Brute-force attack

A brute-force attack is like a game of guessing. To do a brute-force attack, a person would try to guess the answer to something over and over until they get it right. For example, if they were trying to guess a secret password, they would guess different words and combinations of words until they get the correct one. It can be very time consuming, but eventually they will guess the right answer.
