The website URL parameter specifies the website that you want to attack, for example. By default, it comes installed already in Kali Linux, so we will only need to run the slowloris.py script with the following command: python3 slowloris.py -s You will need Python 3.x installed on your Kali Linux system. For more information about the Python version of the Slowloris script, please visit the official repository at Github here. Now inside this directory we will be able to run the attack with the slowloris.py script. Then, switch from directory to the cloned one: cd slowloris Clone the repository with the following command in some directory of your terminal: git clone In order to run the attack, we need the logic of slowloris, however we won't write it by ourselves, instead, use the Python Slowloris implementation from an open source repository in Github. This exhausts the servers thread pool and the server can't reply to other people. If the server closes a connection, we create a new one keep doing the same thing.

We never close the connection unless the server does so.

We send headers periodically (every ~15 seconds) to keep the connections open.

Slowloris is basically an HTTP Denial of Service attack that affects threaded servers.

In this article, we will explain you how to run a Python version of a genuine Slowloris attack in Kali Linux. We recommend you to read the first article before proceeding with this one. Unlike another tutorial about how to test if your server is vulnerable to Slowloris attacks and where we explain how this kind of attack works, this tutorial aims to be a genuine attack, this means one of those attacks that are not limited by some condition in the script, this attack will run forever if you want it (until you close the terminal that runs the attack). Let's explain quickly graphically what the attack looks like: If you find bugs or have suggestions about improving the module, don't hesitate to contact me.Slowloris is without a doubt, one of the favorite attacks of many white/gray/black hats, due to its simplicity and effectiveness. Stop execution: Ctrl + C Testing Testing with real apache server $ docker-compose up web_server -d The following command helps to use module from command line $ slowloris -u -c 100 -s from_url ( '' ) connections_count = 100 loris = SlowLorisAttack ( url, connections_count, silent = True ) loris. Here is an example of usage from pyslowloris import HostAddress, SlowLorisAttack url = HostAddress. Note: Don't forget about 'sudo'! Example of usage How to use module through Python API

$ docker run -rm -it maxkrivich/pyslowloris Build image from source-codeДЄlso you can build image from Dockerfile and run a container: $ docker build -t pyslowloris. Pull the image from Docker Hub and run a container: $ docker pull maxkrivich/pyslowloris

Installation PyPiДЇor installation through the PyPI: $ pip install pyslowloris = 2.0.0 More information about the attack you can find here. Please DO NOT use this in the real attacks on the servers. The idea behind this approach to create as many connections with a server as possible and keep them alive and send trash headers through the connection. The module is based on python-trio for Asynchronous I/O and poetry for dependency management.

PySlowLoris is a tool for testing if your web server is vulnerable to slow-requests kind of attacks.
