We see a GET request, at /dvwa/vulnerabilities/brute, with three parameters, the username, the password and a Login parameter set to Login, and a cookie with our session id (since we logged in in the first page of DVWA). Make sure that “Intercept is ON” in the proxy tab of Burp and then try a login attempt, so we can capture it in Burp: Then we need to tell our browser where is our proxy listening for requests.įor Firefox this setting is under Preferences -> Advanced -> Network -> Connection Settings: Just open Burp, and navigate to the Proxy tab.īy default it should be setup to listen to requests on 127.0.0.1:8080. Now, let’s see how a login attempt looks under the hood, at the level of HTTP.įor that we’ll use Burp as a proxy between our browser and DVWA. In our case the word that indicates a failed login attempt will be “incorrect”. We’ll start with collecting all the information that we need for the attack and then we’ll configure hydra and brute-force the login page.įirst, we’ll need to describe to hydra how a failed login attempt looks like, and that we’ll manage by making a failed attempt to login, and then grabbing a unique word from the error message: For that we’ll use THC Hydra, which is a tool that automates login attempts to almost any used protocol. It’s a Damn Vulnerable Web Application set to low security setting, so let’s just brute-force it. In the first login page of DVWA that you see, login with username “admin” and password “password” and then navigate to the “Brute Force” tab. Last time we setup DVWA on our Kali installation, so let’s start having fun with it!Īll the tools that we’ll use, come pre-installed in Kali. Brute-forcing HTTP login pages with Hydra
