Burp Suite

Installing

Mac

Use the Mac installer provided by portswigger: https://portswigger.net/burp/communitydownload

Debian Linux

Dependencies

The jarwrapper library is required to install burpsuite:

sudo apt-get install jarwrapper

Installing burpsuite with KaliTools

Use KaliTools to install burpsuite on a non-Kali machine:

cd kali-tools
python3 kali.py burpsuite
cd dist/burpsuite
dpkg-buildpackage -us -uc -b
cd ../
sudo dpkg -i burpsuite_1.7.30-0kali1_all.deb
sudo apt-get upgrade burpsuite

Incompatible JRE

Ran into a problem with the Burp Suite community edition:

"Your JRE appears to be version 11.0.14 from Debian. Burp has not been fully tested on this platform and you may experience problems."

I used aptitude to install the openjdk-11-jre package, and that's the package causing the above error. It seemed like it should have been working fine. I tried upgrading jarwrapper, and that did the trick:

sudo apt-get -y upgrade jarwrapper

Usage

Proxy

Intercepting Traffic

One basic use of Burp is intercepting traffic.

To do this, go to Proxy > Intercept. You can open the Chromium browser included with Burp, which will use the Burp proxy.

When you open the browser, it will not intercept traffic by default, you have to click "Intercept Off" to switch it to "Intercept On".

Once you do that, you'll see each request come up as it is happening in the browser, and you can Forward the request or Drop it.

You will see all requests that are made as part of loading a page, so if there are multiple API calls being made, you'll see each one as a separate request.

Modifying Traffic

The content of requests can also be modified before the request is forwarded.

The first Burpsuite tutorial [1] on intercepting traffic demonstrates how this can be used to exploit a vulnerable e-commerce shopping site.

Official Tutorials

Tutorial 1: intercepting HTTP traffic: https://portswigger.net/burp/documentation/desktop/getting-started/intercepting-http-traffic

• Burp Proxy lets you intercept HTTP requests and responses sent between your browser and the target server
• Enables studying behavior of websites when different requests are sent
• Open Burpsuite and go to Proxy > Intercept
• Click Open Browser, which opens a built-in, embedded browser
• Can browse without intercept turned on, normal experience
• Turning on intercept will show each request, give the option to forward or drop
• Proxy also records a history of each request
• Burp Proxy also lets you modify HTTP requests
• (Tutorial requires setting up an account on portswigger and using an example vulnerable website)
• Basically you can just edit the request when you see it, before you click Forward or Drop
