Detailed explanation-1: -Brute-force attacks are carried out by hackers who try to crack a password by simply trying out different combinations of characters in quick succession. The algorithm is very simple and is limited to trying out as many character combinations as possible, which is why it is also called “exhaustive search".
Detailed explanation-2: -A brute force attack involves ‘guessing’ username and passwords to gain unauthorized access to a system. Brute force is a simple attack method and has a high success rate. Some attackers use applications and scripts as brute force tools.
Detailed explanation-3: -It can automatically detect the type of hashing used in a password. Therefore, you can also run it against encrypted password storage. Basically, it can perform brute force attacks with all possible passwords by combining text and numbers.
Detailed explanation-4: -Computer programs used for brute force attacks can check anywhere from 10, 000 to 1 billion passwords per second. There are 94 numbers, letters, and symbols on a standard keyboard. In total, they can generate around two hundred billion 8-character passwords.
Detailed explanation-5: -Explanation: A brute force is the simplest process of gaining access to any password-protected system. It tries a variety of combinations of usernames & passwords again and again until it cracks it or password matches.
