# slowloris.py - Simple slowloris in Python

## What is Slowloris?

Slowloris is basically an HTTP Denial of Service attack that affects threaded servers. It works like this:

1. We start making lots of HTTP requests.

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

3. We never close the connection unless the server does so. If the server closes a connection, we create a new one keep doing the same thing.

This exhausts the servers thread pool and the server can't reply to other people.

## How to install and run?

You can clone the git repo or install using **pip**. Here's how you run it.

* `sudo pip3 install slowloris`

* `slowloris example.com`

That's all it takes to install and run slowloris.py.

If you want to clone using git instead of pip, here's how you do it.

* `git clone https://github.com/gkbrk/slowloris.git`

* `cd slowloris`

* `python3 slowloris.py example.com`

### SOCKS5 proxy support

However, if you plan on using the `-x` option in order to use a SOCKS5 proxy for connecting instead of a direct connection over your IP address, you will need to install the `PySocks` library (or any other implementation of the `socks` library) as well. [`PySocks`](https://github.com/Anorov/PySocks) is a fork from [`SocksiPy`](http://socksipy.sourceforge.net/) by GitHub user @Anorov and can easily be installed by adding `PySocks` to the `pip` command above or running it again like so:

* `sudo pip3 install PySocks`

You can then use the `-x` option to activate SOCKS5 support and the `--proxy-host` and `--proxy-port` option to specify the SOCKS5 proxy host and its port, if they are different from the standard `127.0.0.1:8080`.

## Configuration options

It is possible to modify the behaviour of slowloris with command-line

arguments. In order to get an up-to-date help document, just run

`slowloris -h`.

* -p, --port

* * Port of webserver, usually 80

* -s, --sockets

* * Number of sockets to use in the test

* -v, --verbose

* * Increases logging (output on terminal)

* -ua, --randuseragents

* * Randomizes user-agents with each request

* -x, --useproxy

* * Use a SOCKS5 proxy for connecting

* --https

* * Use HTTPS for the requests

* --sleeptime

* * Time to sleep between each header sent
