Burp Spider is a tool for automatically crawling web applications. You can use this in conjunction with manual mapping techniques to speed up the process of mapping an application's content and functionality.
Before performing any automated spidering, it is generally preferable to carry out some manual preparatory work:
Note: Although this manual process is more time consuming than proceeding directly to automated crawling, it is generally safer and more effective.
Burp Spider uses various techniques to crawl application content, and by default it will follow all in-scope links, submit forms with dummy data, and make additional requests (for robots.txt, directory roots, etc.). In some situations, running an automated spider in this way can result in unintended consequences, such as registering new user accounts, generating feedback emails, or changing other application state. You should use any automated tools with caution, if possible against only non-production systems. You should also closely review the Spider settings before use, and ensure that these are suitable for your application and your requirements. In particular, you should review the following details:
Note: When running, the Spider will follow links for any URLs that are within the currently defined scope. For example, if you define a whole domain as being in scope, and then initiate spidering from a single branch in the site map, the Spider may still request items that are outside that branch, but within the wider scope. To ensure that the Spider only requests items within a specific branch, you should first configure the spidering scope to include only this branch.
If you have already performed manual application mapping, and configured a suitable spidering scope, then you can begin spidering by pressing the "Spider is running / paused" toggle button on the Control tab.
Alternatively, you can select a branch of the target site map, or a request anywhere within Burp, and initiate spidering via the context menu. If you do this for a branch or item that is not currently in the spidering scope, Burp will prompt you for confirmation, and if you do so Burp will expand the current scope to include the specified item and any sub-items within the site map.
When spidering a selected branch of the site map, Burp will carry out the following actions (depending on your settings):
Note: When spidering, or performing other content discovery tasks, you can easily monitor the site map to identify items that have been newly added. To do this, select the entire application within the site map tree, and sort the table view on the "Time requested" column (click the column header to cycle through ascending sort, descending sort, and unsorted). This will order the table entries according to the time they were requested, allowing you to quickly identify new items as they appear.
