An HTTP brute force attack is a type of cyber attack where an automated program, called a brute force tool, attempts to guess a valid username and password combination for a login page using a trial-and-error method.
The attack typically starts by identifying the target website and its login page. The brute force tool then generates a list of possible username and password combinations, usually using a dictionary or password list, and tries each one by submitting them to the login page.
If a correct username and password combination is found, the attacker gains access to the targeted system or account. The attack may continue until the tool exhausts all possible combinations or reaches a predefined limit.
Such attacks can be prevented by implementing strong password policies, multi-factor authentication, rate limiting, and other security measures.
