So, now we have theВ informationВ we need to attack this login form, we can use this info to construct a Hydra brute-force attack as follows:

If we put in one wrong username and password combination we get:Д«ad login, stop bruteforcing me!Bad u/p combination for user: a The important parts of the HTML form are: So looking at an example the w3af testing framework has a test login at the following location The Web Security Dojo VM has various vulnerable applications that you can use to test these techniques. Not knowing or understanding the above information can be a big cause of failure.ДЇor the parameters of the request, you can intercept and examine a normal login attempt with a web proxy (such as owasp-zap, webscarab or burpsuite) or use a browser plugin (such as tamperdata) or just look at the HTML form.

What lockout features and thresholds are enabled (if any).Whether any session cookies are required to be set or maintained.The difference in response between success and failure.Whether the form supports GET or POST (or both).Every web-based form is slightly different, different URLs and parameters, and different responses for success or failure. This attack generally works very well for simple dictionary passwords.ДЇor web-based forms, you have to know much more information about the form you are attacking before you start the attack. This can take a while, so it is best to only use usernames you know exist, and a relatively small list of passwords (many thousands rather than many millions). This will attack the system 192.1.68.1.26, on port 22 with the SSH protocol, 10 threads at a time, and try all the combinations of usernames and passwords supplied in the files user.txt and pass.txt (+ empty passwords and passwords the same as the username) Here is a simple example of running a Hydra attack against an SSH server.

Online attacks are more suited to relatively small and focused dictionary attacks rather than exhaustive brute-force. With online password attacks there are more issues to consider, such as network bandwidth, account lockouts, tar-pitting, changing passwords, detection in logs and IDS. The attack success is purely dependent on password strength, verses processor-power and time (and few user-chosen passwords will be strong enough to last). You have as long as you want, and you can try many billions of attempts in a short space of time. With off-line cracking, you have the hashes on your system, they are static, and you can try dictionary, hybrid, and brute force attacks to you hearts content. There are significant differences between online and off-line password cracking. Some differences between online and off-line password cracking Use this for legitimate testing purposes only. This tool should not be used to attack websites or services where you do not have permission to do so.

This attack is not limited to websites, and I would argue that it is more suited for gaining login access to software products that have a web UI, for example in penetration tests.

I have had a great deal of success with hydra, so here I describe how to get Hydra working with web-based form logins. Often, web-based login forms authenticate using the HTTP POST method, but judging from several blogs I have read on this subject, it sounds like some people have great difficulty in getting Hydra to work effectively in this situation. (Hydra is to online-cracking of passwords, what John The Ripper is to offline-cracking of password hashes) Hydra can be used to attack many different services including IMAP, SMB, HTTP, VNC, MS-SQL MySQL, SMTP, SSH, and many more.
