Burp Intruder
The burp intruder is a feature in burpsuite which helps to perform extensive fuzz testing. It helps us to enumerate varaious parameters in a request with supplied wordlist. From password bruteforcing to XSS testing, we can perform all kinds of fuzzing using this amazing plugin in burpsuite.
How Intruder works ?
In order to get started with intruder, we need to get the request captured. This can be a GET or POST request depending on the web-application. Once the rwquest is captured, it can be sent to intruder. Then intruder analyses variable positions in the request where a payload can be inserted. The payload is simply a wordlist we supply. After the wordlist is supplied, the intruder can run through all the combinations in the wordlist on the positions set.
The Payloads tab is where you set the wordlist or list of variables to be run against the payload positions we set previously. There are numerous possibilities & combinations you can try here. You can load a list containing all the words or strings, or you can generate words based on the characters you supply etc. It can be specified in the Payload type drop down menu. Try browsing trhough all of them and you will understand the power of Intruder. For now we supply a simple list. Select the payload type as simple list & click the load button to open an explorer window. Select your wordlist that contains passwords. In Kali, sme default wordlists are supplied inside “/usr/share/wordlists/”. For this one I have selected, “/usr/share/wordlists/metasploit-jtr/password.lst”.
