  • Automatically Change Response

    Hi, I am currently developing a Burp plugin in python and do have a problem for which I don't have a solution. I basically want to automatically change the response but I do have a plugin in between that decodes my binary. What I have achieved until now is that I see my decoded message as a new tab in the proxy and target view. I can also manipulate the response by intercepting it first a...

  • Extensions class loading

    Hello, I was wondering if Burp supports class loading from extensions.

My question is - is it possibl...
