phrases, or variations. This method relies on the assumption that many users choose passwords that are simple, predictable, or based on common words found in the dictionary, hence the name "dictionary" attack.

In this type of attack, an attacker systematically attempts to log in to a system or service by trying each password from the list until the correct one is found. This is more efficient than a brute force attack, which tests all possible combinations of characters, as dictionary attacks can exploit the weaknesses in password choices made by users.

Brute force attacks involve attempting all combinations of characters, making them time-consuming and less efficient compared to the focused approach of a dictionary attack. Phishing attacks involve tricking users into revealing sensitive information, while man-in-the-middle attacks involve intercepting communications between two parties without their knowledge. Neither of these methods relies on a predefined list of passwords.
