Computer Hacking Forensic Investigator (CHFI) — Question 23

Which password cracking technique uses details such as length of password, character sets used to construct the password, etc.?

Answer options

• A. Dictionary attack
• B. Brute force attack
• C. Rule-based attack
• D. Man in the middle attack

Correct answer: A

Explanation

The correct answer is A, Dictionary attack, because it specifically uses known words and patterns in various combinations to crack passwords. In contrast, a Brute force attack systematically tries every possible combination without regard to patterns, while a Rule-based attack applies specific rules to modify existing passwords. The Man in the middle attack is unrelated as it involves intercepting communications rather than cracking passwords.
