The Ultimate Guide to Using Slowloris DDoS Attack Tool

Welcome to the ultimate guide on mastering the Slowloris DDoS attack tool! In the realm of cyber warfare, understanding the intricacies of Denial of Service (DoS) attacks is paramount. Slowloris, a notorious tool, stands out for its effectiveness and stealth in causing service disruptions. In this comprehensive guide, we’ll delve into the inner workings of Slowloris, unravel its mechanisms, and equip you with the knowledge to wield it effectively.

Whether you’re a cybersecurity enthusiast, an ethical hacker, or a defender of digital fortresses, this guide will empower you to comprehend and potentially defend against this potent cyber threat. Let’s embark on this journey to unlock the potential of Slowloris and navigate the complex landscape of cybersecurity.

A free and open-source utility called Slowloris can be available on Github. With this tool, we can launch a denial-of-service assault. The programming language Python was used to write this framework. This malware leverages entirely valid HTTP traffic to enable one machine to bring down the web server of another.

After establishing a complete TCP connection, it simply needs a few hundred queries spaced out over a prolonged period of time. Because of this, the program doesn’t need to use a lot of traffic to use up all of a server’s connections.


  • Slowloris sends numerous requests to the target, resulting in high traffic botnets.
  • Slowloris can be used to launch DDoS attacks against any website.
  • It is an open-source program, so you may get it for free from GitHub.
  • It makes use of totally legal HTTP traffic.
  • Slowloris can be used to carry out a denial of service attack by creating a large amount of botnet traffic.

Slowloris tool installation and step-by-step implementation:

Step 1: Launch Kali Linux and then the Terminal.

Step 2: Run the following command to create a new directory on your desktop called Slowloris.

mkdir Slowloris

Step 3: Navigate to the directory you need to create (Slowloris).

cd Slowloris

Step 4: Now clone the Slowloris tool from Github in order to install it on your Kali Linux machine. To do so, simply type the following URL into your terminal within the Slowloris directory you created.

git clone

You have completed the installation of the Slowloris tool in Kali Linux. It’s now time to perform a denial of service using the steps below.

Step 5: Now, go to the Action bar and click on split terminal vertically. The two-terminal screen should now be open.

Step 6: You need to verify your machine’s IP address in order to run the following command.


Step 7: As you can see, we now have our IP address, so it’s time to start the apache server. Run the following command to start the apache server.

sudo service apache2 start

Step 8: To determine whether your server is active or not, run the following command.

service apache2 status

Step 9: We can see that our server is in active mode, which means it is operational. Return to the first terminal and run the following command to check permissions.

ls -l

Step 10: Run the tool with the following command.

python3 (your ip address) -s 500

Step 11: You can see that the tool has begun attacking that specific IP address that we have provided. To test whether it is working, go to your browser and type that IP address into the URL bar, and you will see that the site is only loading and loading but not opening. This is how the Slowloris tool works.


In the ever-changing cybersecurity world, being updated about possible attacks is critical. This post has investigated the Slowloris DDoS attack tool in Kali Linux, providing light on its mechanisms and giving mitigation measures. You empower yourself to protect your online assets against rising risks by applying this information.
