Brute-force

A type of attack typically targeting authentication mechanisms such as password protection. A brute-force attack is an exhaustive, trial-and-error attempt that involves rapidly cycling through a comprehensive list of possible passwords or decryption keys, until the correct one is entered.

Often, a brute-force attack is combined with a dictionary attack, which uses a long list of words taken from dictionaries and popular culture references. Unlike a standard brute force attack, a dictionary attack uses words that are thought to be have the highest chances of success.

Brute-force attacks commonly succeed due to weak passwords and/or human error or laxness.
