Later use this dictionary under burp suite through intruder as payload for brute force attack. In order to use dictionary as payload click on payload tab under intruder; now load your dictionary which contains user password names from payload options. But we want to send request in encoded value of our payload.
To encode your payload click on ADD button available under payload processing A new dialog box will generate to select the rule choose encode option from list; now select base 64 from drag down list of URL encode key character for payload processing. This will start brute force attack and try to match string for user authentication.
In screenshot you can the status and length of the highlighted value is different from rest of values. This means we can use this encoded value to bypass the user authentication which occur from request number 6. Now check the username and password of 6 th line in dictionary.
Now again open the router IP and this time type the above username and password. From screenshot you can see I have successfully login in control panel of router. Attacker: Kali Linux. Target: TP link Router. In this article I will perform an attack on router and try to bypass its authentication. To carry out a brute force attack, we will be using the intruder feature in Burpsuite.
Some of the things required for this attack are a list of common usernames and passwords. This will send the request information to the intruder. Go to the intruder tab. Now we will have to configure Burpsuite to launch the brute force attack. Under the target tab, we can see that it has already set the target by looking at the request. Go to the positions tab now, here we can see the request which we had previously sent to intruder.
Some of the things are highlighted in the request. This is basically a guess by Burpsuite to figure out what all things will be changing with each request in a Brute force attack.
Since in this case only username and password will be changing with each request, we need to configure Burp accordingly. Click on the clear button on the right hand side. This will remove all the highlighted text, now we need to configure Burp to only set the username and password as the parameters for this attack. Similarly, highlight the password from this request and click on Add. This will add the username and password as the first and second parameters.
Once you are done, your output should look something like this. The next thing we need to do is set the Attack type for this attack, which is found at the top of the request we just modified.
By default it is set to Sniper. Basically the idea of cluster bomb is to use Multiple payload sets 1 for username and 1 for the password. The attack will start by trying all the values in Payload 1 with first value in Payload 2, then by trying all the values in Payload 1 with second value in Payload 2 and so on.
Go to the payload tab, make sure payload set 1 is selected, click on load and load the file containing a list of usernames. In my case I am using a very small file just for demonstrations purposes. Once you load the file all the usernames will be displayed as shown in the image below. All right we are now set to launch our attack. We will see a windows pop up with all the requests being made.
So how do we know which request is successful? Usually a successful request will have a different response than an unsuccessful request or will have a different status response. In this article we discussed some of the common authentication methods used, the vulnerabilities in these authentication methods and then looked at different ways to attack them. However, this is just a part of the story. We will be discussing all these in the next article.
A new tab for your requested boot camp pricing will open in 5 seconds. If it doesn't open, click here. He is currently a researcher for InfoSec Institute. In the past he has worked for security-based startups. You can contact him at prateek. Plz show me how to start Burpsuite in backtrack 5…KDE version… and this is nice website.. Your email address will not be published. Topics Hacking Hacking web authentication — part one Hacking Hacking web authentication — part one. But we want to send a request in the encoded value of our payload.
To encode your payload click on ADD button available under payload processing. A new dialog box will generate to select the rule to choose an encode option from the list; now select base64 from drag down the list of URL encode key character for payload processing. This will start a brute force attack and try to match string for user authentication.
This means we can use this encoded value to bypass the user authentication, which occurs from request number 5. Now check the username and password on the 5th line in the dictionary.
In the dictionary I found raj: have matching authentication. Or you can also use this encoded Auth value to bypass the Apache HTTP authentication page via burp suite intercepted data. Copy the above auth value and paste replace it with intercepted authorization a shown in below and forward the request to access restricted content. Here we have successfully access the content of the website. Hope you people have enjoyed this article and learned how weak configuration security can easily breach and the unauthorized person can access the restrict content of your website.

I have configured everything as mention in the article and it is working properly without any error. Skip to content Hacking Articles. Penetration Testing. December 21, by Raj Chandel.

I will be accessible with a username and password prompt that looks like this: If you will try to access the website without authentication or canceled the Required Authentication page then it will displace error Unauthorized Access. For this method to work: Open xHydra in your Kali. Hydra Hydra is often the tool of choice.
Run the following command hydra -L user. Ncrack Ncrack is a high-speed network authentication cracking tool. Run the following command ncrack -U user. Medusa Medusa is intended to be a speedy, massively parallel, modular, login brute-forcer.
