Burp Suite Free Edition v1.6 released

Burp Suite Free Edition v1.6 is now available to download.

This is a significant upgrade with a wealth of new features added since v1.5, including:
  • Support for WebSockets messages.
  • Support for PKCS#11 client SSL certificates contained in smart cards and physical tokens.
  • A new Extender tool, allowing dynamic loading and unloading of multiple extensions.
  • A new powerful extensibility API, enabling extensions to customize Burp's behavior in much more powerful ways.
  • Support for extensions written in Python and Ruby.
  • A new BApp Store feature, allowing quick and easy installation of extensions written by other Burp users.
  • An option to resolve DNS queries over a configured SOCKS proxy, allowing access to TOR hidden services.
  • Generation of CSRF PoC attacks using a new cross-domain XHR technique.
  • New options for SSL configuration, to help work around common problems.
  • Optional unpacking of compressed request bodies in the Proxy.
  • Support for .NET DeflateStream compression.
  • New and improved types of Intruder payloads.
  • New Proxy interception rules.
  • New Proxy match/replace rules.
  • Improved layout options in the Repeater UI.
  • An SSL pass-through feature, to prevent Burp from breaking the SSL tunnel for specified domains.
  • Support for the Firefox Plug-n-hack extension.
  • An option to copy a selected request as a curl command.
And the best thing about Burp upgrades? No one pays for them ...

The Free Edition is and always will be free, despite its huge capabilities.

Burp Suite Professional still costs only $299, and all licensed users can upgrade without any extra charge. We haven't changed the price for two-and-a-half years, despite two major updates and nearly forty minor updates. Even better? We've already said that we won't be hiking the price during 2014.

Have fun!

Introducing the BApp Store

Today's release of Burp includes a brand new feature: the BApp Store. This contains Burp extensions that have been written by users of Burp Suite, to extend its capabilities.

You can install BApps with one click from within Burp:


You can also download BApps from the BApp Store web site, for manual installation on Burp machines without an Internet connection:


All BApps are free! We may support paid-for BApps in future, but we have no current plans to do so.

We really hope that the new feature will help users find and use good quality Burp extensions that other users have shared. You can rate BApps that you have used, and see the aggregated ratings submitted by other users.

We also hope that the BApp Store will encourage more extension authors to create and share great Burp extensions. We'll be adding more BApps to the store in the near future. If you have written or are aware of a great Burp extension that you'd like included in the BApp Store, please submit your BApp to us.

Burp Suite Pro shines in new survey

A new survey has just been published comparing the performance of 63 different web application security scanners. This is what it says overall about Burp Suite Pro:
"Burp is the undisputed winner of the overall versatility category, was the winner in the input vector support category, got one of the highest scores in detecting Backup/Hidden Files, and decent scores in many other categories. It also came out FIRST in the SQL Injection and Reflected XSS categories, and dramatically improved its RFI score."
There is a lot of technical detail in the survey results that we plan to work through, to understand exactly how Burp performed, and can be improved even further.

In the past few months, we've made numerous significant enhancements to Burp Scanner, adding support for nested insertion points, new payload encodings, new categories of vulnerability, and improved coverage of existing scan checks. But we're far from complacent: this year we will continue enhancing the Scanner engine to find even more edge-case vulnerabilities, and also the Spider tool to improve Burp's fully automated crawling capabilities.

As always, new features and enhancements to Burp Suite Pro are made available free to licensed users, and the cost of a Burp license will not be increasing during 2014.

  • Various Scanner engine enhancements, including several new checks
  • Options to optimize the Scanner for speed and accuracy
  • Nested Scanner insertion points, to handle XML within JSON within a URL parameter, etc.
  • New extensibility API
  • Ability to load multiple extensions, and load/unload dynamically via the UI.
  • Support for extensions written in Python and Ruby
  • CSRF PoC generator
  • Importable / exportable SSL CA certificates
  • Workarounds for various Java SSL issues
  • Support for PKCS#11 smart card authentication
  • SSL passthrough function
  • sslstrip functionality
  • "Copy as curl command" feature
  • New Intruder payload types
  • Support for Firefox plug-n-hack
  • Numerous other small enhancements throughout the suite.
All updates are made available to licensed users without any additional charge.

Today, we pledge that we will not increase the USD price of Burp Suite Pro during 2014. Instead of hiking the price, we'll continue to add great new features. We have some fantastic ideas in the pipeline, and if all goes well we will be making one or two really big announcements in the course of 2014.

Happy new year!

Burp support for Firefox Plug-n-Hack

The Firefox browser has recently added support for a new way of easily configuring the browser to work with intercepting proxy tools like Burp. To use this, you need to install a Firefox plugin called Plug-n-Hack:


The plugin is currently beta and also requires the latest beta version of Firefox, but when it is stabilized it will be available on the Firefox Marketplace.

If you have installed the Plug-n-Hack plugin, configuring a clean installation of Firefox to work with Burp is pretty straightforward. First, in your browser, enter the URL to connect directly to your Burp Proxy listener (by default 127.0.0.1:8080):


On the Burp welcome page, follow the Plug-n-Hack link:


Click on the "Configure your browser" button, and accept the warning displayed by the plugin:


If everything worked, you will see a "Configuration succeeded" message:


The configuration will have carried out two tasks. Firstly, it will configure your browser to use Burp as its proxy server, via a proxy auto-configuration file created by Burp:


Secondly, it will install Burp's SSL CA certificate as a trusted root in your browser, to eliminate SSL warnings when intercepting traffic to SSL web sites:


Hopefully the new Plug-n-Hack support might make life a bit easier next time you are setting up Burp on a new machine.
