I have always wondered how exactly a brute force attack works. I understand, that there is an algorithm, that tries out every password combination over and over until it finds a hit. Now with simple passwords and fast processors this seems like an easy task.
What I don't understand, is how the server allows this. Let's say you don't use a Login Captcha. Even then the server should be able to identify these attacks easily. Either bc someone is trying to log in into the same account over and over again or due to the IP Address. Even if you change your IP Address and Account every time, can the server not just delay the response to limit the amount of attempts?
Or is it, that Brut Force attacks only work on very unprotected servers ?
