This extension adds Ruby scripting capabilities to Burp Suite with an interface comparable to Burp's pure Java extension interface.

Buby lets you:

  • Intercept and log proxied requests and responses via Burp into Ruby and perform arbitrary processing on them.
  • Modify requests and responses in-line using Ruby scripts.
  • Pass requests and other information from JRuby to various sub-interfaces in Burp.
  • Use the Burp framework for active and passive scanning using arbitrary requests and responses.
  • Use the Burp framework for making arbitrary HTTP requests.

Requires JRuby version 1.7 or later.
