There are many DDoS attack tools available on internet today. Some of these tools have legitimate purposes. For example security researchers and network engineers may at times perform tests against their own networks.
How are DDoS attack tools categorized?
Some DDoS attack tools are specialized and they only focus on a particular area of the protocol stack. Others will be designed to allow for multiple attack vectors. Attack tools can be characterized into several groups:
Low and slow attack tools
Just like what its name implies, these types of attack tools both use a low volume of data and operate very slowly. Such DDoS attack tool designed to send small amounts of data across multiple connections in order to keep ports on a targeted server open as long as possible. These tools continue to use server resources until a targeted server is unable to maintain additional connections. Low and slow attacks may at times be effective even when not using a distributed system such as a botnet and are commonly used by a single machine.
Application layer attack tools
These tools try to target layer 7 of the OSI model, where Internet-based requests such as HTTP occur. Using a type of HTTP flood attack to overwhelm a target with HTTP GET and POST requests, a malicious actor can launch attack traffic that is difficult to distinguish from normal requests made by actual visitors.
Protocol and transport layer attack tools
These tools utilize protocols like UDP to send large volumes of traffic to a targeted server. While such attacks are often ineffective individually, these attacks are typically found in the form of DDoS attacks where the benefit of additional attacking machines increases the effect.
Different types of DDoS attack tools
Here we are figuring out some common and effective tools. 15 commonly used tools include:
It sends legitimate HTTP traffic. Slowloris is the most effective tool for launching the DDoS attack. It opens multiple connections to the targeted web server and keeps them open as long as possible. It does this by continuously sending partial HTTP requests, which non of them is completed. The attacked servers open more and connections open, waiting for each of the attack requests to be completed.
This attack requires minimal bandwidth to affects the target server’s web server only. It has almost no side to effect on other services and ports.
2. LOIC (Low Orbit Ion Canon)
The Low Orbit Ion Cannon (LOIIC) basically direct computer’s network connection towards a target web server. On its own, one computer rarely generates enough TCP, UDP, or HTTP requests at once to overwhelm a web server. So garbage requests can easily ignored while legit requests for web pages are responded to as normal.
GoldenEye is another popular tool which is used for security testing purposes. This tool is capable of attacking victims’ web servers. Actually GoldenEye tool is only used for security testing purposes. It was developed in Python for testing DOS attacks, but people also use it as hacking tool.
4. HOIC (High Orbit Ion Canon)
The High Orbit Ion Cannon (HOIC) is a tool that could help an unauthenticated, remote attacker in conducting distributed denial of service (DDoS) attacks. It functions by flooding target systems with junk HTTP GET and POST requests. High Orbit Ion Canon or HOIC is developed by nameless group, a hacktivist collective, to replace the Low Orbit Ion Cannon (LOIC) tool.
The tool can open up to 256 simultaneous attack sessions at once. It can easily bringing down a target system by sending a continuous larg amount of junk traffic until legitimate requests are no longer able to be processed. Variation techniques of HOIC make it more difficult for traditional security tools and firewalls to identify and block DDoS attacks.
XOIC is a nice DoS attacking tool. It performs a DOS attack on any server with an IP address, a user-selected port, and a user-selected protocol. Developers of XOIC claim that XOIC is more powerful than LOIC in many ways. Like LOIC, it comes with an easy-to-use GUI, so a beginner can easily use this tool to perform attacks on other websites or servers.
6. RUDY (R U Dead Yet ?)
RUDY is a popular low and slow attack tool that is designed to crash a web server by submitting long form fields. The attack is conducted via a DoS tool which browses the target website and discovers embedded web forms. When the forms have been identified, RUDY sends a legitimate HTTP POST request with an abnormally long content-length.
7. TOR’s Hammer
ToR’s Hammer was designed to be run through the ToR network to anonymize the attack and limit mitigation. The problem with this strategy is that the ToR network tends to be very slow. So this will limit the rate at which the packets can be sent and thereby limit the effectiveness of this tool.
This DDoS tool doesn’t require huge amounts of bandwidth and can be conducted with a single system. It attacks vulnerabilities in SSL to bring down the server.
PyLoris is said to be a testing tool for servers. It can be used to perform DOS attacks on a service. This tool can utilize SOCKS proxies and SSL connections to perform a DOS attack on a server. It can target various protocols, including HTTP, FTP, SMTP, IMAP, and Telnet. Unlike other traditional DOS attacking tools, this tool directly hits the service.
This DDoS attack tool would help you to reproduce several MITM, DoS, DDoS attack scenarios.
This is one of the best tools of DDoS attack. It is used to send TCP/IP, ICMP, SYN/ACK, UDP packets. Also, it displays target replies. This tool can be used for TOS (the type of service), packet size, fragmentation, Test firewall rules, etc.
12. HULK (Http Unbearable Load King)
HULK is another nice DOS attacking tool. It used to attack web server by generatig volumes of unique and obfuscated traffic. This tool uses many other techniques to avoid attack detection via known patterns.
This stands for DDoS attacks via other sites execution tools. It conduct DDoS attack on the site via Abuse of Functionality and XML External Entities vulnerabilities at other sites. The latest version of the tool has added support for cookies along with many other features.
14. OWASP DoS HTTP POST
This tool is used to examine the stability of your web applications against SLL renegotiation, HTTP Post, and Slowloris. You can use this tool to check whether your web server is able to defend DOS attack or not. Not only for defense, it can also be used to perform DOS attacks against a website.
15. Appache BenchMark tool
Actually Appache BenchMark tool is used to test a load of servers by sending many simultaneous requests. But it can use as one of DDoS attack tools. It can be used to benchmark HTTP servers.
DDos Attack Tools For Android
AnDOSid is an android tool developed by Scott Herbert. You can use this tool to launch DoS attacks from your mobile phone. It was developed as a stress testing tool. As you know, anything can be misused, even a pen. AnDOSid is so powerful, that you can even use it to attack web servers.
Low Orbit Ion Cannon is a simple application that allows users to send UDP, HTTP, or TCP data packets to any IP address. As LOIC supports all three socket protocols such as UDP, TCP, and HTTP, it can be used with any type of server.
The list of tools mentioned in this article are the most popular DDoS attack tools. These tools can be great resources for performance and security testing.
Briefly talking, HULK will be a good tool for research purposes. LOIC and XOIC are easy to use. LOIC can be used for testing. RUDY and PyLoris are also created especially for testing purposes.
