Question

Davian, a professional hacker, tries every possible combination of characters to crack his victim's email password. Using this technique, he can crack a six-character password of either upper- or lowercase letters in about five minutes. Which of the following techniques is used by Davian to obtain access to his victim's email?

A) denial-of-service attack
B) brute force attack
C) pretexting
D) spoofing

Answer 1

B) brute force attack

Step-by-step explanation:

A brute force attack is a method used by hackers, like Davian, to crack passwords or encryption keys by trying all possible combinations of characters until the correct one is found. In this scenario, Davian is using a brute force attack to guess the victim's email password by trying every possible combination of characters in a six-character password. This technique allows him to gain access to the victim's email account in about five minutes if the password consists of either upper or lowercase letters.

Answer 2

Davian uses a brute force attack to crack passwords by trying every possible combination of characters until the correct one is found.

Step-by-step explanation:

The technique used by Davian, the professional hacker, to obtain access to his victim's email by trying every possible combination of characters is known as a brute force attack. This approach involves systematically checking all possible combinations until the correct one is found, which can be effective but requires significant computational power and time for complex passwords.
