Slowloris is an HTTP Denial of Service attack tool that affects threaded servers. It is developed using python language. The bot starts to make lots of HTTP requests and then sends headers periodically ( every 15 seconds ) to keep the connections open. It never closes the connections unless the server does. (This exhausts the server thread pool and the server can’t reply to other people).

Note: In this tutorials we only EVER hack our own systems as a proof of concept and never engage in any black hat activity. We are not responsible for the damage you cause.
