Comparative Study on Password Cracking Tools

Abstract: In this paper, it provides a brief description about the different password cracking tools. Passwords are the most standard ways to protect and authenticate the security of a network or for any other information. Security of server in all contexts is dominating in every field of computing, while working on the servers numerous threats and attacks like cracking of passwords, knowing the root of machine, giving privilege to unauthorized users are common attacks that can harm the system and take access of servers. Password cracking is the process of obtaining the correct password to an account in an unauthorized way. The most prevalent commands like Hydra and Medusa, Ncrack, Patator are there which can be used for cracking the passwords of servers and unauthorized users can take access of server by applying these commands. Hydra is a login cracker which supports many protocols to attack. It works by different approaches to perform brute-force attacks in order to guess the right username and password combination. Medusa is a modular, speedy, and parallel, login brute-forcer. It is a very powerful and lightweight tool. The goal is to support as many services which allow remote authentication as possible. Ncrack is a very fast network authentication cracking tool that helps organization to secure their networks against password attacks. Patator is a security tool to perform enumeration or brute-force attempts to discover authentication details. It can be used during penetration testing. Penetration testing is a series of activities undertaken to identify and exploit security vulnerabilities. Here, we will consider brute force attack and its tools with its implementation and prevention ways or techniques to avoid these types of attacks
