Computer Hacking Forensic Investigator (CHFI v10) — Question 548

Which type of attack is possible when attackers know some credible information about the victim's password, such as the password length, algorithms involved, or the strings and characters used in its creation?

Answer options

• A. Rule-Based Attack
• B. Brute-Forcing Attack
• C. Dictionary Attack
• D. Hybrid Password Guessing Attack

Correct answer: A

Explanation

A Rule-Based Attack utilizes known information about the password to create targeted guesses, making it more efficient than random attempts. In contrast, a Brute-Forcing Attack tries every possible combination without leveraging any knowledge, while a Dictionary Attack uses a predefined list of common passwords. A Hybrid Password Guessing Attack combines elements of both dictionary and brute-force methods but does not specifically focus on the established rules based on credible information like a Rule-Based Attack does.
