4 days ago · When you send a request to Burp Intruder, a new tab is created containing the request and target details. You can set payload positions anywhere in these fields. These positions determine where Burp Intruder will insert payloads during the attack.

- Step 3: Set The Payload Position
- Step 4: Select An Attack Type
- Step 5: Add The Payloads

Open Burp's browser, and use it to access the following URL: Click Access the laband log in to your PortSwigger account if prompted. This opens your own instance of a deliberately vulnerable blog website.
Click My account, then try to log in using an invalid username and password. In Burp Suite, go to the Proxy > HTTP historytab. This shows the requests you have made in Burp's browser since opening it. Find the POST /login request. Highlight the value of the username parameter, then right-click the request and select Send to Intruder.
Go to Intruder. Observe that there is now a tab displaying the POST /loginrequest. We'll use this as the base request for our attack. Notice that the value of the usernameparameter that you previously highlighted is now marked as a payload position. This is indicated by the § characters at the beginning and end of the value. Burp Intruder will inse...
At the top of the screen, you can select different attack types. For now, just make sure this is set to Sniper attack. A Sniper attackinserts a single set of payloads, one by one, into one or more positions within the request.
You now just need to configure the list of payloads that you want to use. For this demonstration, we'll try sending the request with different usernames to test how the login mechanism behaves. Copy the following list of candidate usernames: 1. Candidate usernames In the Payloads side panel, leave the Payload type set to Simple list. In the Payload...
Click Start attack. This opens a new attack window in which you can see each of the requests that Burp Intruder is making. If you select one of the entries in the table, you can view the request and response in the message editor. Notice that the usernameparameter contains a different value from our payload list in each request.
The attack window contains several columns displaying key information about each response. Wait for the attack to finish, then click the heading of the Lengthcolumn to sort the results. As you can see, one of the responses is a different length. This difference in response from the server is worth further investigation.
Select any request from the list to display it in the message editor. Studying the responses, notice that most contain an Invalid username error message, but the one with the different length response has an Incorrect passworderror message. This different response strongly suggests that this username might be valid in this case.
Now that you have a potentially correct username, the next logical step is to try to brute-force the password. Try repeating this attack, using the username you have identified and this list of candidate passwords. You can view the complete solution to the lab here.
Feb 26, 2024 · When using Burp Suite Intruder to perform an attack, the first step is to examine the positions within the request where we want to insert our payloads. These positions inform Intruder about the locations where our payloads will be introduced (as we will explore in upcoming tasks).
Apr 19, 2011 · If you use Burp a good bit you’ve likely run into the question of what precisely the various Intruder Payload Methods do. Specifically, what are the differences between them? To refresh the memory, they are Sniper, Battering Ram, Pitchfork, and Cluster Bomb.
Configure a single payload position at the parameter's value. Use a suitable payload type to generate potential identifiers to test, using the correct format or scheme. Identify a feature of the response from which valid identifiers can be reliably inferred, and configure Burp accordingly.
The automatic placement of markers places payloads into the value of various types of request parameter, including URL query string parameters, body parameters, cookies, multipart parameter attributes (e.g. the filename in file uploads), XML data and element attributes, and JSON parameters.
