Burp Infiltrator is a tool for instrumenting target web applications in order to facilitate testing using Burp Scanner. Burp Infiltrator modifies the target application so that Burp can detect cases where its input is passed to potentially unsafe APIs on the server side.
The initial release of Burp Infiltrator supports applications written in Java or other JVM-based languages such as Groovy. Java versions from 4 and upwards are supported. In future, Burp Infiltrator will support other platforms such as .NET.
