In a dictionary attack, what is the primary method used to crack passwords?

• A. Using brute-force techniques
• B. Employing a dictionary file with common passwords
• C. Consulting password recovery tools
• D. Using encrypted password hashes

Answer: (B)

In a dictionary attack, the primary method involves employing a dictionary file that contains a list of common passwords and phrases. This technique operates on the premise that many users select easily guessable passwords, often consisting of words found in the dictionary, phrases, or common sequences. The attacker systematically attempts each entry from this list against the target’s password until they find a match. This approach differs fundamentally from brute-force techniques, which attempt every possible combination of characters until the correct password is found, significantly increasing the time and resources needed for a successful attack. Similarly, consulting password recovery tools may assist in the recovery process, but they are not inherently focused on the specific methodology of a dictionary attack. Lastly, using encrypted password hashes does not directly correlate with the process of cracking passwords; rather, it is a representation of stored passwords that are often targeted in various attack scenarios. Thus, employing a dictionary file with common passwords is the hallmark strategy of a dictionary attack.
