What is a common method used in brute-force attacks?

Brute-force attacks are methods used to gain unauthorized access by systematically attempting all possible combinations of passwords or encryption keys until the correct one is found. Password cracking is a direct application of this method, where an attacker attempts to guess a user's password by trying numerous combinations until successful.

In this context, password cracking aligns perfectly with the definition of a brute-force attack, as it operates on the principle of brute-force methodology. The goal is to breach security measures by using computational power to automate the guessing process.

The other options do not pertain to the brute-force method. Data encryption is a process used to secure data rather than break it. Website spoofing involves mimicking a legitimate website to deceive users and steal their information, while SQL Injection is a type of attack that targets database queries and is not related to brute-force techniques. Therefore, password cracking unequivocally represents a common method associated with brute-force attacks.
