Notable usageĭuring the protests that erupted in the wake of the 2009 Iranian presidential election, Slowloris arose as a prominent tool used to leverage DoS attacks against sites run by the Iranian government. For example, lighttpd and nginx do not succumb to this specific attack.

Administrators could also change the affected web server to software that is unaffected by this form of attack. Other mitigating techniques involve setting up reverse proxies, firewalls, load balancers or content switches. Since Apache 2.2.15, Apache ships the module mod_reqtimeout as the official solution supported by the developers.

In the Apache web server, a number of modules can be used to limit the damage caused by the Slowloris attack the Apache modules mod_limitipconn, mod qos, mod_evasive, mod security, mod_noloris, and mod_antiloris have all been suggested as means of reducing the likelihood of a successful Slowloris attack. In general, these involve increasing the maximum number of clients the server will allow, limiting the number of connections a single IP address is allowed to make, imposing restrictions on the minimum transfer speed a connection is allowed to have, and restricting the length of time a client is allowed to stay connected. While there are no reliable configurations of the affected web servers that will prevent the Slowloris attack, there are ways to mitigate or reduce the impact of such an attack. In addition, certain servers are more resilient to the attack by way of their design, including Hiawatha, IIS, lighttpd, Cherokee, and Cisco CSS. Proxying servers and caching accelerators such as Varnish, nginx, and Squid have been recommended to mitigate this particular kind of attack.

Verizon's Motorola Set-top box (port 8082 and requires auth - unconfirmed)īecause Slowloris exploits problems handling thousands of connections, the attack has less of an effect on servers that handle large numbers of connections well.

Verizon's MI424-WR FIOS Cable modem (unconfirmed).

Trapeze Wireless Web Portal (unconfirmed).

Remember that you only can run the attack to a website of your property or you will get in serious legal issues.This includes but is not necessarily limited to the following, per the attack's author: The output of the attack will be the following one:Īs mentioned, the attack will never end unless you stop it. Replacing the values, the command should look something similar to: python3 slowloris.py īy default, the script runs with 150 sockets unless you specify it so, for example with 300 sockets instead: python3 slowloris.py -s 300 The -s or -sockets parameter specifies the number of sockets that will run simultaneously from the host of the attack. 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:

Slowloris is without a doubt, one of the favorite attacks of many white/gray/black hats, due to its simplicity and effectiveness.
