Filtering the site map with Bambdas

You can write Java-based Bambdas to create custom filters for your site map.

Two objects of the Montoya API are available to help you write your Bambdas:

• SiteMapNode

• Utilities

To create a Bambda to filter your site map:

1. In the Target > Site map tab, click the filter bar to open the Site map filter window.

   The filter bar only appears when there is one or more items in your site map.

2. Click the Bambda mode tab.

3. Write your Bambda using Java.

4. Click Apply.

Burp compiles your Bambda and applies it to every item already logged in your site map, and to any future site map items generated in this project.

Example Bambda

In the example below, we'll create a Bambda that filters the site map to show only items that meet the following criteria:

• The item must have a POST method.

• The item must have an issue reported against it.

In this example, our Bambda is:

return node.requestResponse().request().method().equals("POST") && !node.issues().isEmpty();

Converting site map filter settings to Bambdas

If you have already used Settings mode to configure a site map filter, you can convert these settings to a Bambda.

To convert your filter settings to a Bambda:

1. In the Target > Site map tab, click the filter bar to open the Site map filter window.

2. Make changes to the filter settings (if necessary).

3. At the bottom of the Site map filter window, click Convert to Bambda.

Your filter is now converted into a Bambda, enabling you to customize it further using Java.
