In Kali, sme default wordlists are supplied inside “/usr/share/wordlists/”. Select your wordlist that contains passwords. Select the payload type as simple list & click the load button to open an explorer window. Try browsing trhough all of them and you will understand the power of Intruder. It can be specified in the Payload type drop down menu. You can load a list containing all the words or strings, or you can generate words based on the characters you supply etc. There are numerous possibilities & combinations you can try here. The Payloads tab is where you set the wordlist or list of variables to be run against the payload positions we set previously. Speaking of payload, keep reading, it will be explained in the next para so move on to the Payloads tab. If you have multiple positions, it will fire the payload at the first position and then move on to the second and so on.(One at a time). It fires the payload precisely at a single point. This attack type works just like sniper gun. Once the position is set, confirm whether the Attack type is Sinper. Just like closing brackets in programing or in Maths make sure to open a position and close it. Add a position there also otherwise the whole content after the position will be taken as a single position. Then go to the last letter of that feild and place the cursor there. First keep the cursor just after the “=” and click add. It’s seen at the bottom of the whole request. In this case, clear all positions & add position in the password variable. You can customize it by using the options in the Right side of the tab. Burp will automatically populate all positions where a fuzz test can be run. This is where we set the variables to be attacked/fuzzed. Just cross verify whether the target you are attacking is displayed correctly in this section and proceed to next Intruder – Host Options This page/tab contains target options like host port use SSL etc. Then, you will be shown the Intruder options and first target will be shown. Capturing POST Request Step 4: Send it to Intruder & Configure OptionsĬlick on the Action button in the top right and select send to intruder. Anyway the idea is we need to capture a request in which some variable value is supplied to the server. This can occasionally be a GET request also. Opening the Target Pageįorwarding the Request Step 3: Capture the POST requestĬapture the POST request where the username & password is supplied to the web-application. Step 2: Capture the requestĪfter you have configured burp, start intercepting & open the target page. If you are not clear on this, refere to Getting Started with Burpsuite article. Step 1: Setup Burp as Intercepting Proxyįor this you need to setup the burp as proxy first. This tutorial shows performing this on mutillidae. In this, lab a simple brute-force against a password is performed. Target URL: 10.0.2.4/mutillidae/index.php/page=login.php Target : OWASP-BWA – Mutillidae – IP=10.0.2.4 Mutillidae download link is given at the end of the tutorial. Lab Setupįor this tutorial I am using Mutillidae as the target, Burpsuite running on Kali as attacker. After the wordlist is supplied, the intruder can run through all the combinations in the wordlist on the positions set. The payload is simply a wordlist we supply. Then intruder analyses variable positions in the request where a payload can be inserted. Once the rwquest is captured, it can be sent to intruder. This can be a GET or POST request depending on the web-application. In order to get started with intruder, we need to get the request captured. From password bruteforcing to XSS testing, we can perform all kinds of fuzzing using this amazing plugin in burpsuite. It helps us to enumerate varaious parameters in a request with supplied wordlist. The burp intruder is a feature in burpsuite which helps to perform extensive fuzz testing. For those who are new to burpsuite, read this article on Getting started with Burpsuite. In this article, we will see how to use burp intruder to bruteforce inputs in a web application. So even HTTPS connections passing through burpsuite are visible. But the prime feature is that, it is an intercepting proxy which works on application layer. It contains about 8 useful tools for performing spidering, fuzzing, decoding etc. Using Burp Intruder to Bruteforce passwords.īurpsuite is a collection of tools and plugins for any web application security testing bundled into a single executable jar file.
