Slow Read DoS attack aims the same resources as slowloris and slow POST, but instead of prolonging the request, it sends legitimate HTTP request and reads the response slowly. This tool is sending partial HTTP requests, trying to get denial of service from target HTTP server. If the server keeps too many resources busy, this creates a denial of service. If an HTTP request is not complete, or if the transfer rate is very low, the server keeps its resources busy waiting for the rest of the data. Slowloris and Slow HTTP POST DoS attacks rely on the fact that the HTTP protocol, by design, requires requests to be completely received by the server before they are processed.

The Slowhttptest library is available from the repositories, so you can easily install it from the command line with the following command: # update repos firstįor more information about this tool, please visit the official repository at Github here.

In this article, we'll teach you how to install slowhttptest on your Kali Linux system and how to use it to perform this attack on your servers.

SlowHTTPTest works on majority of Linux platforms, OS X and Cygwin - a Unix-like environment and command-line interface for Microsoft Windows, and comes with a Dockerfile to make things even easier.Ĭurrently, the supported attacks by the slowhttptest library are: Use it to test your web server for DoS vulnerabilites, or just to figure out how many concurrent connections it can handle. So, how you can perform such attack easily to a server and don't die trying ? The SlowHTTPTest is a highly configurable tool that simulates some Application Layer Denial of Service attacks by prolonging HTTP connections in different ways. For education, the cashier won't kick the grandmas out of the store until they end up telling the story. Didn't get it ? Imagine sending 100 old grandmas to a store, with all of them trying to tell a story from their childhood to the cashier so that no other customers can buy anything. It's just, pretty simple right? However for a bad configured server this can be the doom, the hardware won't be pushed up to the limits, however it hangs basically for education.

Let's explain quickly graphically what the attack looks like: One of those tricky attacks are the Slow HTTP attacks that target any kind of web server. Most of web administrators that doesn't care properly about the security of the servers, are often target of attacks that a lot of black hat hackers know how to perform in mass.
