How would you describe a "brute force" attack?

A "brute force" attack is characterized by its methodical approach to breaking passwords by attempting every possible combination until the correct one is found. This technique relies on computational power and time rather than specific knowledge about the target, making it a direct and exhaustive way of cracking passwords. It does not discriminate based on common words or phrases, and it is purely focused on exhaustively trying all potential combinations, which is why option B accurately captures the essence of what a brute force attack entails.

In contrast, the other choices describe different types of attack strategies. For instance, the quick method of guessing passwords using common words refers to dictionary attacks, which save time by only trying words that are likely to be used as passwords. The mention of malware relates to a different category of cyber threats that involves compromising systems through malicious software. Lastly, bypassing existing security measures can encompass various tactics but does not specifically define the exhaustive and systematic nature of how brute force attacks operate. Each of these aspects highlights different methodologies in cybersecurity, distinct from the brute force approach.
