Computer Hacking Forensic Investigator (CHFI v10) — Question 338

Jacky encrypts her documents using a password. It is known that she uses her daughter's year of birth as part of the password. Which password cracking technique would be optimal to crack her password?

Answer options

• A. Rule-based attack
• B. Brute force attack
• C. Syllable attack
• D. Hybrid attack

Correct answer: A

Explanation

The optimal technique in this scenario is a Rule-based attack because it exploits known patterns or information, such as the inclusion of a specific year in a password. Other methods like Brute force attack would take significantly longer as they try every possible combination, while Syllable and Hybrid attacks are less targeted and therefore not as efficient in this context.
