What are the types of password attack?

So now as we know what a password actually is,its time to discuss the common methods of cracking a password.The three most common of them are Dictionary attack,Brute force attack and Hybrid attack.
A brief description of each will help us understand these methods hindering tech security.


1. Dictionary Attack : In this an attacker tries to use the entire password prewritten in separate files called a  dictionary which contains common passwords used by people and English dictionary words.This is the least time consuming method but the success rate here is very poor.


2. Brute Force Attack : This attack can have a success rate upto 100% at times because here an attacker tries to use permutation and combinations possible by a set of character sets such as 0-9, A-Z, a-z and symbols.However in case of a lengthy password this method becomes very slow hence making it almost unfeasible.


3. Hybrid Attack : Hybrid attack is where an attacker uses the combination of the above mentioned  methods or any other method. Hybrid attack also involve pre computed tables of hashes which increases the speed and tables are generated by using all the character sets thereby increasing the success rate.
