![]() You will have two options under payload set. When you go to the payloads tab it will be slightly different. Also take note that we switched the attack type to “ Cluster bomb“. We will go through the same steps, except in the positions tab we will need to highlight both the username and password fields. While it’s unlikely a single user has a weak password, it’s much more likely that one of many users has a weak password. This is going to be a similar, however in this case we are assuming we have a list of usernames. Another method is to click the “ Options” tab and use “ Grep – Match” or “ Grep – Extract” to flag items with keywords or strip out certain strings from within the responses. Typically I will sort by length to find differences in responses. When you get the results, you are going to want to look for differences in the responses. Either paste in your wordlist from the clipboard, or click the “ load…” button and select a wordlist file. Switch to the payload tab and keep the payload type set to “ simple list“. All you need to do is start by sending the POST request associated with the logon to Burp Intruder.Ĭlear out all the auto selected parameters, and then highlight the password field and click the “ add” button. While tools like Hydra exist for this purpose, I find that it is much easier to tune in burp. Often times penetration testers will want to brute force passwords to gain access, or to test password lockout policy in an application. Here are a few pro-tips to get the most out of your web application tests. There are a few things however, that while they exist in Burp Suite, they are not completely intuitive. The feature set is rich, and anything that it does not do by default can usually be added with an extension. Additional features that I hope to implement at some point include alerting, monitoring, and integration with other services such as Amazon S3, Microsoft OneDrive, and Google Cloud Storage.Burp Suite is one of my favorite tools for web application testing. Though I have only scratched the surface of what’s possible, Seltzer has been a fun project to work on. Seltzer supports the use of Burp REST API keys as an additional level of security if users want to further restrict access to the API. For example, the API typically should not be exposed to the public internet. It is important to note that the Burp REST API should be properly configured prior to using Seltzer. ![]() It leverages the Burp REST API to allow for using named scan configurations, Burp project and user options files, and it runs in headless mode by default. This begs the question, “What is Seltzer?” Seltzer is a Burp Suite extension and accompanying Bash shell script that allows a user to scan a list of targets using Burp 2.0. The workflow might look something like this: We can combine the extender API, the REST API, and some Bash scripting to achieve our goal of headless, unattended scanning in Burp 2.0. Specifically, the REST API provides a means for us to start scans, specify a scan configuration profile to use, and check the scans status. Currently, the REST API has limited functionality, but it is useful for solving this problem. However, another feature of Burp 2.0 is the Burp REST API. We cannot use the extender API in its current form to do this. More specifically, we would like to traverse a list of targets and do the following: We would like to use the extender API to start a scan and specify a configuration. When new scans are initiated via the extender API, they use a very limited default configuration. When PortSwigger released Burp 2.0, the Burp Extender API was not updated to support some of the new features including the ability to specify a configuration for a new scan. In Burp 2.0 you can have concurrently running scans, each having its own configuration. In Burp 1.0, all active scans used the same configuration. ![]() It is a great extension that has worked well, until the release of Burp 2.0.īurp 2.0 is a significant upgrade from 1.0 and includes many useful new features, such as the ability to create multiple scanning configurations. Available in the BApp Store, Carbonator provides a means to interact with Burp via the command line, scanning a target and exporting the results as HTML. For years, my tool of choice for this has been the Burp extension Carbonator. Alternatives such as Burp Suite Enterprise exist, but those of us with Burp Suite Professional may want to leverage it to perform this type of work. However, it can be difficult to use Burp for headless, unattended scanning. It is feature-rich, intuitive, well-supported, and customizable. Burp Suite Professional (Burp) is one of the best tools available for penetration testers.
