The main benefit of Turbo Intruder is that you can apply any custom logic you like using Python/Jython.

You may find the following guide useful: https://www.educative.io/answers/how-to-use-base64b64encode-in-python

You can find a basic example below:
import base64

def queueRequests(target, wordlists):
    engine = RequestEngine(endpoint=target.endpoint,

    string = 'asdf'
    string_encode = string.encode('utf-8')
    encoded = base64.b64encode(string_encode)
    for i in range(10):
        engine.queue(target.req, encoded)

def handleResponse(req, interesting):
    # currently available attributes are req.status, req.wordcount, req.length and req.response
    if req.status != 404:

Hi You can find the documentation for using Turbo Intruder here: https://portswigger.net/research/turbo-intruder-embracing-the-billion-request-attack It looks like there is a multi-host example script built in to Turbo Intruder. You can find it in the scripts dropdown when you are configuring an attack.

Hi dear Hannah and other friends sorry for disturbing again in your example instead of one string(string = 'asdf')how Can I write password list file path and attack with my passlist? best regards

You could provide an array of items and loop through those. Alternatively, you could read input directly from a file. As you can use Python code to write your own custom logic, there is a wide variety of functionality you can implement.

Ok that's right but I am beginner at python and burp suite can you please write your example as wrote before and just add how to write passlist path directory instead of one string? Thank you

Hi The basic.py example shows how to queue requests using information retrieved form the filesystem. Make sure that you replace the file path with one that is valid on your machine!
