Which password cracking technique works like a dictionary attack but adds some numbers and symbols to words from the dictionary?

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

Answer: (B)

Starting with a dictionary of common words and then mutating those words by adding numbers and symbols mirrors how many real passwords are created: a familiar word kept for memorability, with simple alterations to make it harder to guess. This approach blends the efficiency of a dictionary attack with a small, targeted brute-force-like step, introducing digits and punctuation to the base words. That combination is what defines a hybrid attack: it uses dictionary words as a foundation and applies mutations that include numbers and symbols, expanding the guess space in a realistic way without trying every possible character sequence. Brute-forcing would try all possible characters from scratch, which is far more exhaustive and impractical for longer passwords. Syllable-based attacks build passwords from pronounceable chunks rather than full dictionary words, and rule-based attacks systematically apply transformation rules to dictionary words but aren’t specifically defined by adding numbers and symbols in the way a hybrid approach is. The hybrid approach uniquely fits the description of dictionary words plus numerical and symbolic modifications.
