A brute-force attack is a method used in information security to crack passwords or encryptions. In this method, the attacker systematically tries all possible combinations of characters, numbers, and symbols to guess the desired password or encryption.
While this method is time-consuming, if the length and complexity of the password or encryption are not sufficiently high, a brute-force attack can be successful. To mitigate the effectiveness of such attacks, systems often employ measures such as limiting the number of attempts or implementing two-factor authentication.
