10 Common DDoS Attack Tools

Are you searching for the best DDoS Attack Tools/Software and are tired of searching for them? If yes, then don’t worry because you have ended up in the right place. This article will give you a list of such best DDoS Attack Tools, and will also answer some of the most common questions about it.

What is DDoS?

DoS (Denial of Service) is an attack used to deny legitimate users access to a resource such as accessing a website, network, emails, etc. Distributed Denial of Service (DDoS) is a type of DoS attack that is performed by several compromised machines that all target the same victim. It floods the computer network with data packets.

Numerous DDoS attack tools can create a distributed denial-of-service attack against a target server. Following is a handpicked list of DDoS Attack Tools, with their popular features and website links. The list contains both open source (free) and commercial (paid) DDoS tools.

10 Common DDoS Attack Tools

DDoS Attacks or Solarwinds

Solarwinds is a DDOS tool that can be used to perform a DDoS attack. It is an easy-to-use APT software that detects threats across environments for cohesive defense-in-depth security.


  • SEM consists of features such as sending alerts, shutting down an account, or blocking an IP
  • The tool allows you to configure the options by using the checkboxes.
  • It keeps the events and logs in an encrypted format and records them in a read-only form.
  • The methods of maintaining catalogs and events will make SEM one of the best tools
  • SEM allows you to customize filters according to specific timeframes, accounts/IPs, or combinations of parameters.

LOIC (Low Orbit ION cannon)

LOIC (Low Orbit ION cannon) is an easy-to-use and open-source DDOS tool software that is widely used for network stress testing and DDoS attack.


  • It allows the users to perform stress testing to verify the stability of the system.
  • It never hides IP addresses.
  • With the help of basic network traffic monitors and firewalls, small-scale attacks can be detected and blocked easily.
  • It uses a unique client classification engine that analyzes incoming HTTP/S traffic.

DDoS Attack Tools: Pyloris

Pyloris is a slow HTTP DoS tool that enables the attacker to craft its HTTP request headers. These include the packet header, cookies, packet size, timeout, and CRLF option.

Pyloris objective is to keep TCP connections open for as long as possible between the attacker and the victim’s servers. This results in exhausting the server’s connection table resources. Once the server’s connection table is finished, it will not be able to handle new connections from legitimate users, resulting in a denial of service.


  • It has an easy-to-use GUI.
  • The attack can be made on HTTP, FTP, SMTP, IMAP, and Telnet.
  • It directly makes a service attack.


DDoSIM is a tool used in a laboratory environment to simulate a distributed denial-of-service attack against a server. The test shows the capacity of the server to handle application-specific DDoS attacks. It is written in C++ and runs on Linux.

It simulates several zombie hosts that create full TCP connections to the target server. After completing the link, DDoSIM starts the conversation with the listening application.


  • It attacks the server by reproducing zombie hosts.
  • The hosts create a TCP connection with the server.
  • It can do HTTP DDoS attacks using certain requests.

DDoS Attack Tools: RUDY

RUDY is short for R-U-Dead-Yet and is one of the free DDoS attack tools that implement the generic HTTP DoS attack via long-form field submissions.


  • It targets web applications by starvation of available sessions on the webserver.
  • It performs load testing.
  • It provides an interactive console menu.
  • It keeps sessions at a halt using never-ending POST transmissions and sending an arbitrarily large content-length header value.
  • It is a simple and easy-to-use tool.

HTTP Unbearable Load King (HULK)

HULK (HTTP Unbearable Load King) is a Denial of Service tool used to attack web servers by generating unique and obfuscated traffic volumes. HULK’s generated traffic also bypasses caching engines and hits the server’s direct resource pool.


  • It generates a great volume of traffic at the server.
  • It can bypass the cache engine.

HOIC (High Orbit ION cannon)

HOIC (High Orbit ION cannon) is a free denial-of-service DDOS tool that can attack more than one URL at the same time.


  • It provides a high-speed multi-threaded HTTP Flood.
  • It simultaneously floods up to 256 websites at once.
  • It provides an easy-to-use interface.
  • It can be ported over to Linux/Mac with a few bug fixes.
  • It provides three settings to control attacks.
  • It provides a built-in scripting system to allow the deployment of ‘boosters’.
  • It can select the number of threads in an ongoing attack.


Slowloris is a DDoS attack software that enables a single computer to take down a web server. Due to this attack’s elegant yet straightforward nature, it requires less bandwidth to implement and affects the target web server only, with almost no side effects on other ports.

Slowloris is highly-effective against many types of web server software, which includes Apache 1.x and 2.x. Slowloris has been credited with several high-profile server takedowns. It was used by Iranian ‘hacktivists’ following the 2009 Iranian presidential election to attack Iranian government websites.


  • It sends HTTP traffic to the server.
  • It doesn’t affect other ports on the target network.
  • This attack tries to keep most of the connections that are engaged with those that are open.
  • It holds the links as long as possible.
  • As the server supports the false connection available, this will overflow the connection pool and deny the right connections.

Tors Hammer

Tor’s Hammer is a slow post-DDoS testing tool written in Python. You can also run it through the Tor network. The idea behind the Tor’s Hammer attack is to saturate the entire TCP stack for the HTTP/S daemon; It is done by slowly opening up connections and then sending an incomplete request to keep the link alive as long as possible. The tool does this slowly, and it is possible that a single attacking machine can take down a web server.


  • You will remain unidentified if you run it through the Tor network.
  • Use to run it through Tor.
  • The attack can be made on IIS servers and Apache with this tool.


GoldenEye is a DDoS tool app that is written in python for security purposes only. It is an HTTP DoS Test Tool.


  • It is fast and easy to use.
  • It performs load testing.
  • It randomizes GET, POST to get the mixed traffic.


DDoS attacks are mostly used to crash servers, destroy websites and disrupt services. While developing websites or servers should set up a way to detect and block DDoS attacks. On the internet, there are many other tools available, that can help you to make it easier to perform DOS attacks against a server or website.

From these available tools, few tools support a zombie network for DDoS attacks. LOIC is the one of these, that is the most used and most popular DOS attacking tool. So, every company has to take care of such malpractices and needs to set up a good level of protection against DDoS attacks. So, Which DDos Attack tools you are using. Let us know in the comment section.
