Hydra is a brute force password cracking tool. In information security (IT security), password cracking is the methodology of guessing passwords from databases that have been stored in or are in transit within a computer system or network. A common approach and the approach used by Hydra and many other similar pentesting tools and programs are referred to as Brute Force. We could easily do a Concise Bytes on ‘Brute Force Hacking’ but since this post is all about Hydra let’s place the brute-force attack concept within this password-guessing tool. Brute force just means that the program launches a relentless barrage of passwords at a login to guess the password. As we know, the majority of users have weak passwords and all too often they are easily guessed.

A little bit of social engineering and the chances of finding the correct password for a user are multiplied. Most people (especially those non-IT savvy, will base their ‘secret’ passwords on words and nouns that they will not easily forget. These words are common: loved ones, children’s names, street addresses, favorite football team, place of birth etc.

Brute force will take the list that the hacker built and will likely combine it with other known (easy passwords, such as ‘password1, password2’ etc) and begin the attack.

Depending on the processing speed of the hackers (auditors) computer, Internet connection (and perhaps proxies) the brute force methodology will systematically go through each password until the correct one is discovered. It is not considered as being very subtle – but hey it works! Hydra is considered as being one of the better ones out there and it certainly worth your time as a security professional or student to give it a try. Resources and tutorials The majority of pentesting/ hacking tools are created and developed from a security perspective, meaning that they are designed to aid the pentester find flaws in their clients systems and take appropriate action. Hydra works by helping the auditor find weak passwords in their clients network.

According to the Hydra developers they recommend that the professional do the following when using Hydra: Step 1: Make your network as secure as possible. Step 2: Set up a test network Step 3: Set up a test server Step 4: Configure services Step 5: Configure the ACL Step 6: Choose good passwords Step 7: Use SSL Step 8: Use Cryptography Step 9: Use an IDS Step 10: Throw Hydra against the security and try and crack the logon commands.

The below commands will install Hydra and here is our favorite video tutorial on how to use Hydra. How do we defend against Hydra and brute force attacks? There are several ways a system admin or network engineer can defend against brute force attacks. Here are a few methods. If you can think of any others, or disagree with the below, let us know in the comment below! Disable or block access to accounts when a predetermined number of failed authentication attempts has been reached. Consider multi-factor or double opt-in/ log in for users.
