Security Fundamentals — Question 31

Which type of password attack attempts to guess passwords by using a list of common passwords?

Answer options

• A. Keylogger
• B. brute force
• C. man-in-the-middle
• D. dictionary

Correct answer: D

Explanation

The correct answer is D, dictionary, as it specifically refers to the method of using a predefined list of common passwords to find the right one. Option A, keylogger, records keystrokes to capture passwords rather than guessing them. Option B, brute force, involves trying every possible combination rather than just common ones. Option C, man-in-the-middle, is an attack that intercepts communication, not a password guessing technique.
