This is a simple implementation in Python3 of the Slow Loris attack.

What is Slow Loris

Slow Loris is a HTTP/HTTPs DoS attack that affects only threaded servers. Basically, the server open one new thread to answer the request it receives. Then, the idea of Slow Loris is to open multiple connexions to the server and to send the request very slowly. Thus, the threads stay open, and if enough sockets are open, there is no thread left to answer new requests.

To use it

Download the script: git clone https://github.com/Gu1nness/SlowLoris.git

Execute the following command : python3 slow_loris.py <address>
